Heat flow includes conduction, convection, and radiation. Conduction involves heat transfer through atoms bumping into each other.
The answer is B-plus.
The object is accelerating to the right, and up.
Answer:
The resulting static friction force acting on the crate is 10 N.
Explanation:
Given that,
Coefficient of static friction = 0.50
Normal force = 20 N
We need to calculate the resulting static friction force acting on the crate
Using formula of static friction force

Where, N = normal force
= Coefficient of static friction
Put the value into the formula


Hence, The resulting static friction force acting on the crate is 10 N.
