Answer:
The molecules in hot air are moving faster than the molecules in cold air.
The answer is slightly left and slightly right of the curved end of the horseshoe.
50π m ≈ 157 m
Explanation:
100 rev/min (2π rad/rev) / (60 sec/min) = 3⅓π rad/s
d = ωrt = 3⅓π(0.50)(30) = 50π m ≈ 157 m
Answer:
Explanation:
Given
inclination 
coefficient of kinetic friction 
As crate is moving Down therefore friction will oppose the motion
using FBD
