D
nothing
D
Mass is Gravity
It would be cold though
The answer has to be "D" ..... because if the distance to the Earth
is not violated or compromised by the accretion disk, the Earth's orbit should remain stable.
It’s D.
D, since the mass is the same.
Except it will become a lot colder without the sun, all the oceans will freeze over, and the atmosphere will vanish, maybe even form liquid nitrogen lakes or seas on Earth' surface.
D. The earth's orbit depends mainly on the sun's mass, only a tiny bit on the sun's shape.
NOTHING would happen To Earth's orbit. Earth's orbit would be the same because the black hole has the SAME MASS as the Sun. The environment on Earth would change a lot, but Earth's orbit would NOT CHANGE.
D) The Earth’s orbit would remain the same

a black hole the same mass as the sun would be so small as to be almost undetectable........ however... from the same position... it would exert the same force upon the planets as the sun does now.......... so.... D
D) The Earth’s orbit would remain the same
