A progressive wave is represented by y = 10 sin ( 100πt - πx/34 ). Two layers of the wave separated by 153cm have a phase difference of

An object of dimensions 50 cm x 40 cm x 0.20 cm has a mass 60g. find its density in g/cm3 and kg/ m3

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

If jason ii needs 15 kw of power at 300 volts to operate, what amperage of current must flow through the cable?
