A75-hp (shaft output) motor that has an efficiency of 91.0 percent is worn out and is to be replaced by a high-efficiency motor that has an efficiency of 95.4 percent. the motor operates 4368 hours a year at a load factor of 0.75. taking the cost of electricity to be $0.12/kwh, determine the amount of energy and money saved as a result of installing the high-efficiency motor instead of the standard motor. also, determine the simple payback period if the pu

If you drive 12 miles north and 35 miles east, what is the direct distance between you and your starting point?

As a pendulum moves closer to the equilibrium position, how do the velocity, acceleration, and force change? the velocity decreases, the acceleration decreases, and the net force decreases. the velocity increases, the acceleration decreases, and the net force decreases. the velocity increases, the acceleration increases, and the net force decreases. the velocity decreases, the acceleration increases, and the net force increases.
