Calculate the angular velocity of planet Mercury and its tangential speed around the Sun. Mercury's distance from the sun is 5.7909227 x 10^ 10 m. Mercury's mass is 3.285 × 10^23 kg. Period = 88 days.

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

the closer the planet is to the sun, the larger the gravity
