Answer #1

Each motor should have a controller which has conductors to start and stop the motor. If we talk about the number of conductors to be installed one conductor for a 2 wire motor and 2 conductors must open to a 3 wire motor.

conductor size is decided according to the current that is allowed through the motor.If its a single motor the size of conductors should not be smaller than 125% of the motor, wherein multiple motor we have to multiply the full load current rating of the highest loaded motor by 1.25.

Bob is deciding how much labour he should supply. He gets utility from consumption of beer (given by C) and from leisure time (given by L), which he spends hanging out with his friend Doug. This utility is given by the following utility function: U(C, L) = ln(C) + θ ln(L) where the value of θ was determined by your student number and ln(C) denotes the natural logarithm of consumption etc. Given this utility function, Bob’s marginal utility from consumption...
