He variable that a scientist changes when conducting an experiment is called the manipulated variable
Answer:
Potential energy = 441 N
Explanation:
Given:
Mass M = 15 kg
Height = 3 m
Find:
Potential energy
Computation:
Potential energy = mgh
Potential energy = (15)(9.8)(3)
Potential energy = 441 N
They are moving away from each other
This is what i have found i hope this helps
