What is the weight of a text book whose mass is 2.4 kg measured on the moon? the gravitational acceleration on the moon is approximately 1/6 that on the earth.

What is the conversion factor between kg/m^3 and g/m^3. express your experimental values for the densities in kg/m^3.

The necleus of an atom is made up of what subatomic particles?

Suppose a wheel with a tire mounted on it is rotating at the constant rate of 2.15 times a second. a tack is stuck in the tire at a distance of 0.373 m from the rotation axis. noting that for every rotation the tack travels one circumference (a) find the tack's tangential speed. (b) what is the tacks radial acceleration?
