Ageothermal plant uses geothermal water (yes a liquid) extracted from beneath the earth using drilling apparatus. the geothermal water (a condensed liquid) comes up at a temperature of 200 c at a rate of 200 kg/s. it is used to drive a turbine that extracts 6000 kw of power. the water leaves the turbine at 80 c and enters a lake at 25 c. what is the actual thermal efficiency of the turbine in percent to three significant digits (do not enter a percent )

Wo audio speakers are placed on a vertical rail. speaker a is placed at head-level while speaker b is place at some variable height, \delta yδy, above speaker a. both speakers receive simultaneous input from a sine-wave generator so the speakers each produce a pure sinusoidal sound wave with a wavelength of 0.531 meters. calculate the lowest height that speaker b can be placed above speaker a to produce a minimum of sound heard by person standing \delta x = 7.86δx=7.86 meters directly in front of speaker a.

Immediately upon reaching its lowest point, a falling pendulum bob has its greatest amount of energy, which is the initial amount of potential energy. a. heat; less than b. heat; more than c. kinetic; less than d. kinetic; more than
