Achef places sugar crystals in a cooking pan. he turns on the burner under the pan. in a few minutes, the sugar begins to melt. which process is most directly responsible for transferring heat from the burner into the sugar? radiation convection conduction resonance

Thermal conduction

Explanation:

Heat can be transferred from one body to another by three processes i.e.

1. Radiation

2. Conduction

3. Convection

In this case, a chef places sugar crystals in a cooking pan. He turns on the burner under the pan. In a few minutes, the sugar begins to melt. The process responsible for transferring heat from the burner into the sugar is thermal conduction.

It is a process of transferring heat when two bodies are in contact with each other. The heat conduction depends on four factors i.e. area of cross section, temperature gradient, path length and properties of materials.

Here, heat is moving to the pan and then it is absorbed from the pan to the sugar. Hence, the correct option is (c) " conduction ".        

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
