The change in friction force experienced by the car is

The friction is caused between two uneven contacting surfaces.

When car is on ice, the friction force is

f = μ N

f₁ = 0.2 x 14500 = 2900N

When the car is on dry road, the friction force is

f₂ = 0.8 x 14500 =11,600 N

The change in friction force =11600 - 2900 = 8700N

Thus, the change in friction force experienced by the car is  8700N.

The claims of the healers are merely pseudoscience because we can not be able to back it empirically or reproduce the results.

In order to answer the question that is before us, we would have to look closely at the idea of science. We know that science depends on empiricism. This implies that we must be able to have verifiable and reproducible evidences for whatever proposition that is to be made in the field of science. This is a key fact that we must have in mind.

On the other hand, pseudoscience only depends on subjective views and principles that could be determined by individuals and is not independently verifiable by means of controlled experiments.

As such, the ideas of the healers are based on pseudo science because as we said, real science must be reproducible and the claims of the results independently verifiable but the results that is obtained by the healers dos not meet any of these criteria.

Answer:

ans is 16.66sec time is taken by runner

Answer:

The rock will rise H/6 units high on earth

Explanation:

In order to find the height to which rock rises, we use 3rd equation of motion. The 3rd equation of motion is as follows:

2gh = Vf² - Vi²

h = (Vf² - Vi²)/2g

where,

h = height

Vf = Final Velocity

Vi = Initial Velocity

g = acceleration due to gravity

ON MOON:

On moon:

h = H

Vf = 0 m/s (rock stops at highest point for a moment)

Vi = Vi

g = -(1/6) g (negative sign due to upward motion)

Therefore,

H = (0² - Vi²)/[-(2)(1/6)(g)]

H = 3Vi²/g

H/3 = Vi²/g  ------ equation (1)

ON EARTH:

On earth:

h = ?

Vf = 0 m/s (rock stops at highest point for a moment)

Vi = Vi (same initial velocity)

g = - g (negative sign due to upward motion)

Therefore,

h = (0² - Vi²)/(-2g)

h = Vi²/2g

h = (1/2)(Vi²/g)

using equation (1), we get:

h = (1/2)(H/3)

h = H/6

Two rocks are thrown directly upward with the same initial speeds is :

Part 1:

If the rock on the moon rises to a height H are :

                 2gh = Vf² - Vi²

                  h = (Vf² - Vi²)/2g

where,

Therefore,

The rock rise on the moon are H/3.

Part 2:

Therefore,

Using equation (1), we get:

The rock rise on the earth are H/6.

Two forces acting on the rocket immediately after leaving the launching pad are the gravitational force and the thrust force.

1. Gravitational Force: The gravitational force is the force exerted by the Earth on the rocket due to their mutual gravitational attraction. It acts downward and is responsible for the rocket's weight.

This force can be represented by the equation Fg = mg, where Fg is the gravitational force, m is the mass of the rocket, and g is the acceleration due to gravity. The gravitational force acts to pull the rocket downward, opposing its upward motion.

2. Thrust Force: The thrust force is the force generated by the rocket's engines as they expel exhaust gases in the opposite direction. It acts upward and propels the rocket forward.

The magnitude of the thrust force depends on factors such as the design of the rocket engines, the amount of fuel burned, and the rate of exhaust gas expulsion. The thrust force must be greater than or equal to the gravitational force for the rocket to overcome Earth's gravity and achieve upward acceleration.

Initially, when the rocket is launched, the thrust force is at its maximum while the gravitational force remains constant. As the rocket gains altitude, the gravitational force decreases slightly due to the increasing distance from the Earth's center.

However, the thrust force continues to be the dominant force propelling the rocket upward.

It's important to note that other forces such as air resistance and wind may also act on the rocket, but immediately after leaving the launching pad, these forces are typically negligible compared to the gravitational force and thrust force.

Explanation:

Option E is the correct answer.

When the asteroid strikes the space junk with a force not directed through its center of mass, it causes a net torque on the object, which results in both linear acceleration and rotational acceleration. As per Newton's second law, the net force and torque on the object will be proportional to its mass and moment of inertia, respectively.

Therefore, the piece of space junk will experience both linear acceleration and rotational acceleration, which means it will move linearly and spin simultaneously. The magnitude and direction of the linear and angular acceleration will depend on the direction and magnitude of the force and torque exerted by the asteroid.

A tank can be filled using pipes a, b, or both. it takes pipe a, working alone, 10 hours to fill the tank. it takes both pipes, working together, 9.9 hours to fill the tank. It take 9.8 hours pipe b working alone, to fill the tank.

We can do in this situation is figure out how long it takes both pipes to fill the tank on average.

So, we have:

Where T average = (tA + tB) / (2)

where

Where T aver = (tA + tB) / (2) average period (both pipes)

tA: duration of the pipe 

tb: the duration of pipe B.

Changing the values:

T average = (tA + tB) / (2)

We are physically surrounded with friction. An object moving along a path is resisted by a force known as static friction. Lastly, use an easy example to comprehend it. Think about the activity we perform frequently called walking. We are constantly in contact with the floor while we work. Motion presses against the ground as we move it backward, and we then advance our feet.

One key concept to be aware of in order to minimize friction is the fact that it operates in the opposite direction from relative motion. This phenomena may be useful for reducing the speed of the action until it eventually comes to a stop.

The child's speed at the lowest point is 5.42 m/s.

At the highest point of the swing, the child is momentarily at rest and has only potential energy. At the lowest point, the child has only kinetic energy.

Using the conservation of mechanical energy, we can write:

Potential energy at highest point = Kinetic energy at lowest point

mgh = (1/2)mv²

where m is the mass of the child, g is the acceleration due to gravity, h is the height of the swing at the highest point, and v is the speed of the child at the lowest point.

First, we need to find the height of the swing at the highest point. Since the swing is supported by two chains, the height of the swing at the highest point is half the length of the chains:

h = (1/2)3.00 m = 1.50 m

Next, we can solve for the child's speed at the lowest point:

mgh = (1/2)mv²

40.0 kg * 9.81 m/s² * 1.50 m = (1/2) * 40.0 kg * v²

Explanation:

Impulse and Momentum

The impulse-momentum theorem states that the change in momentum of an object equals the impulse applied to it.

The equation can be written as follows:

\(J =\Delta p = p_2-p_1\)

Where:

J    = Impulse

p2 = Final Momentum

p2 = Initial Momentum

The momentum can be calculated as:

p = m.v

Where m is the mass of the object and v is the velocity.

The tennis ball with mass m=60 g = 0.06 Kg was served from rest (v1=0) to v2=50 m/s. The change in momentum is:

\(\Delta p = 0.06Kg~50~m/s-0\)

\(\Delta p = 3~Kg.m/s\)

Thus the impulse is:

\(\marhbf{J = 3~Kg.m/s}\)

The density of the oil is 800 kg/m³.

The specific gravity of the cork in water is the fraction of the cork submerged in the water.

S.G = ³/₅ = 0.6

The density of the cork is calculated as follows;

\(S.G = \frac{\rho_c }{\rho_o} \\\\\rho_o = \frac{\rho_c }{S.G} \\\\\rho_o =\frac{600 \ kg/m^3}{0.75} \\\\\rho_o = 800 \ kg/m^3\)
