According to the gravitational force law, force existing between two objects is proportional to the mass of the two objects and inversely proportional to the square of the distance between them. When masses are doubled each. Then the force increases 16 times.
Answer:
P + C = W if in equilibrium?
P + C - W = 0; P + C = W
Explanation:
Action and reaction are equal and opposite according to newton's third law of motion. a force is that which tends to change a body's state of rest or uniform motion in a straight line, recall
P is the upward force the person exerts on the crate,
C is the vertical contact force exerted on the crate by the floor,
W is the weight of the crate
let the sum of upward forces be on the left hand side of the equation and the sum of downward forces on the right hand side.
P+C=W
P+C-W=0 if they are in equilibrium
the forces are related by the above.
Power is the scientific term defined as the rate at which
work is accomplished. Power can be seen everywhere as it is applied to our
everyday living. Power is seen when one pushes a heavy cart. It could be seen
when a baseball hitter hits the ball.

Answer:
The sound travels differently in different medium according the density of the medium.
Explanation:
The sound travels faster in dense medium and can be heard by the vibration of the bone present in the ear. The ear plugs reduce the sound intensity in both medium water and on land (air).
In air the sound is not heard properly due to the earplugs that stops the as the vibration are not able to produce as sound is not able to reach to middle ear, but Navy researchers have discovered that sound under water is heard by the bone present behind the ear, vibrations mastoid.
Answer:
The force will be doubled.
Explanation:
Just looking at the situation,
<em>We are supposing the distance in between these charges is the same in both the cases which is r</em>, so for the first normal case,
, q1, q2 are the two charges and r is the distance between them.
Now take the other case when the the Charges are doubled,
you can see clearly from the above equation that the new force which is has been doubled.
I hope it helps,
Thank you.
