The notion of potential energy is related to the work done by the forces on the physical system to move it from one position to another in space. That is to say in practical terms it can be calculated by the Force applied in a certain distance. Mathematically this is
Here,
PE = Potential Energy
W= Work
F = Force
d = Distance
Replacing we have,
Therefore the potential energy stored in the bow the moment before the arrow is released is 12J.

The fraction of the water must evaporate to remove precisely enough energy to keep the temperature constant when water at 37°c has a latent heat of vaporization of lv = 580 kcal/kg is 2.58 times 10 to the minus 3.
Vaporization is the process by which a substance is transformed from its liquid or solid state into its gaseous (vapour) state. Boiling is the term for the vaporization process when conditions permit the creation of vapour bubbles within a liquid. Sublimation is the process of directly converting a solid to a liquid.
Boiling and evaporation are the two processes that cause vaporization. Evaporation is the process by which a liquid body's surface changes from a liquid to a gas, as in the case of a drop of water on hot concrete evaporating into a gas. A liquid is said to be boiling when it is heated to the point at which it begins to give off steam, as when you boil water on a stove. The process of converting a substance from its liquid or solid state into its gaseous (vapour) state is known as vaporization.

Answer:
149,700,000 km (= 1.50 x 10⁸ km)
Explanation:
Given,
Speed of light, c = 300,000 km/s
Time Taken = 8 min 19 s = 499 seconds
Recall, Distance = Speed x Time
= 300,000 km/s x 499 s
= 149,700,000 km
= 1.50 x 10⁸ km
