Answer:
The number take for the "radius" is normally taken to be the radius from the center to the event horizon, since nothing inside that can be observed, and since it is a point of no return. This radius is directly proportional to the mass of the black hole. From the Wikipedia article on event horizon: "For the mass of the Sun this radius is approximately 3 kilometers and for the Earth it is about 9 millimeters. In practice, however, neither the Earth nor the Sun has the necessary mass and therefore the necessary gravitational force, to overcome electron and neutron degeneracy pressure." The last sentence means that it is unlikely for the Sun to become a black hole, since it has too little mass to become one.

Answer
given,
initially rotating speed = 130 rad/s
final rotating speed = 0 rad/s
constant acceleration = 3 rad/s²
a) using equation of rotating acceleration
3 t = 130
t = 43.33 s
time does the disk take to stop is equal to 43.33 s
b) again using equation of rotation
angle does the disk rotate during that time is equal to 2817 rad
The light interference pattern is a series of light and dark stripes.
The bright stripes are areas where there is CONstructive interference.
The dark stripes are areas where there is DEstructive interference.
Explanation:
The wavelength of green light is about 500 nanometers, or two thousandths of a millimeter. The typical wavelength of a microwave oven is about 12 centimeters, which is larger than a baseball.
