Directly proportional to pressure
Answer:
a) kinetic energy and gravitational potential energy
Explanation:
The water at the top of the fall possesses kinetic energy because the water is in motion, moving.
The water at the top also possess gravitational potential energy because it is falling under the influence of gravity. It is in a gravitational field.
Explanation:
Below is an attachment containing the solution.
Answer:
30m/s²
Explanation:
The acceleration of the motorcycle in section CD is the slope of the velocity - time graph.
Given that;
Initial velocity = 20m/s Time = 6s
Final velocity = 50m/s Time = 7s
The time interval = 7s - 6s = 1s
So;
Acceleration = 
= 
= 30m/s²
