A balanced Y-Y four-wire system has phase voltages Van = 120 ∠∠0°, Vbn = 120 ∠∠–120°, and Vcn = 120 ∠∠120° V. The load impedance per phase is 19 + j13 Ω, and the line impedance per phase is 1 + j2 Ω. Calculate the line currents and neutral current. Please report your answer so the magnitude is positive and all angles are in the range of negative 180 degrees to positive 180 degrees.

Acoyote chasing a rabbit is moving 8.00 m/s due east at one moment and 8.80 m/s due south 4.25 s later. let the x axis point due east and the y axis point due north. find the direction of the coyote's average acceleration during that time.

How much energy will be transferred to your eardrum while listening to this sound for 1.0 min?

(8%) problem 12. a bowling ball of mass mb 3 kg 's rolled down the lane with a velocity ofy-2/ m s lt strikes a single remaining pin mp 0.93 kg head on. after the collision the bowling ball has a velocity (in the same direction) of v2 1.1 m/s. = ▲ 33% part (a) write an expression for the velocity of pin in the horizontal direction after the impact, im ,, 33% part (b) what is the pins speed in ms? 33% part (c) assuming the coefficient of friction s μ,-0.1. how far in meters could the pin slide before stopping if it doesn't topple?
