Answer:
Conduction, radiation and convection all play a role in moving heat between Earth's surface and the atmosphere. Since air is a poor conductor, most energy transfer by conduction occurs right near Earth's surface
Answer:
8.1 N-m
Explanation:
We are given that
Mass=m=4.9 kg
Length=L=3.1 m
We have to find the magnitude of torque (due to the force of gravity).
We know that
Using the formula
Hence, the magnitude of torque =8.1 N-m
