We are given an object that is speeding up on a level ground.

Let's remember that the gravitational energy depends on the change in height, therefore, if the object is not changing its height it means that the gravitational energy remains constant.

The kinetic energy depends on the velocity. If the velocity is increasing this means that the kinetic energy is also increasing.

Now, every change in velocity requires acceleration and acceleration requires a force. The force and the distance that the object moves are equivalent to the work that is transferred to the object and therefore, the change in kinetic energy. This means that the total energy of the system increases as work is transferred to the mass.

We have that the total energy of the system increases in the form of kinetic energy and that the gravitational potential energy remains constant. Therefore, the diagrams should look like pie charts that grow but the area of the segment of the potential energy stays the same. It should look similar to the following.

Which describes why the sun is a renewable resource? The sun creates biomass. The sun is continuously releasing energy. The sun
Fynjy0 [20]

Renewable source means that it can never run out or run out in a long time. In this case the sun is expected to shine for about five billion years because of the high amount of hydrogen that is stored in its core. So the answer should be "The sun is continuously releasing energy". This answer is the best because there are many other renewable resources on earth that can cause pollution.

Which of the following is not an intensive physical property?
Alex Ar [27]

Answer;

-Mass

Explanation;

-An intensive property is a physical quantity whose value does not depend on the amount of the substance for which it is measured. For example, boiling point, density, color, melting point, Odor, temperature, etc.

-Extensive properties on the other hand, do depend on the amount of matter that is present. An extensive property is considered additive for subsystems. Examples of extensive properties include: volume, mass, size, weight. length, etc.

2. What is meant by the statement that the MA of a simple machine is 3<br>​
Blababa [14]

Explanation:

MA of a machine is its mechanical advantage.

 Mechanical advantage is the ability of a machine to multiply force so as to get a work done.

  • This is done by minimizing effort and maximizing the load or output.
  • A MA of a simple machine with a value of 3 suggests that such a machine will multiply input force by a factor of 3.
  • Therefore, such a machine will amplify the force input into the system.
