Answer 1

The given problem can be exemplified in the following diagram:

In the diagram we have the following forces:

\(\begin{gathered} F=\text{ pushing force} \\ F_x=\text{ x-component of the force} \\ F_y=\text{ y-component of the force} \\ N=\text{ normal force} \\ F_f=\text{ friction force} \\ W=\text{ weight} \end{gathered}\)

Now we will determine the value of the acceleration of the box. To do that we will add the forces in the horizontal direction:

\(\Sigma F_h=F_x-F_f\)

According to Newton's second law we have that the sum of forces must be equal to the product of the mass and the acceleration:

\(F_x-F_f=ma\)

To determine the value of the friction force we use the following relationship:

\(F_f=\mu N\)

To determine the value of the normal force we add the forces in the vertical direction:

\(\Sigma F_v=N-F_y-W\)

Since there is no movement in the vertical direction we have:

\(N-F_y-W=0\)

Now we solve for the normal force:

\(N=F_y+W\)

To determine the vertical component of the force we use the right triangle shown in the diagram. We use the function sine and we get:

\(\sin 35.7=\frac{F_y}{F}\)

Now we multiply both sides by "F":

\(F\sin 35.7=F_y\)

Now we substitute this value in the formula for the normal force:

\(N=F\sin 35.7+W\)

Now we substitute this value in the formula for the friction force:

\(F_f=\mu(F\sin 35.7+W)\)

Now we substitute this value in the formula for the horizontal forces:

\(F_x-\mu(F\sin 35.7+W)=ma\)

Now, to determine the horizontal component of the force we use the function cosine:

\(\cos 35.7=\frac{F_x}{F}\)

Now we multiply both sides by "F":

\(F\cos 35.7=F_x\)

Now we substitute in the sum of horizontal forces:

\(F\cos 35.7-\mu(F\sin 35.7+W)=ma\)

Now we solve for "a" by dividing both sides by "m":

\(\frac{F\cos 35.7-\mu(F\sin 35.7+W)}{m}=a\)

To determine the mass we use the formula for the weight:

\(W=mg\)

Where:

\(g=\text{ acceleration of gravity}\)

Now we divide both sides by "g";

\(\frac{W}{g}=m\)

Now we substitute the values:

\(\frac{(401N)\cos 35.7-(0.587)(401N\sin 35.7+245N)}{\frac{245N}{9.8\frac{m}{s^2}}}=a\)

Solving the operations we get:

\(1.779\frac{m}{s^2}=a\)

Now, we will determine the final velocity of the movement. We will use the following equation of motion:

\(2ad=v^2_f-v^2_0\)

Since the box starts from rest this means that the initial velocity is zero:

\(2ad=v^2_f\)

Now we take the square root to both sides:

\(\sqrt[]{2ad}=v_f\)

Now we substitute the values:

\(\sqrt[]{2(1.779\frac{m}{s^2})(3.37m)}=v_f\)

Solving the operations:

\(3.46\frac{m}{s}=v_f\)

Now we use the following equation of motion to determine the time:

\(v_f=v_0+at\)

Since the initial velocity is zero:

\(v_f=at\)

Now we divide by the acceleration:

\(\frac{v_f}{a}=t\)

Substituting the values:

\(\frac{3.46\frac{m}{s}}{1.779\frac{m}{s^2}}=t\)

Solving the operations:

\(1.94s=t\)

Therefore, it takes the box 1.94 seconds to move.

What is projectile motion?

When a particle is thrown obliquely near the earth’s surface, it moves along a curved path under constant acceleration directed towards the center of the earth. The path of such a particle is called a projectile, and the motion is called projectile motion.

Given,

initial speed v = 4.4 m/s

Angle of projection θ = 15°

Height from the floor y = 0.70 m

Equation of trajectory:

y = x tanθ +/- gx²/2v²(cosθ)²

where

y is the vertical distance

x is the horizontal distance

θ is the angle of projection

g is 9.8 m/s²

v is the initial velocity

Since the angle is below horizontal, vertical displacement would be negative.

Substituting the values:

- 0.8 = xtan15° - (9.8)x²/[2(4.4)²(cos15°)²]

Solving for x,

- 0.8 = x(0.268) - (9.8)x²/[2(4.4)²(0.966)²]

- 0.8 = x(0.268) - (9.8)x²/[2(4.4)²(0.966)²]

- 0.8 = x(0.268) - (9.8)x²/36.1318

- 0.8 = x(0.268) - 0.27 x²

0.27x² - 0.268x - 0.8 = 0

Solving the quadratic equation,

x = 2.29

x = - 1.30

Distance should be positive.

Hence, ball covered 2.29 m horizontal distance before bouncing.

Water flows through a pipe ofradius 0.0250 m at 1.50 m/s.What is the Volume Flow Rate?(Keep 3 sig figs.)(Unit=m^3/s)Help

Answers

The volume flow rate (Q) of water through a pipe can be calculated using the formula:

Q = A * v

where A is the cross-sectional area of the pipe and v is the velocity of water.

