The system shows is at 20°C. Determine the height h of the water in the left side. (SG: specific gravity)​

Which graph best represents the relationship between the electric current and the rate at which a magnet is turning inside an electric generator?

The transfer of heat through the movement of a gas or liquid a. convection b. conduction c. radiation

An ideal otto cycle has a compression ratio of 10.5, takes in air at 90 kpa and 40°c, and is repeated 2500 times per minute. using constant specific heats at room temperature, determine the thermal efficiency of this cycle and the rate of heat input if the cycle is to produce 90 kw of power.
