The far right.
Fg is gravity which always acts down and since we assume the floor is flat the normal, Fn, acts opposite gravity, so straight up.
But you’re probably wondering about the pushing force, Fp, and the friction force, Ff. For the Fp, consider where the applied force is coming from. The head of the broom is on the floor and the man’s arms, where he’s applying the force from, is above and to the left, so when the man pushes the broom the force is down and to the right. The broom my not be moving down, but the applied force is still in that direction. And Ff always acts against motion so since the broom moves to the right, the friction is to the left.
The North American one is im pretty sure divergent boundary but no so 100% on it
The answer is 10 m/s west.
Answer:
New length = 10.2 m
Explanation:
Let ΔL = change in length
ΔT = change in the temperature
L(0) = intial length
α = coeffient of linear expansion
Then
ΔL = αL(0)ΔT
=(2.4×10^-5)(10)(100-20)
=0.0192 m
New length = L(0) + ΔL
= 10 + 0.0192
= 10.2 m
