when water in a metal pot is heated over a campfire. Primarily, by means of convection energy transfer is thermal energy moved from the fire to the bottom of the pot
<h3 /><h3>What is thermal energy?</h3>
It can be defined as the form of the energy in which heat is transferred from one body to another body due to their molecular movements, thermal energy is also known as heat energy.
Thermal energy can flow by different means such as conduction, convection, and radiation.
As given in the problem when water in a metal pot is heated over a campfire. The energy we receive around the campfire is mostly due to the effect of the radiation of the heat but the Primary means of energy transfer is thermal energy moved from the fire to the bottom of the pot because of the convection.
Thus, when water is heated in a metal pot over a campfire. Thermal energy is primarily transferred from the fire to the bottom of the pot through convection.

The speed of the car at the bottom of the hill is obtained as, 
According the principle of conservation of energy, the total potential energy of the car will be converted to maximum kinetic energy when the car is at the bottom of the hill.
where;
- <em>v </em><em>is the speed of the car at the bottom of the hill</em>
- <em>h </em><em>is the height of the hill</em>
- <em>g </em><em>is acceleration due to gravity</em>
Thus, the speed of the car at the bottom of the hill is obtained as,

I believe the correct answer is the third option. One advantage of using lasers in cutting patterns instead of traditional cutting machines would be that lasers save time by cutting through more layers of fabric. Although it would cost some energy and the initial cost would be high, you would still be able to save some money as time goes by since you will be able to produce more for a certain period of time as compared to using traditional cutting methods for the same period of time. Also, by using lasers, you can cut complex patterns easily and you will need less people in the production.
