A sample of an unknown liquid has a volume of 30.0 mL and a mass of 6 g. What is its density?

Abearing is designed to a reduce friction b. support a load c.guide moving parts such as wheels, shafts and pivots d. all of the above

The man of mass m1 and the woman of mass m2 are standing on opposite ends of the platform of mass m0 which moves with negligible friction and is initially at rest with s = 0. the man and woman begin to approach each other. derive an expression for the displacement s of the platform when the two meet in terms of the displacement x1 of the man relative to the platform.

Holes drilled several kilometers into earth’s crust provide direct evidence about earth’s interior in the form of
