Speed=distanse/time
144/12=12
ans is 12m/s
The gravitational force between two masses is given by:

where
G is the gravitational constant
m1 and m2 are the two masses
r is the separation between the two masses
We see that the force is proportional to the inverse of the square of the distance:

therefore, if the distance is tripled:
r'=3r
The force decreases by a factor 1/9:

Since the original force was 36 N, the new force will be
Answer:
The battery is an electric energy source, which is being used to power a motor. The motor turns this electricity into kinetic energy as it spins the fan, creates heat from friction, and creates noise as stated by the problem.
Explanation:
Answer:
Explanation:
Given
mass of car 
Initial velocity of car
towards east
Time taken to stop 
Force exerted 
change in momentum is given by impulse imparted to the car



negative Sign indicates that impulse is imparted opposite to the direction of motion
magnitude of momentum 
I think it’s B hope it helps:)
