The gravitational force of the satellite can be determined using universal gravitational law. The force of gravitation on the satellite is 6.73 × 10⁻²⁵ N.

Gravitational force is a kind of force by which an object attracts other objects into its centre of mass. Earth gravitationally pull every objects into its centre and that's why every one is standing on the ground.

According to Universal Gravitational law, the force of gravitation g is written as:

g = G m/r²

where, G is the universal gravitational constant and   r be the distance from the surface and m be the mass.

The mass of the satellite = 2190 Kg

r = 465650 × 10³ m

G = 6.67 × 10⁻¹¹ m³/ Kg s⁻²

then g = 6.67 × 10⁻¹¹ m³/ Kg s⁻² ×  2190 Kg/ (465650 × 10³ m)²

           = 6.73 × 10⁻²⁵ N.

Therefore, the gravitational force on the satellite is 6.73 × 10⁻²⁵ N.

Answer:

1) Constants are variables that are kept the same throughout an experiment.

2) An independent variable is a variable that is manipulated by the experimenter.

3) A dependent variable is a variable that is measured by the experimenter.

Explanation:

Assuming that air resistance is neglected, both the ping pong ball and the bowling ball will hit the ground at the same time.

This is because, according to the laws of physics, the acceleration of an object due to gravity is independent of its mass. Both the ping pong ball and the bowling ball will experience the same acceleration due to gravity as they fall, which is approximately 9.8 meters per second squared (9.8 m/s^2) near the surface of the Earth.

Since the acceleration due to gravity is the same for both balls, they will both accelerate at the same rate and therefore reach the ground at the same time, neglecting air resistance.

It's worth noting that in the presence of air resistance, the balls would experience a drag force that would slow them down and cause them to fall at different rates. However, if air resistance is neglected as stated in the question, then both balls will hit the ground at the same time.

The electric field at a point halfway is 18.37 x 10⁵ N/C.

We need to know about the electric fields to solve this problem. The electric field produced by a single-point positive charge is a radial field, whose strength is given by the equation

E = k.Q/r²

where E is the electric field, Q is the charge and r is the radius.

From the question above, we know that

k = 9 x 10⁹ Nm²/C²

Q1 = -5μC = -5 x 10¯⁶ C

Q2 = 4μC = 4 x 10¯⁶ C

Explanation:

Upon calculations, the solution was found to be that the centrifuge rotor will make approximately 5,579 revolutions before coming to rest, and it will take about 32.4 seconds for it to do so.

The centrifuge rotor, with a mass of 4.8 kg and approximated as a solid cylinder of radius 0.0710 m, is initially rotating at 10,300 rpm. It comes to rest due to a frictional torque of 1.2 m*N acting on it.

To determine the number of revolutions the rotor will make before coming to rest and the time it will take, we can use the principles of rotational dynamics.

The initial angular velocity of the rotor can be calculated by converting the given 10,300 rpm to rad/s: 10,300 rpm = (10,300 rev/min) * (2π rad/rev) * (1 min/60 s) ≈ 1,080 rad/s.

The frictional torque acting on the rotor can be related to the angular acceleration through the equation τ = Iα, where τ is the torque, I is the moment of inertia, and α is the angular acceleration.

In this case, the torque is 1.2 m*N, and the moment of inertia for a solid cylinder is given by I = ½ * m * r^2, where m is the mass and r is the radius.

Rearranging the equation τ = Iα, we can solve for α: α = τ / I. Substituting the given values, we find α = 1.2 m*N / (½ * 4.8 kg * (0.0710 m)^2) ≈ 33.3 rad/s^2.

The final angular velocity of the rotor is zero since it comes to rest.

Using the equation ω = ω₀ + αt, where ω is the final angular velocity, ω₀ is the initial angular velocity, α is the angular acceleration, and t is the time, we can solve for t: 0 = 1,080 rad/s + (-33.3 rad/s^2) * t.

Rearranging the equation, we find t ≈ 32.4 s.

The number of revolutions can be calculated by dividing the initial angular displacement by 2π.

