The magnitude of the force exerted on the man by the lawn mower is equal in magnitude to the force exerted by the man on the lawn mower, thus the answer is the third option i.e. the same.

Following are the three Newton's Law of Motion:

First Law - Newton’s first law of motion states that if a body or a object is at rest or moving at any constant speed in a straight line, it will remain at rest or keep moving in that straight line at that constant speed unless it is acted upon by a force. This law is known as Law of Inertia.

Second Law - Newton’s second law of motion is a quantitative description of the changes that any force can produce/insert on the motion of a body. It states that the timely rate of change of the linear momentum of a body is equal in both the magnitude and the direction to the force imposed on it.

Third Law - Newton’s third law of motion states that when two bodies interact, they both apply forces to one another that are equal in magnitude and opposite in direction. This third law of motion is also known as the law of action and reaction.

Using principles of third law of motion, we can make that the man pushing the lawn mower applies the same amount of force (in magnitude) as the lawn mower applies on him, thus the answer to the question is the third option i.e. the same.

The force responsible for the bouncing of the ball is the gravitational force.

According to Newton's law of universal gravitation, the gravitational force between any two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Gravity is the force with which objects are attracted to the earth. Example - Leaves and fruit fall from a tree to the ground due to gravity. Gravitational energy is the energy stored in an object due to its height above the Earth (for example, when the object is far from the ground or near it). It is a form of potential energy. An object's height above the ground gives it its gravitational energy. This force is responsible for the bouncing of the ball when it hits the ground.

The gravitational field strength on the surface of Ganymede is equal to 1.75 × 10^11 m/s^2. This is approximately 200 times the gravitational field strength of Earth.

Gravitational field is a region of space that is affected by the gravitational force of a massive object, such as a planet or star. It is the region in which any mass inside it experiences the force of gravity, and any mass outside of it does not. Gravitational fields can be measured in units called Newtons per kilogram (N/kg). The strength of the gravitational field is proportional to the mass of the object, with more massive objects creating stronger fields. In general, gravity is the weakest of the four fundamental forces, but it still has a profound effect on the behavior of matter and energy.

The gravitational field strength on the surface of Ganymede can be determined using Newton's law of gravity. According to this law, the force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Therefore, the gravitational field strength on the surface of Ganymede is equal to the gravitational force of Jupiter divided by the square of the distance between them.

The mass of Jupiter is 1.898 × 10^27 kg and the distance between Jupiter and Ganymede is 1.07 × 10^9 meters. Therefore, the gravitational field strength on the surface of Ganymede is equal to 1.75 × 10^11 m/s^2. This is approximately 200 times the gravitational field strength of Earth.

When two forces are applied in the same direction, we can use the vector addition to find the net force. The net force is found by adding the magnitudes of both forces.

In this case, the two forces are 225 N and 165 N, and they are applied in the same direction.

Therefore, the net horizontal force on the box is:

Net force = force 1 + force 2 = 225 N + 165 N = 390 N

This means that the net force acting on the box is 390 N when two horizontal forces, 225 N and 165 N, are exerted on the box in the same direction.

Time=0.9/2.998*10^8 is the equation for how long it takes light to travel 90 cm.

Velocity is the rate and direction of an object's movement, whereas speed is the time rate at which an object is moving along a path. In other words, velocity is a vector, whereas speed is a scalar value. the speed at which an object's position changes in any direction. The distance traveled in relation to the time it took to travel that distance is how speed is defined. The direction of a body or object's movement is defined by its velocity. In its basic form, speed is a scalar quantity. In essence, velocity is a vector quantity. It is the speed at which distance changes. It is the displacement change rate.

Here,

distance=90 cm=0.9 m

The spring's elastic potential energy decreases and the gravitational potential energy increases.

What do you mean by potential energy?

Potential energy is the energy an object possesses because of its position or state. It is the energy an object has due to its height, position, or chemical composition. The unit of measurement for potential energy is usually Joules (J).

There are different types of potential energy, such as gravitational potential energy (GPE), elastic potential energy (EPE), and chemical potential energy.

When a mass is attached to a vertical spring, it causes the spring to stretch. As the spring stretches, it stores potential energy in the form of elastic potential energy (EPE). As the spring stretches, the potential energy stored in it increases.

At the same time, as the mass is attached to the spring and moves downward, it loses gravitational potential energy (GPE) due to the work done by gravity on the mass. Since the mass is moving downward, the gravitational force is acting in the opposite direction of the displacement, resulting in a decrease in GPE. Therefore, as the mass moves downward, the EPE of the spring increases and the GPE of the mass decreases.

Therefore, the spring's elastic potential energy decreases and the gravitational potential energy increases.

Average power Pavg created by the force F is 48 watts, instantaneous power P at t = 10s is 480 watts.

