Answer:
-The battery-the power source
-Closed conducting loop
Explanation:
-To produce an electric current, the following requirements must be met:
-A battery-This is the energy source than will do work on the charge thus moving from a low energy location to high energy location.
-Closed Conducting Loop-The loop is usually made of copper wires due to their high electric conductivity.
 
        
             
        
        
        
jetliner is moving with speed 146 mi/h
now we will have


now if it moves with this speed for 1.5 s
so the displacement for above time

now the deceleration of jet is given as



now by kinematics



so total displacement is given as


so displacement will be 555.7 m
 
        
                    
             
        
        
        
Answer:
Increasing the launch height increases the downward distance, giving the horizontal component of the velocity greater time to act upon the projectile and hence increasing the range.

Answer: average speed  
   The overall rate of speed at which an object moves: calculated by dividing the total distance an object travels by the total time
instantaneous speed	>      The speed of an object at one instant in time.
velocity                    >                Speed in a given direction