The initial angular displacement can be obtained by multiplying the initial angular velocity by the time: θ = ω₀ * t. Substituting the given values, we have θ = 1,080 rad/s * 32.4 s ≈ 35,088 rad.

Finally, the number of revolutions is given by the equation N = θ / (2π), where N is the number of revolutions: N ≈ 35,088 rad / (2π rad/rev) ≈ 5,579 revolutions.

Therefore, the centrifuge rotor will make approximately 5,579 revolutions before coming to rest, and it will take about 32.4 seconds for it to do so.

A 5N solution is first diluted at a ratio of 1:4, and then the resulting solution is further diluted at a ratio of 4:15.      The question asks for the concentration in normality of the final solution.

Normality (N) is a measure of the concentration of a solution and is defined as the number of gram equivalents of solute per liter of solution. To determine the concentration in normality of the final solution, we need to calculate the gram equivalents of solute in the solution.

In the first dilution, the 5N solution is diluted at a ratio of 1:4. This means that for every 1 part of the original solution, 4 parts of the diluent (usually water) are added.     As a result, the concentration of the solution is reduced by a factor of 4.

Next, the resulting solution is diluted at a ratio of 4:15. This means that for every 4 parts of the solution, 15 parts of the diluent are added. This further reduces the concentration of the solution.

The final concentration in normality, we need to determine the gram equivalents of solute in the final solution. This can be done by multiplying the initial concentration (5N) by the dilution factors (1/4 and 4/15) and dividing by the final volume of the solution.

Therefore, by considering the dilution ratios and using the concept of normality, we can calculate the concentration in normality of the final solution.

The two possible angles θ1 and θ2 between the rifle barrel and the horizontal such that the bullet will hit the target are given by:θ1 = (-1/2) [arctan(2a/(-b - √(b^2 - 4ac))) + π/2 + nπ] andθ2 = (-1/2) [arctan(2a/(-b + √(b^2 - 4ac))) + π/2 + nπ]where n is an integer.

In the given case, the figure shows an exaggerated view of a rifle that has been sighted in for a 91.4-meter target. Let the muzzle speed of the bullet be v0 = 427 m/s.

Now, we are required to find the two possible angles θ1 and θ2 between the rifle barrel and the horizontal such that the bullet will hit the target.

It is known that the horizontal displacement of the bullet from the gun can be given by the equation: x = v0 t cosθ ..........(i)and the vertical displacement of the bullet from the gun can be given by the equation: y = v0 t sinθ - (1/2) g t^2..........(ii).

Here, t is the time of flight of the bullet and g is the acceleration due to gravity.

As the bullet hits the target, its final vertical displacement from the gun is equal to the height of the target, i.e.,y = 91.4m.Now, we can substitute equations (i) and (ii) in place of t and y in equation (ii) to get:x tanθ - (g/2v0^2) x^2 sec^2θ = 91.4 ..........(iii)This is a quadratic equation in tanθ.

On solving this equation using the quadratic formula, we get:tanθ = [-b ± √(b^2 - 4ac)]/2aWhere,a = -gx^2/(2v0^2) = -4.9x^2/v0^2, b = x, and c = -91.4.

Rearranging the terms, we get:2a tanθ^2 + b tanθ - 91.4 = 0On substituting the given values, we get:2(-4.9x^2/v0^2) tanθ^2 + x tanθ - 91.4 = 0θ1 and θ2 are the two possible angles which can be found by solving the above quadratic equation.

Using the trigonometric identity given in the hint, we can write: sin 2θ = 2 sinθ cos θ = 2 tanθ/ (1 + tan^2θ)Now, we can substitute tanθ = (-b ± √(b^2 - 4ac))/2a in the above equation to get: sin 2θ = (-4bx ± 2x√(b^2 - 4ac))/(b^2 + 4a^2)Now, we can substitute the given values to get: sin 2θ1 = -0.999sin 2θ2 = 0.998.

Thus, we get two values of sin 2θ, one is close to -1 and the other is close to 1. As sin 2θ = -1 when 2θ = -π/2 + nπ and sin 2θ = 1 when 2θ = π/2 + nπ, where n is an integer, we get two possible values of θ for each of these two cases.

