Calculate how much heat energy is required to raise the temperature of a cube of copper of side 2cm. from 300 to 320k. given: density=8933kg/m cube , atomic weight=63.55, cp=24j/k/mole
sol) heat energy required = mcTmass=d.v=8933 . (.02)^3 = .0712 kg = 71.2 gmmo of moles = 71.2 / 63.55 = 1.12 molesc=24 j/k-mole.T=20H= (1.12) . 24 . 20 =537.6 Joules (ANS)

Heater Another form of heater can be made from an old oil tin. Iron wire is wrapped round a test tube and twisted to form a handle.
A 10.0-kg object is held up by a string that will break when the tension exceeds 1.00 x 10 2 N. At what upward acceleration will the string break?
An object starts from point A and moves with constant acceleration in a straight line. 5 seconds after the start, it crosses point B, and 7 seconds after the start it crosses poin
Stress is measured by the deforming force per unit normal area. Stresses set up in an object due to of the action of forces can be divided into three broad categories (a) Ten
