Answer:
<h2>98 J</h2>
Explanation:
The potential energy of a body can be found by using the formula
PE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 9.8 m/s²
From the question we have
PE = 5 × 9.8 × 2
We have the final answer as
<h3>98 J</h3>

Answer:
D
Explanation:
you can catch it, rolling against a surface can slow it and when you throw it in the air, gravity will slow it down until it drops
Answer:
As the temperature rises the solubility of all gases in water also will decrease.
Explanation:
The solubility of gases in water increase with the decrease of the temperature, and vice-versa.
The scape of the gas molecules from solution occurs by the breaks of the intermolecular bonds as a consequence of the increase of the kinetic energy which causes an increase in the motion of the gas molecules in solution.
That is why as the temperature rises the solubility of all gases in water also will decrease.