Hence, the two possible angles θ1 and θ2 between the rifle barrel and the horizontal such that the bullet will hit the target are given by:θ1 = (-1/2) [arctan(2a/(-b - √(b^2 - 4ac))) + π/2 + nπ] andθ2 = (-1/2) [arctan(2a/(-b + √(b^2 - 4ac))) + π/2 + nπ]where n is an integer.

Explanation:

Answer: negative

Explanation:

The statement "For a symmetric laminate, the uniform temperature change will not produce thermal moment resultants" is true.

A laminate is symmetric when its layer stacking sequence is such that the layers on one side of the laminate are a mirror image of the layers on the other side. When a symmetric laminate is subjected to a uniform temperature change, the layers on both sides of the laminate experience the same amount of thermal expansion or contraction. As a result, the laminate does not undergo any twisting or warping, and there is no tendency for the laminate to rotate or move due to thermal expansion.

This means that the thermal moment resultants, which are the moments that arise due to the thermal expansion or contraction of a material, are zero for a symmetric laminate subjected to a uniform temperature change. The absence of thermal moment resultants is a desirable property for many engineering applications, as it reduces the risk of distortion or failure due to temperature changes.

In summary, a symmetric laminate subjected to a uniform temperature change does not produce thermal moment resultants, making this statement true.

The driver experiences about 0.835 g, g-force during the acceleration. and the car travels about 49.8 meters (163 feet) to hit 60 mph.

What is g-force?

To calculate the g-force experienced by the driver during the acceleration, we need to use the formula:

g-force = acceleration due to gravity / acceleration of the car

The acceleration due to gravity is approximately 9.81 m/s², or 32.2 ft/s².

The acceleration of the car can be calculated by converting the acceleration from 0-60 mph to meters per second squared (m/s²). We can use the following formula to convert:

a = (v_f - v_i) / t

where:

a = acceleration

v_f = final velocity (60 mph in this case, which is 26.8 m/s)

v_i = initial velocity (0 mph in this case, which is 0 m/s)

t = time taken to reach final velocity (2.28 seconds in this case)

Plugging in the values, we get:

a = (26.8 m/s - 0 m/s) / 2.28 s

a ≈ 11.75 m/s²

Now we can calculate the g-force experienced by the driver:

g-force = 9.81 m/s² / 11.75 m/s²

g-force ≈ 0.835 g

Therefore, the driver experiences about 0.835 g during the acceleration.

To calculate the distance traveled by the car to hit 60 mph, we can use the following formula:

d = v_i * t + 0.5 * a * t²

where:

d = distance traveled

v_i = initial velocity (0 mph in this case, which is 0 m/s)

t = time taken to reach final velocity (2.28 seconds in this case)

a = acceleration (11.75 m/s²)

Plugging in the values, we get:

d = 0 m/s * 2.28 s + 0.5 * 11.75 m/s² * (2.28 s)²

d ≈ 49.8 m

Therefore, the car travels about 49.8 meters (163 feet) to hit 60 mph.

Given, Angela has a bucket of mass 2 kg tied to a string. She places a drinking glass of mass 0.5 kg in the bucket. She spins the bucket in a vertical circle of radius 1.5 m. She must swing the bucket to keep the glass from falling out.

a. The free body diagram of the bucket and glass is attached below.

b. Bucket will undergo centrifugal force

Fb = mVtop² /R

From the equilibrium of forces, we have

For bucket,

T +mb xg - N = mb x Vtop² /R..............(1)

For glass,

mg x g + N = mg x Vtop² /R..............(2)

Thus, this is the net force equation on the glass.

c. On adding both the equations. we have

T + (mb + mg) xg = (mb + mg) Vtop² /R

Substituting the values, T = 0 and from the question, we get

0 + (2+0.5) 9.81 = (2+0.5)(Vtop²/0.5)

Vtop = 3.83 m/s

Thus, the speed of spin to prevent glass from falling out is 3.83 m/s

d. The string will break if the tension on it is more than 100 N

100 + (2+0.5) 9.81 = (2+0.5)(Vtop²/0.5)
