Calculate the escape velocity from the surface of Mars.
What would be the Schwarzchild Radius for an object with the same mass

If the sun were suddenly and instantly turned into a black hole, what would
happen to the Earth?
What is the average velocity of an oxygen molecule in Earth's atmosphere,
on a nice spring day in Nashville?
Assume the sun is surrounded by a cloud of molecular hydrogen gas and that

for the Earth to capture it into an atmosphere?
