At 17°c, a rod is exactly 20.09 cm long on a steel ruler. both the rod and the ruler are placed in an oven at 306°c, where the rod now measures 20.18 cm on the same ruler. what is the coefficient of linear expansion for the material of which the rod is made? (in degrees c^-1)

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

The motor m applies a time-varying force of f (200 t) n, where t is in seconds. box b with mass 200 kg starts from rest, and the coefficients of kinetic and static friction are 0.2 and us 0.3 the acceleration due to gravity is g 9.8 m/s2 b 300 a) find the time ' when the box starts to move. b) calculate the speed of the crate at 3 s c) calculate the power delivered by the motor at t 3 s
