marvin the martian has run out of gas and is in a circular motion around the sun. His UFO is m=500kg and he is orbiting with a radius of 3 x 10^8 m.
Given that the mass of the sun is 2 x 10^30 kg, what is the gravitational force exerted on Marvin and his UFO?
What is the tangential speed of the UFO?
How long does it take Marvin to complete one revoution around the sun?
What is Marvins angualr velocity around the sun?
predict how to changing the variables may effect the distance traveled or the speed of the race car.
The sun produces its power from the conversion of mass into energy by Einstein's equation E=mc2 where c=3x10^8 mls. the sun's intensity on the earth is 1346W/m^2, find the rate at which mass is being converted to energy in the sun
