Answer:
C) rift valley
Explanation:
A rift valley is a lowland region formed by the interaction of Earth's tectonic plates. This small rift valley has a typical formation—long, narrow, and deep. It was formed by the Thingvellir rift, where the North American and Eurasian tectonic plates are tearing, or rifting, apart over a hotspot on the island of Iceland.
The new speed of car is 10.9 m/s

According to the principle of momentum conservation, momentum is only modified by the action of forces as they are outlined by Newton's equations of motion; momentum is never created nor destroyed inside a problem domain.
Mass of the railroad car, m₁ = 7950 kg
Mass of the load, m₂ = 2950 kg
It can be assumed as the speed of the car, u₁ = 15 m/s
Initially, it is at rest, u₂ = 0
Let v is the speed of the car. It can be calculated using the conservation of momentum as :
Therefore, the new speed of care is 10.9 m/s

Answer:
A.C. Generator
Explanation:
The device designed to convert chemical energy into kinetic energy is an A.C generator.
The generator uses fuel to cause the mechanical motion of the pistons in the device.
- Chemical energy is a form of energy found between the bonds of compounds and molecules.
- When the bonds are broken, energy is released.
- The heat energy produced drives pistons and cause mechanical motion of the body.
- This is a form of kinetic energy which causes the motion of a body.
