You are riding a bicycle. If you apply a forward force of 172 N, and you and the bicycle have a combined mass of 51 kg, what will be the forward acceleration of the bicycle? (Assume there is no friction)​

The formula equivalent to D=m/V is V=m/D.

The mass of a substance per unit of volume is referred to as density. This is represented in the formula as, D=m/V.

Here, D is density, m is mass, and V is the volume. To find which formula is equivalent to this formula, we have to follow the below steps.

Since V is present on left in all the given options. So let's take V as the subject of the formula.

By doing so, bring V to the left side of the density formula. Therefore,

VD=m

To eliminate D on the left side, divide both sides by D. We get,

\(\begin{aligned}\frac{VD}{D}&=\frac{m}{D}\\V&=\frac{m}{D}\end{aligned}\)

So, the correct option is A.) V=m/D.

The complete question is -

Which formula is equivalent to D = m/V?

A.) V= m/D

Answer:

A. primary waves

Explanation:

When a same-sized force is applied over a smaller area, the pressure increases.

Pressure is defined as the force acting per unit area (P = F/A). Here, F represents the force and A represents the area. When the area (A) decreases, and the force (F) remains constant, the overall pressure (P) increases according to the formula.

This concept can be easily understood by imagining a person standing on the ground wearing regular shoes versus standing on the ground wearing high heels. In both cases, the person's weight (force) remains the same, but the area of contact with the ground is much smaller with high heels. As a result, the pressure exerted on the ground by high heels is much higher than that of regular shoes.

Understanding the relationship between force, area, and pressure is crucial in various applications, such as hydraulic systems, pneumatic systems, and even in our daily lives. Increasing pressure by reducing the area can enhance the efficiency of certain processes while decreasing pressure by increasing the area can help distribute force more evenly and reduce potential damage or stress on surfaces.

Lake Mead, the reservoir above the Hoover Dam, has a surface area of approximately 640 km2, so here is the gravitational potential energy of the top 1 meter of water in Lake Mead: 1.42 x \(10^1^7\) J.

Here the calculation for the gravitational potential energy is given below,  

PE = m × g × h

Here,  m = density of water × volume of water                    

m= 1000 kg/\(m^3\) × 640 \(km^2\)× 1 m

m= 640,000,000,000 kg

PE = 640,000,000,000 kg * 9.8 m/\(s^2\) * 220 m

PE= 1.42 x\(10^1^7\) J

Hence, Lake Mead, the reservoir above the Hoover Dam, has a surface area of approximately 640 km2, so here is the gravitational potential energy of the top 1 meter of water in Lake Mead: 1.42 x \(10^1^7\) J.

Water will not flow out of the trench without pumping.

To determine if water will flow out of the trench without pumping, we need to compare the hydraulic head in the aquifer at the trench with the hydraulic head in the river. The hydraulic head is the potential energy of the water and is given by the elevation head (z) and the pressure head (h):

Hydraulic head = z + h

- Hydraulic conductivity of the aquifer (K) = 0.1 ft/day

- Aquifer thickness (d) = 20 ft

- Water depth in the river (H_river) = 20 ft

- Bottom of the trench below river bottom (B_trench) = 30 ft

- Distance from edge of river to trench (L) = 600 ft

- Depth of the trench (D_trench) = 40 ft

First, we need to calculate the hydraulic head in the aquifer at the trench. The elevation head (z) is the difference in elevation between the bottom of the trench and the river bottom:

Elevation head (z) = B_trench - H_river

z = 30 ft - 20 ft

z = 10 ft

Next, we need to calculate the pressure head (h) in the aquifer at the trench using Darcy's law:

h = (K / d) * L

Substituting the given values:

h = (0.1 ft/day / 20 ft) * 600 ft

h = 3 ft

Now, we can calculate the hydraulic head in the aquifer at the trench:

Hydraulic head in the aquifer at the trench = z + h

Hydraulic head = 10 ft + 3 ft

Hydraulic head = 13 ft

Finally, we compare the hydraulic head in the aquifer at the trench with the hydraulic head in the river. If the hydraulic head in the aquifer is higher, water will flow out of the trench without pumping.

In this case, since the hydraulic head in the aquifer (13 ft) is lower than the water depth in the river (20 ft), water will not flow out of the trench without pumping.

Therefore, water will not flow out of the trench without pumping.

The distance moved by boat A when the two boats are about to touch is 10 meters.

To solve this problem, we can use the principle of conservation of momentum. Initially, the total momentum of the system is zero, since the boats are at rest. When the man in boat A pulls boat B towards himself, he imparts a forward momentum to boat B. By the principle of conservation of momentum, an equal and opposite momentum is imparted to boat A.

We can use the equation:

m1v1 + m2v2 = (m1 + m2)v'

where m1 and v1 are the mass and velocity of boat A initially, m2 and v2 are the mass and velocity of boat B initially, and v' is the final velocity of both boats when they are about to touch.