The cross-sectional area of the pipe can be calculated using the formula for the area of a circle:

A = πr^2

where r is the radius of the pipe.

Substituting the given values, we get:

r = 0.0250 m
A = π(0.0250 m)^2 = 0.0019635 m^2
v = 1.50 m/s

Now, we can calculate the volume flow rate:

Q = A * v = 0.0019635 m^2 * 1.50 m/s = 0.002944 m^3/s

Rounding off to 3 significant figures, the volume flow rate is 0.00294 m^3/s.

Both carts start from rest, their change in momentum will be equal to their final momentum. according to newton's second law, the same force applied to the two carts results in for the plastic cart compared to the lead cart, which means the plastic cart will travel the distance of 1 m in time interval compared to the lead cart. therefore, from the momentum principle the plastic cart will have final momentum, compared to the lead cart.

Answers

The impulses and changes in momentum are identical because equal forces are applied over equal periods of time.

The momenta of the two carts are identical since they both begin at rest and experience equal changes in momentum. We are aware that force is the same as mass multiplied by acceleration. Due to the initial resting state of both carts, u = 0 m/s, and the plastic cart moves 1 m. Newton's second law states that when the same force is applied to the two carts, the plastic cart will have more final momentum than the lead cart because of the momentum principle.

Answers

A projectile is an object thrown into the air and subject only to gravity and, if applicable, air resistance. The time taken by disc C to reach its maximum height is approximately 1.53 seconds, and its maximum height above the ground is around 11.48 meters. The time from when disc C was thrown upwards until ball B hits the disc is roughly 1.29 seconds.

3.1 Explanation of the term projectile:

A projectile refers to an object that is launched or thrown into the air and is subject only to the forces of gravity and air resistance (if applicable). The motion of a projectile can be analyzed independently of its mass, shape, or any other physical property. The key characteristic of a projectile is that it follows a curved path known as a trajectory.

When a projectile is launched, it moves along a parabolic trajectory due to the combination of its initial velocity and the force of gravity acting vertically downward. The horizontal motion of a projectile remains constant and unaffected by gravity, while the vertical motion is influenced by the acceleration due to gravity.

The path of a projectile can be described mathematically by considering its initial velocity, angle of projection, and the acceleration due to gravity. Projectile motion finds applications in various fields, such as sports, engineering, and physics, where objects are launched or thrown.

3.2.1 Time taken by disc C to reach its maximum height:

To determine the time taken by disc C to reach its maximum height, we can use the kinematic equation for vertical motion. The equation is:

vf = vi + at

Where:

vf = final velocity (which is zero at the maximum height)

vi = initial velocity

a = acceleration (in this case, acceleration due to gravity, -9.8 m/s²)

t = time

Since the disc is thrown vertically upwards, its initial velocity is 15 m/s. We want to find the time it takes for the disc to reach its maximum height, so we'll use the equation and solve for time (t):

0 = 15 + (-9.8)t

Rearranging the equation, we get:

9.8t = 15

t = 15 / 9.8

Calculating this, we find:

t ≈ 1.53 seconds

Therefore, it takes approximately 1.53 seconds for disc C to reach its maximum height.

3.2.2 Maximum height above the ground reached by disc C:

To determine the maximum height reached by disc C, we can use another kinematic equation for vertical motion:

vf² = vi² + 2ad

Where:

vf = final velocity (which is zero at the maximum height)

vi = initial velocity

a = acceleration (in this case, acceleration due to gravity, -9.8 m/s²)

d = displacement (maximum height)

Since we know the initial velocity (vi) and acceleration (a), we can solve for the displacement (d), which represents the maximum height:

0² = 15² + 2(-9.8)d

Rearranging the equation, we get:

0 = 225 - 19.6d

19.6d = 225

d = 225 / 19.6

Calculating this, we find:

d ≈ 11.48 meters

Therefore, the disc C reaches a maximum height of approximately 11.48 meters above the ground.

Calculating the time from the moment that disc C was thrown upwards until the time ball B hits the disc:

To find the time it takes for ball B to hit disc C, we need to calculate the time it takes for both objects to reach the same height.

Since disc C was thrown upwards from the edge of the roof and ball B was shot vertically upwards from the foot of the building, we need to consider the additional height of the building (30 meters).

The time it takes for disc C to reach the ground is the same as the time it takes for ball B to reach a height of 30 meters above the ground.

Using the kinematic equation for vertical motion, we can calculate the time for ball B:

d = vit + 0.5at²

Where:

d = displacement (30 meters)

vi = initial velocity (40 m/s)

a = acceleration (acceleration due to gravity, -9.8 m/s²)

t = time

30 = 40t + 0.5(-9.8)t²

Rearranging the equation, we get:

4.9t² + 40t - 30 = 0

Solving this quadratic equation, we find:

t ≈ 1.29 seconds or t ≈ -5.82 seconds

Since time cannot be negative in this context, we discard the negative solution.

