the electric force decreases because the distance has an indirect relationship to the force
Explanation:
The electric force between two objects is given by

where
k is the Coulomb's constant
q1 and q2 are the charges of the two objects
r is the distance between the two objects
As we can see from the formula, the magnitude of the force is inversely proportional to the square of the distance: so, when the distance between the object increases, the magnitude of the force decreases.
They believe the distortions happened when two galaxies collided.
Hope This Helps :)
We know,
V= f× wavelength
10.5= f×0.15
f=10.5/0.15
f= 70 Hz
Answer:

Explanation:
Velocity can be found using the following formula:

where p is the momentum and m is the mass.
The woman has a mass of 55 kilograms and a momentum of 200 kilogram meters per second.

Substitute the values into the formula.

Divide. Note that the kilograms, or kg, will cancel each other out.


The woman's velocity is 3.63636364 meters per second.