Plugging in the given values, we get:

(400 kg)(0 m/s) + (400 kg)(0 m/s) = (400 kg + 400 kg)v'

v' = 0 m/s

This tells us that the final velocity of both boats is zero. We also know that the man in boat A pulls boat B a distance of 30 meters. Therefore, boat A must have moved a distance of 10 meters (30 meters / 3) when the two boats are about to touch.

The non-conservative work done on the boy is 1.34569 kJ.

Non-conservative work is work done on an object by a force that depends on the path taken between the initial and final positions. To find the non conservative work done on the boy, we need to calculate the change in his mechanical energy due to non conservative forces. The mechanical energy of the boy is the sum of his kinetic energy and potential energy:

E = K + U

where K is the kinetic energy and U is the potential energy.

At the start of the wave, the boy has only kinetic energy, which we can calculate as:

K1 = \(0.5 * m * v1^2\)

= \(0.5 * 69.3 kg * (1.60 m/s)^2\)

= 88.96 J

where m is the mass of the boy and v1 is his initial speed.

When he drops through a height of 1.58 m, he loses potential energy equal to:

U1 - U2 = m * g * h

= \(69.3 kg * 9.81 m/s^2 * 1.58 m\)

= 1059.18 J

where g is the acceleration due to gravity and h is the height of the drop.

At the end of the drop, the boy has both kinetic and potential energy, which we can calculate as:

K2 = \(0.5 * m * v2^2\)

= \(0.5 * 69.3 kg * (8.51 m/s)^2\)

= 2493.83 J

U2 = m * g * h

= \(69.3 kg * 9.81 m/s^2 * 0\)

= 0 J

where v2 is his final speed.

Therefore, the initial mechanical energy of the boy is:

E1 = K1 + U1

= 88.96 J + 1059.18 J

= 1148.14 J

The final mechanical energy of the boy is:

E2 = K2 + U2

= 2493.83 J + 0 J

= 2493.83 J

The change in mechanical energy is:

ΔE = E2 - E1

= 2493.83 J - 1148.14 J

= 1345.69 J

This represents the work done on the boy by non conservative forces, so we can convert it to kilojoules:

ΔE = 1.34569 kJ

Therefore, the non conservative work done on the boy is 1.34569 kJ.

Answer;

Newton's laws models the motion of a body perfectly well.

The knowledge of the force acting on a body gives a good grasp of the resulting  motion.

There are three know laws of motion postulated by Newton;

 1st law; it states that an object will remain in its state of rest or uniform motion unless if it is acted upon by an external force.

 2nd law: it states that the acceleration of a body depends on the mass and force acting on it.

3rd law: it states that action and reaction are equal and opposite.

A sound understanding of these law's can help predict and model the motion of a body .

The work done on the lever by the input force is 1 J. Similarly the work done by the output force is 3 J. Here the output is greater than the input work which is not possible since all the energy given to the system cannot be converted as work done.

Work done is the product of force and displacement. When a force applied on a body is resulted in a displacement, the force is said to be done  work on the body.

Work done is a vector quantity and is characterized by a magnitude and direction. The force applied on the lever have to be 10 N over a distance of 0.1 m.

then work done = F. ds

w = 10 N × 0.1 m = 1 J

The output force = 1 N

distance = 3 m

work done by the body = 1 N × 3 m = 3 J

It is generally impossible to generate a machine with an efficiency of 100%. Thus output work done cannot be greater than the input work.

The line spacing you need for your diffraction grating is approximately 45454.55 lines/mm.

To calculate the line spacing you need for your diffraction grating in lines/mm, you can use the formula:

Line spacing (in mm) = 1 / (number of lines per mm)

Given that the screen is 10 meters away and the spacing between spots there should be 22 cm, we need to convert the screen distance and spot spacing to meters.

Screen distance = 10 meters
Spot spacing = 22 cm = 0.22 meters

Now, let's calculate the number of lines per meter by dividing the screen distance by the spot spacing:

Number of lines per meter = Screen distance / Spot spacing

Number of lines per meter = 10 meters / 0.22 meters = 45.45 lines/meter

To convert the number of lines per meter to lines per millimeter, we need to multiply it by 1000:

Number of lines per mm = Number of lines per meter * 1000

Number of lines per mm = 45.45 lines/meter * 1000 = 45454.55 lines/mm

The energy of a characteristic x-ray emitted from a tungsten target when an electron drops from an M shell (n=3 state) to a vacancy in the K shell (n=1 state) can be estimated using the equation E =hcZ²Δn²/n². Here Z is the atomic number for tungsten (Z=74) and Δn is the difference between n1, the initial orbital, and n2, the final orbital, (n1 - n2). In this case n1= 3 and n2= 1 giving (3-1=2).

Using the equation E =(hc*74²*2²)/1² = (6.63*10-34*.993*17576)/1= 1.36*10³ eV. Therefore, the estimated energy of the characteristic x-ray emitted from the tungsten target when an electron drops from the M shell (n=3) to a vacancy in the K shell (n=1) is approximately 1.36*10³ eV.
