I need help with this please

Heena wants to measure the volume of a ball that is 24 cm across. how should she set up her equation?

In all trials, the magnitude of the final velocity for g1 + g2 was less than the magnitude of any initial velocity. as mass increased, what happened to the velocity? the velocity decreased. the velocity increased. the velocity of g1 + g2 could not be measured. the velocity was not affected by the mass increase.

Why don't you see your reflection in water with waves or repples
