In order to calculate the potential energy of an object, we can use the formula below:

Where PE is the potential energy (in Joules), m is the mass (in kg), g is the gravity acceleration (in m/s²) and h is the height (in meters).

Since mass times gravity is equal to the weight force, we can also write the formula as follows:

Where W is the weight force (in Newtons).

So the formula will be:

Potential Energy = Weight x Height

Since the height is equal to 1.5 meters and the weight force is equal to 5 N, we have:

The potential energy is 7.5 Joules.

When you decrease the distance to the nut, the lever arm also decreases. Hence the correct option is "It decreases".

This is because the lever arm is the perpendicular distance between the axis of rotation and the line of action of the force. In this case, the axis of rotation is the nut and the force is applied at a point closer to the nut. As the distance between the force and the nut decreases, the lever arm also decreases.

This relationship between distance and lever arm is important in understanding how levers work. A longer lever arm allows for greater torque or rotational force to be applied with the same amount of force. Conversely, a shorter lever arm requires more force to generate the same amount of torque. By decreasing the distance to the nut, you are effectively shortening the lever arm and therefore reducing the torque that can be applied.

Understanding the relationship between distance and lever arm can be useful in a variety of contexts, such as in engineering, physics, and even sports. It can help in designing more efficient machines or in understanding how to optimize physical movements for maximum performance.

An example of the law of conservation of energy is a roller coaster.

The law of conservation of energy states that energy cannot be created or destroyed, only transferred or transformed from one form to another. This means that the total amount of energy in a closed system remains constant over time.

A roller coaster car gains kinetic energy as it moves down the track, but it also loses potential energy. At the bottom of the track, the car has the most kinetic energy and the least potential energy, while at the top of the track, it has the most potential energy and the least kinetic energy.

The momentum of the small rock at distance 2 is 1.08e+17 kg · m/s, in the -y direction.

What is momentum?

To solve this problem, we need to use the conservation of momentum. Since there are no other massive objects nearby, the total momentum of the system (rock + star) must be conserved.

At the first distance d1, the momentum of the rock can be split into two components: one in the x direction and one in the y direction. Using the angle α = 122 degrees, we can calculate the x and y components of the momentum:

p1x = p1 * cos(α) = 1.15e+17 kg · m/s * cos(122°) = -3.97e+16 kg · m/s

p1y = p1 * sin(α) = 1.15e+17 kg · m/s * sin(122°) = 1.08e+17 kg · m/s

Since there are no external forces acting on the system, the momentum in the x direction and the momentum in the y direction must be conserved separately. However, since the path of the rock is not given, we cannot assume that the momentum in the x direction is conserved. Therefore, we need to calculate the new momentum of the rock in the y direction at distance d2.

To do this, we can use the conservation of momentum in the y direction:

p1y = p2y

where p2y is the momentum of the rock in the y direction at distance d2.

We can rearrange this equation to solve for p2y:

p2y = p1y = 1.08e+17 kg · m/s

Therefore, the momentum of the small rock at distance 2 is 1.08e+17 kg · m/s, in the -y direction.

The terminal velocity is B. V-U = mg D.

Terminal velocity is the constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration. This occurs when the gravitational force pulling the object downward is balanced by the opposing force of air resistance or other fluid resistance acting in the opposite direction. At terminal velocity, the net force acting on the object becomes zero, and the object continues to fall at a constant speed without any further acceleration.

The terminal velocity of an object depends on its mass, shape, and surface area as well as the density and viscosity of the fluid it is falling through

When a body of mass m falls through a liquid, it experiences a viscous force (V) and an upthrust force (U) in addition to its weight (mg). At terminal velocity, the net force on the body becomes zero, so:

V + U + mg = 0

Rearranging this equation, we can solve for the terminal velocity (V):

V = -U - mg

Therefore, the correct answer is option B: V-U = mg.

A total of 70 joules of work is done when a 35-newton force lifts a crate to a loading dock 2 meters high.

The amount of work done can be calculated using the formula:

work = force x distance x cos(theta)

where force is the applied force, distance is the distance moved in the direction of the force, and theta is the angle between the force vector and the displacement vector.

In this scenario, the force is 35 newtons, the distance is 2 meters (the height the crate is lifted), and the angle between the force vector and the displacement vector is 0 degrees (because  the force is directly upwards and the displacement is also upwards).

Therefore, cos(Ф) = 1.

Substituting  in these values, we get:

work = 35 newtons x 2 meters x 1

Which one of the following conclusions is correct concerning the magnitudes of the forces mentioned above?

A) Force 1 exceeds force 2.

B) Force 2 is less than force 3.

C) Force 2 exceeds force 4.

D) Force 3 exceeds force 4.

E) Forces 1 and 2 cannot have equal magnitudes.

Answer: B) Force 2 is less than force 3.

Explanation: From the given four forces to be considered, Force 2 is less than Force 3 is correct option.

After evaluating the forces one by one. Force 3 and Force 4 are the same, both have equal magnitude.

And Force 3 is greater than Force 2, i.e., the force of the horse pushing on the road is much higher than the cart pulling the horse. Hence, more forces is required to pull the cart while on the road towards forward direction.

More so, the force of the road pushing on the horse is greater than the force of the cart pulling on the horse.

To determine the number of half-lives that have elapsed, we need to compare the ratio of 14C to 14N atoms found in the hip bone fragment.

The ratio of 1 14C atom for every 31 14N atoms suggests that the hip bone fragment contains a smaller amount of 14C compared to the expected ratio found in a living organism. Since 14C undergoes radioactive decay with a half-life of approximately 5730 years, we can calculate the number of half-lives that have elapsed by observing how many times the ratio needs to double to reach the expected ratio.

In this case, if the expected ratio is 1:1, then the observed ratio of 1:31 would require five doublings to reach 1:1. Therefore, approximately five half-lives have elapsed since the death of the organism from which the hip bone fragment originated.

average acceleration, a = (2.8 - 0)/2.5 = 1.12 m/s². So, the acceleration during this time interval is 1.12 m/s² .The acceleration during this time interval is 1.12 m/s².

Velocity is the derivative of displacement, and acceleration is the derivative of velocity.

As a result, to find acceleration, we need to find the rate of change of velocity or the derivative of velocity.

We can calculate the average acceleration using the velocity and the time interval.

The formula for average acceleration is:

a = (vf - vi)/t

where vf is the final velocity

vi is the initial velocity,

and t is the time interval.

Given, x = 8.0 m, t = 2.5 s, and vf = 2.8 m/s.

We can assume that the initial velocity,

vi, is zero (because no initial velocity is given).

Therefore, a = (2.8 - 0)/2.5 = 1.12 m/s².
