You see a "no u-turn" sign at the intersection. may you make a u-turn at the intersection if the traffic signals are operating?

Wavelength,frequency,and energy are related.what happens to a wave as it’s wavelength gets shorter?

The energy produced as a result of this flow of electrons from atom to atom is called

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
