Answer:
<em>Well, Your answer will be is </em><em>Work. </em><em>Because, When a spring is compressed, the energy changes from kinetic to potential. This change is caused by work. </em>
<em>Good Luck!~</em>

The movement of electric charge
Answer:
the velocity of the swimmer at the bottom of the slide is 6.26 m/s
Explanation:
The computation of the velocity of the swimmer at the bottom of the slide is given below:
v = √2gh
= √2 × 9.8 × 2
= 6.26 m/s
Hence, the velocity of the swimmer at the bottom of the slide is 6.26 m/s
What counteracts gravity is buoyancy.
