A mass of 10kg is suspended from the end of a filled rock of length 2m and radius 1mm. What is the elongation of the rock beyond it's original length.

What happens to the light rays when they hit the specimen?

Acar of mass m goes around a banked curve of radius r with speed v. if the road is frictionless due to ice, the car can still negotiate the curve if the horizontal component of the normal force on the car from the road is equal in magnitude to 101) a) mv2/r b) mg/2. d) mg e) tan[v2/(eg)]

It takes a lot of energy to get the temperature of water to increase and eventually boil because water has a high heat.
