A particular load has a pf of 0.8 lagging. The power delivered to the load is 40 kW from a 220-V rms 60-Hz line. What value of capacitance placed in parallel with the load will raise the pf to 0.9 lagging?
There are to be 15 states, and the device for utilization is a 22v10 chip using 8 flip flops internal to the device. The outputs are 8 LEDs and a secondary output Z that is a 1 if states 10,11,12,13 are active.
A 5.88-g bullet is moving horizontally with a velocity of +340 m/s, where the sign + indicates that it is moving to the right (see part a of the drawing). The bullet is approaching two blocks resting on a horizontal frictionless surface.