To find the average power created by the force F, we can use the formula:

Pavg = (Work done by the force) / (time interval)

The work done by the force F can be found using the formula:

Work = force x distance

The distance is the displacement of the sled, which can be found using the formula:

distance = (initial velocity + final velocity) / 2 * time

The sled starts from rest, so its initial velocity is 0 m/s.

We know that the acceleration of the sled is 0.08 m/s^2 and the time is 1 minute, which is 60 seconds.

So the final velocity is:

final velocity = 0 + 0.08 m/s^2 x 60s = 4.8 m/s

We know that the force F is 600 N, so the work done by the force is:

Work = F x distance = 600 N x (4.8 m/s) = 2880 J

We know that the time interval is 1 minute, which is 60 seconds.

So the average power created by the force F is:

Pavg = Work / time interval = 2880 J / 60s = 48 watts (to 3 significant figures)

To find the instantaneous power P at t = 10s, we can use the formula:

P = F x v

where v is the velocity of the sled at time t.

We can find the velocity of the sled at time t using the formula:

v = v0 + a*t

where v0 is the initial velocity (0 m/s), a is the acceleration (0.08 m/s^2) and t is the time (10s)

so we can substitute v = v0 + a*t

v = 0 + 0.08 m/s^2 x 10s = 0.8 m/s

We know that the force F is 600 N, so the instantaneous power P created by the force F at t=10s is:

P = F x v = 600 N x 0.8 m/s = 480 watts (to 3 significant figures)

A projectile moves both vertically and horizontally independently of one another. Therefore, regardless of their horizontal velocities, two objects falling under the influence of gravity from the same height will hit the ground at the same time.

The vertical force acts perpendicular to the horizontal motion and has no effect on it because perpendicular components of motion are independent of one another. The projectile as a result moves with a decreasing vertical acceleration and a constant horizontal speed. The principle that horizontal and vertical motions are independent, or that they have no bearing on one another, is the most crucial one in projectile motion. The amount of time needed for an object to move initially horizontally is equal to the amount of time needed for the object to reach its final height. As a result, a ball dropped from the same height and thrown horizontally will both arrive at the ground simultaneously.

It is illegal to follow an emergency vehicle at a distance of less than 500 feet or to stop within 300 feet of where an emergency vehicle is responding to an alarm.

Maintaining a safe distance from an emergency vehicle enhances the safety of both the emergency vehicle's crew and other drivers on the road by providing the emergency vehicle with the necessary space to maneuver and respond quickly to an alarm. When an emergency vehicle is responding to an alarm, it may need to make sudden stops, turns or change speed quickly, and if the vehicle behind is too close, it may not be able to react in time and cause an accident. By maintaining a safe distance, other drivers can react in a timely manner to the emergency vehicle's movements, reducing the risk of collisions and accidents. Additionally, maintaining a safe distance can also help to increase visibility for the emergency vehicle's crew, which can help them to navigate through traffic more safely and quickly. This ultimately contributes to the safety of all parties involved.

This statement is referring to laws and regulations regarding the distance that a driver must maintain from an emergency vehicle that is responding to an emergency call or alarm. Following an emergency vehicle too closely, or stopping too close to where an emergency vehicle is responding to an alarm, can impede the emergency vehicle's ability to respond quickly and safely.

It is illegal to follow an emergency vehicle at a distance of less than 500 feet because this distance is considered to be too close and can pose a safety hazard to the emergency vehicle and its crew. When an emergency vehicle is responding to an alarm, it may need to make sudden stops, turns or change speed quickly and if the vehicle behind is too close, it may not be able to react in time and cause an accident.

It is also illegal to stop within 300 feet of where an emergency vehicle is responding to an alarm. Stopping too close to the emergency vehicle can block the view of other drivers and make it difficult for the emergency vehicle to maneuver. Additionally, it can impede the flow of traffic and make it difficult for other vehicles to pass, which can cause a backup and delay the emergency vehicle's response time.

In summary, these regulations are put in place to ensure the safety of emergency vehicle's crews and other people on the road, and to make sure that emergency vehicles can respond to an alarm quickly and safely.

The answer to the question is Option A i.e. the forces form an action-reaction pair, and the child velocity is five times the velocity of the adult and in the opposite direction.

According to Newton’s third law of motion (every force has an equal and opposite reaction force), when two bodies interact, both of them apply forces on one another that are equal in magnitude but opposite in direction. This third law of motion by Newton is also known as the law of action and reaction and the forces form a action-reaction force.

Thus, when the adult pushes the child with a force of any magnitude, the child pushes the adult with the same magnitude force but in opposite direction thus the forces are a form of action-reaction pair.

as, F = ma and the forces are equal in magnitude for both, the velocity of the adult and that of the child have an inverse relation as that of masses of both, thus the velocity of child is five times that of the adult.
