Answer:
-2.5 m/s²
Explanation:
The acceleration of a body is the change in it's velocity with time.
The change in velocity with time can be obtained as the slope of a velocity time graph ;
Acceleration = (change in velocity / change in time)
Taking the slope :
Change in Velocity = △y = y2 - y1
Change in time = △x = x2 - x1
(10, 15) ; (0, 40)
△y / △x = y2 - y1 / x2 - x1 = (40 - 15) / (0 - 10)
△y / △x = 25 / - 10 = - 2.5 m/s²

Explanation:
Therefore, if the distance between the two charges is doubled, the attraction or repulsion becomes weaker, decreasing to one-fourth of the original value. If the charges come 10 times closer, the size of the force increases by a factor of 100. The size of the force is proportional to the value of each charge.

Formula which describes v in terms of t is 
</h2>
Explanation:
A train travels the distance between the points A and B, which is 600 km
Distance between A and B = 600 km
Speed of train = v
Time taken by train = t
We know that
Distance traveled = Speed of travel x Time taken
600 = v x t
Formula which describes v in terms of t is
Explanation:
the moment of couple that is calculated by multiplying the size of one of the force by the perpendicular distance between two forces is torque of a couple
