When describing image formation for flat, shiny surfaces, what is an
important rule to remember about light rays?

State the right hand rule of the direction of magnetic field in a conductor carrying current

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

When you push downward on a book at rest on a table, you feel an upward force. does this force depend on friction? defend your answer.
