The force of gravity on the moon is said to be one-sixth of that on the earth. what
would a mass of 15000g weigh
a on the earth, and
b. on the moon?

Which fators influence ocean currents

When does your body conduct current more readily?

The sun’s mass is 2.0×10^ 30 kg, its radius is 7.0×10 5 km, and it has a rotational period of approximately 28 days. if the sun should collapse into a white dwarf of radius 3.5×10 3 km, what would its period be if no mass were ejected and a sphere of uniform density can model the sun both before and after?
