The current I, in amperes, flowing through an AC (alternating current) circuit at time t is I(t)=200sin(45πt−π3), where t≥0. Find the period and the horizontal shift.

Steam enters an adiabatic diffuser at 150 kpa and 1208c with a velocity of 550 m/s. determine the minimum velocity that the steam can have at the outlet when the outlet pressure is 300 kpa.

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e
