Answer:
Explanation:
Let's start by calculating the angular velocity of the Moon. We know that the period is:
So now we can calculate its angular velocity:
The centripetal acceleration is given by
where
is the radius of the orbit
Substituting,
Explanation:
The period of a simple pendulum is:
T = 2π √(L/g)
where L is the length of the pendulum and g is the acceleration due to gravity.
The period of a pendulum can be decreased by decreasing the length of the pendulum or by moving the pendulum to a place with a higher gravity.
The period of a pendulum can be increased by increasing the length of the pendulum or by moving the pendulum to a place with a lower gravity.
The average acceleration is the change in velocity divided by change in time.
Explanation:
The given data is as follows.
Electric potential energy () = ?
Formula to calculate electric potential energy is as follows.
=
=
Thus, we can conclude that the electric potential energy of the pair of charges when the second charge is at point b is .
Answer:
$531
Explanation:
If the first three months are free, take off 3 from 12. That leaves you with 9. Since you pay $59 every month, 59 x 9 is 531
