(1) A 100 meter length of steel changes temperature by 30 C during the course of a day. If the coeffcient of thermal expansion of steel is 12 parts per million per C, what is the change in length of the steel?
(2) A volume of gas initially at 37 C is compressed by a factor of 10 (VFinal = 1/10VInitial). If the pressureincreases from 112 kPa to 1904 kPa, what is the final temperature?
The position vector of a 1.0-kg particle is given by r = 3 i + 2 j + 5 k and its velocity by v = 8 i - 2 k. Find the magnitude of the particle's angular momentum in kg.m2/s
A motorcyclist is able to ride on the vertical wall of a bowl- shaped track . his weight is counteracted by the friction of the wall on the tires. what force increase or decrease if he rides faster.
Two wheels have the same mass and radius of 4.5 kg and 0.39 m, respectively. One has (a) the shape of a hoop and the other (b) the shape of a solid disk. The wheels start from rest and have a constant angular acceleration with respect to a rotatio..
