Hi there!
We know that:
U = Potential Energy (J)
K = Kinetic Energy (J)
E = Total Energy (J)
At 10m, the total amount of energy is equivalent to:
U + K = 50 + 50 = 100 J
To find the highest point the object can travel, K = 0 J and U is at a maximum of 100 J, so:
100J = mgh
We know at 10m U = 50J, so we can solve for mass. Let g = 10 m/s².
50J = 10(10)m
m = 1/2 kg
Now, solve for height given that E = 100 J:
100J = 1/2(10)h
100J = 5h
<u>h = 20 meters</u>
Types of energy transfer involve
Conduction, Convection, Evaporation,and Condensation <span />

The molecules tend to speed up and move faster throughout the substance once thermal energy increases. This is evident whenever we heat up water as its molecules tend to move faster throughout the water as thermal energy tends to increase.
Combustion<span> will </span>occur<span> when there is not enough oxygen to allow the fuel to react completely to produce carbon dioxide and water.. Hope this helps
