In order to form a black hole, a star must be about how much more massive than our Sun?
a.
Fifty times as massive
b.
Ten times as massive
c.
Twice as massive
d.
Twenty times as massive
e.
It actually must be less massive than our Sun
Speed = distance / time.
The letter "c" is used to represent the speed of light.
c = d / t
Assuming that the difference in the light travel time between the two dates was 7.6 minutes and that 1.00 AU = 150,000,000 km determine the speed of light.
a. 299,000,000 km/s
b. 299,000,000 m/s
c. 299,000 AU/minute
d. 299 AU/s
18. According to the General Theory of Relativity, what will happen to the
light of a star located behind the sun when it travels towards an observer
on earth?rocks? *
O A. The light from the star will be reflected away from earth.
O B. The sun will block the light beam and will not reach earth.
O C. The light of the star will add up to the brightness of the sun.
O D. The gravity of the sun will slight|ly bend the passing light from the star.
