9.8m per seccond is the speed of gravity if you drop something like a ball from a tower
Answer:
It doesn't give light
Explanation:
No Flowing of electricity
From the first law of thermodynamics, we use the equation expressed as:
ΔH = Q + W
where Q is the heat absorbed of the system and W is the work done.
We calculate as follows:
ΔH = Q + W
ΔH = 829 J + 690 J = 1519 J
Hope this answers the question. Have a nice day.
