Find the equivalent impedance Zeq seen by the source when Vs = 5 cos (5t) v, C = 2 F, R = 3 Ω and L = 0.5 H. (Give angles in degrees and round final answers to two decimal places.) Calculate the voltage across the capacitor.

A 600 MW coal-fired power plant has an overall thermal efficiency of 38%. It is burning coal that has a heating value of 12,000 Btu/lb, an ash content of 5%, a sulfur content of 3.0%, and a CO2 emission factor of 220lb/million Btu.

An old refrigerator consumes 187 W of power. Assuming that the refrigerator operates for 17 hours everyday, what is the annual operating cost of the refrigerator, if the cost of electricity is $0.06 per kWh?

Write a single 16-bit LC-3 instruction (in binary) that clears all the bits of R6 except the least significant two bits. In other words, after your instruction executes, bits 0 and 1 of R6 will be unchanged, and the rest of R6 will be zero.

Two large, nonconducting plates are suspended 8.25 cm apart. Plate 1 has an area charge density of + 86.8 μC/m2, and plate 2 has an area charge density of + 23.6 μC/m2. Treat each plate as an infinite sheet.
