Cho 1 số tụ điện giống nhau có cùng điện dung C=3yF. Nêu cách mắc dùng ít tụ nhất đẻ được bộ tụ có điện dung C=5uF

What are the differences and similarities of a compression wave and a transverse wave?

Acoal-fired plant generates 600 mw of electric power. the plant uses 4.8 x 10^6 kg of coal each day, and the heat of combustion of coal is 3.3x 10^7 j/kg. the steam that drives the turbines is at a temperature of 300° c, and the exhaust water is at 37° c. (a) what is the overall efficiency of the plant for generating electric power? (b) how much thermal energy is exhausted each day? (c) what is the change in entropy of the universe for this heat engine? (d) using the same heat reservoirs, what is the maximum possible (carnot) efficiency for a heat engine?

What is the rate of 12 liters of water moving through a water hose in 4.0 minutes?
