A. An energy source forces a current of 2A through a load for 10s. Suppose 2.3kJ of energy is given off by the load in the form of heat and light. Calculate the voltage drop the load. Assume the current is not time-varying. B. Suppose it requires -30J of energy to move a point charge q from point a to point b." the voltage drop Vab if (a) 4 = 2C and if (b) q = -6C.

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
