distance traveled by motorcyclist in time t is 

Distance traveled by Police in time t is 

put 

Police officer's speed at that time is 

Distance traveled by each vehicle is 

 
        
             
        
        
        
In addition to possibly releasing harmful chemicals in the environment, mining is considered B. The most dangerous job in the United States.
        
             
        
        
        
Answer:
Law 1. A body continues in its state of rest, or in uniform motion in a straight line, unless acted upon by a force.
Law 2. A body acted upon by a force moves in such a manner that the time rate of change of momentum equals the force.
Law 3. If two bodies exert forces on each other, these forces are equal in magnitude and opposite in direction.
 
        
             
        
        
        
Answer:
7.401 * 10^(-15) N
Explanation:
30 electrons will have a charge:
30 * -1.6022 * 10^(-19) C
= - 4.806 * 10^(-18) C
The relationship between electric field and electric force is:
E = F/q
This means that force, F, is 
|F| = |E|*|q|
|F| = |1540| * |-4.806 * 10^(-18)|
|F| = |-7401.24 * 10^(-18)|
|F| = 7.401 * 10^(-15) N
