It's true that mechanical waves require a medium for transmission.
Answer:
the answer is
Explanation:
constant acceleration
because when the object's velocity is changing then the object is accelerating or decelerating
as acceleration describe changing of velocity so the answer is constant acceleration
Acceleration is defined as the rate of change of velocity.
Acceleration = (Change in velocity) / time taken
Acceleration = (Final velocity - initial velocity) / time
As the object velocity changes by the same amount in each second, it means the acceleration is constant.
Hope I can help u
Don't know about the minimum part, but potential energy is calculated using the following formula:

You need to know the planet (or simply the gravity of the planet), the height of the roller coaster car, and the mass of the car.
