Answer:
Convection
Explanation:
Convection refers to the transfer of heat by the actual movement of the heated molecules from the hot parts to the cooler parts.
Thus, the two diagrams show illustrate transfer of heat by the movement of molecules of a fluid.
This mode of heat transfer is known as convection. It is the concept illustrated by both diagrams.
Only when the torque is constant the work done is done during angular displacement. So the correct option is d.
Work done by the force is calculated as the dot product of force and angular displacement of the point of application of force. It is equal to the change in rotational kinetic energy of the body.
Work done by a torque can be calculated by taking an analogy from work done by force.
Work done = torque × angular displacement
So work is done by a torque during angular displacement only when torque is constant.
If a torque applied on a body rotates it through an angle ω, the work done by torque is
W = ζ × ω
