The work-energy theorem states that the change in kinetic energy of the particle is equal to the work done on the particle:

The work done on the particle is the integral of the force on dx:

So, this corresponds to the change in kinetic energy of the particle.
the answer is spiral galaxies
Answer:
Explanation:
compressions and rarefactions
Answer:
Increase by a factor of 4.
Explanation:
The acceleration of a car moving with speed v in a circle of radius R is given by:

Now if we double the speed
in the equation above, it becomes
. Thus:

Therefore the acceleration is increased by a factor of 4.
The acceleration on surface of moon =1.67m/s^2
Weight =mass ×acceleration
=7×1.67
=11.69N
