Three point charges are arranged at the corners of a square, with charge -Q on both the particle at the upper left corner and the particle at the lower right corner and with charge +2Q on the particle at the lower left corner.
A heat engine has a maximum possible efficiency of 0.800. If it operates between a deep lake with a constant temperature of 287.0 k and a hot reservoir, what is the temperature of the hot reservoir?
A sound wave traveling at 340 m/s is emitted by the foghorn of a tugboat. An echo is heard 2.60 s later. How far away is the reflecting object? reply in units of m.
find the coefficient of linear expansion for the material of which the rod is made.
A flywheel having constant angular acceleration requires 4.6-{rm s} to rotate through 162 rad. Its angular velocity at the end of this time is 100 rad/s. Find out the angular velocity at the beginning of the 4.6s interval; the angular acceleration..
