Ksivusya [100]

Answer:

Basically an object in motion or at rest will remain that way unless an outside force acts against it.

Explanation:

Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia.

Light travels extremely rapidly (c = 3.00×108 m/s ). Suppose you had to travel 40 miles to work every day. If you traveled at th
Reptile [31]
Given , Speed of light = 3 × 10⁸ m/s 
             Distance = 40 × 1.61× 1000 m 
                           = 264400 m
 We know that, speed = distance/time 
                   so, time = distance/speed
                             t = 264400 / 3 × 10⁸
                             t = 0.00881333 sec  Approx
The answer is 0.00881333 sec  Approx