Therefore, it takes approximately 1.29 seconds from the moment that disc C was thrown upwards until ball B hits the disc.

Answers

The correct answer is To calculate the tangential acceleration of the inner surface of the exercise wheel, we first need to determine the angular acceleration of the wheel. We can use the formula for angular acceleration:

alpha = (omega_f - omega_i) / t where alpha is the angular acceleration, omega_f is the final angular velocity, omega_i is the initial angular velocity, and t is the time interval. We know that the hamster starts at rest, so the initial angular velocity is zero. We also know that the final angular velocity is 2πf, where f is the rotational frequency in hertz. In this case, the final angular velocity is: omega_f = 2πf = 2π(1.00 Hz) = 6.28 rad/s The time interval is given as 0.800 s. Therefore, we can plug in the values and solve for the angular acceleration: alpha = (6.28 rad/s - 0 rad/s) / 0.800 s alpha = \(7.85 rad/s^2\)Next, we can use the formula for tangential acceleration: a_tan = r * alpha

Electric fields are created by a difference in electric potential, which is measured in volts. When a voltage is applied to a set of parallel plates, the charges within the plates will be affected by the electric field, and will move in response to it.

What are electric parallel plates?

When a voltage is applied to a set of parallel plates, the positive charges in the plate connected to the positive voltage will be attracted to the negative voltage, while the negative charges in the plate connected to the negative voltage will be attracted to the positive voltage.

The movement of charges between the plates is also affected by the presence of any obstacles or resistances in the electric field, such as resistance in the wire. This can slow down the movement of charges and result in a decrease in the current flowing through the circuit.

The low-frequency speaker of a stereo set produces 10.0 W of acoustical power. If the speaker projects sound uniformly in all directions, at what distance from the speaker is the intensity level 80.0 dB

Answers

Answer:

the required distance is 89.125 m

Explanation:

Given the data in the question;

we know that, sound intensity B in decibels of sound is;

β(dB) = 10log₁₀( \(I\) / \(I_0\) )

where intensity \(I\) = power / area carried by wave

\(I_0\) = 10⁻¹² W/m² { minimum threshold intensity }

Now,

intensity \(I\) = power / area carried by wave = P/A = P/4πr² { spherical  }

given that; β = 80.0 dB and P = 10 W

so

β(dB) = 10log₁₀( \(I\) / \(I_0\) )

we substitute

80 = 10log₁₀( P / 4πr²× \(I_0\))

80 = 10log₁₀( 10 / 4πr²× 10⁻¹² )

8 = log₁₀(10) - log₁₀( 4πr²× 10⁻¹² )  

8 = 1 - log₁₀( 4πr²× 10⁻¹² )

8 - 1 = -log₁₀( 4πr²× 10⁻¹² )

7 = -log₁₀( 1.2566 × 10⁻¹¹ × r² )

7 = -[ log₁₀( 1.25 × 10⁻¹¹) + log₁₀( r² ) ]

7 = -[ -10.9 + log₁₀( r² ) ]

7 = 10.9 - log₁₀( r² )

-log₁₀( r² ) = 7 - 10.9

-log₁₀( r² )  = - 3.9

log₁₀( r² ) = 3.9

2log₁₀r = 3.9

log₁₀r  = 3.9 /2

log₁₀r = 1.95

r = 89.125 m

Therefore, the required distance is 89.125 m

When are zeros significant when found to the trailing (to the right) of the decimal point?

Answers

Answer:

Usually, zeroes are found to the right of a decimal point in significant numbers if you have something like \(7\frac{1}{100000000000000000000000000}\) (exaggerated example of course), which is when you have a number that is very very close to the integer before it, but isn't that integer.

What is the magnitude of the resultant vector? Round your answer to the nearest tenth. m

Answers

The magnitude of the resultant vector to round the answer to the nearest tenth, we look at the digit in the hundredth's place. If this digit is 5 or greater, we round up. If it is less than 5, we round down.

In the study of physics, we use vectors to represent quantities that have both direction and magnitude. It is often the case that we want to add two or more vectors together to obtain a single vector that represents the net result of these additions. The process of adding two or more vectors together is known as vector addition.The magnitude of the resultant vector is the length of the line that represents it on a scale drawing.

When we add two or more vectors together, the resultant vector is the vector that represents the net result of these additions. To find the magnitude of the resultant vector, we use the Pythagorean theorem, which states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.

In the case of vector addition, the hypotenuse is the resultant vector, and the other two sides are the component vectors. If we have two vectors a and b, the magnitude of the resultant vector is given by the following equation:|R| = √(ax2 + bx2)where R is the resultant vector, a and b are the component vectors, and x is the angle between the vectors.

For example, if the answer is 12.345, we would round it to 12.3.
