Probably because summer has a less chance to have cloudy and cold days rather than having hot days and how the sunsets and rises. And Global Warming has an effect on summer more (And making winters hotter too but still).
Answer:
normal force = 10 N
Explanation:
Given data
frictional force = 0.400 N
coefficient of kinetic friction = 0.04
Solution
we get here normal force that is express as
normal force = ............1
put here value and we will get value
normal force =
solve it we get
normal force = 10 N
