Sun's energy
<span>causes air molecules to move rapidly; temperatures are high and it feels warm</span>
Answer: 25 joules
Explanation:
Recall that kinetic energy is the energy possessed by a moving object.
So, kinetic energy = 1/2 X Mass X Velocity^2
Mass = 0.5kg
Velocity = 10m/s^2
= 1/2 x 0.5kg x 10^2
= 0.5 x 0.5 x 100
= 25 Joules
Thus, the kinetic energy of the moving ball is 25 joules
The pH scale is from 1-14 and if the water is on 7, it would make it a neutral substance (C).
The answer should be 4. All of the above.
