Answer:30.50 m
Explanation:
Given
coefficient of friction between railroad and crates 
Train initial velocity (u)
To get the shortest distance brakes applied should be order of friction force between crates and railroad floor

using 
where v=final velocity
u=initial velocity
a=acceleration or deceleration
s=distance
here v=0 , u=16.94 m/s


s=30.502 m
<span>The correct answer is C. Stars are able to form from clouds of dust and gas because of the law of universal gravitation. The law of universal gravitation applies because of the fact that stars themselves are always made of hydrogen, which is a gas at first. However, in order to become dense gravity will always be needed, in order for the hydrogen atoms to be joined together.</span>
A judgement or an observation?
Answer:
a material is the resistance offered by a wire of the material which is 1 foot long with a diameter of one MIL. The resistance of a wire is directly proportional to the specific resistance of the material.
