Answer:
86605.08 N
Explanation:
The equation to calculate the force is:
Force = mass * acceleration
The force and the acceleration does not have the same direction in this case, so we need to decompose the force into its horizontal component, which is the force that will generate the horizontal acceleration:
Force_x = Force * cos(30)
Then, we have that:
Force_x = mass * acceleration
Force * cos(30) = 25000 * 3
Force * 0.866 = 75000
Force = 75000 / 0.866 = 86605.08 N

Explanation:
Potential energy is energy that is built up and saved. When you are moving and letting out that energy, that is kinetic energy. You would be using the least kinetic energy when you aren't moving, which is at the top of the hill because you move faster the more you go down.
1. D) Solid
2. C) They are moving at high speeds and are far from each other
3. A) Gas
4.C) diagram C (as gas has the most kinetic energy so it moves and separates the most)
A)Gas (same question as 3)
5.C) melting
6.C) solid
7.D) condensation, energy is removed
8.D) B is Liquid , it’s freezing as energy is removed
9.A) Gas would change to vapour
10.B) Vaporisation
11. A) As temp increases energy of particles increase and substance changes from solid to liquid to gas
12. particles in a solid are more compact than in liquids and gases & solids maintain a fixed volume whereas liquids and gases are able to move more freely and their volume can change
