The formula for acceleration due to gravity can be
calculated using the formula:
g= G m / r^2
where g is gravity, G is gravitational constant, m is
mass, r is radius
So we can see that if we increase m by 4, so g also
increase by 4. But if the radius is decreased to ¼, therefore the gravity will be
divided by (1/4)^2. So:
4 / (1/4)^2 = 64
So the gravity on the surface will be:
64 g
<span>(64 times that of Earth’s gravity)</span>
The period of a simple pendulum depends only on the length of the pendulum and the gravitational acceleration:
where L is the pendulum length and g the gravitational acceleration.
The problem says that Maya and the swing form a simple pendulum, so we can use this formula to calculate the period of Maya's motion, using the length of the swing (L=1.8 m):

Answer:
In the case of an electric bulb, the electrical energy is converted to light and heat. The amount of electrical energy put into a bulb = the amount of light energy (desirable form) plus the heat energy that comes out of the bulb (undesirable form).
