One of the 64.3-cm-long strings of an ordinary guitar is tuned to produce the note latex: b_3b 3 (frequency 245 hz) when vibrating in its fundamental mode. the speed of sound in the surrounding air is 345 m/s. find the speed of transverse waves on this string. give an answer in m/s. pay attention to the number of significant figures.

Why there is no inductive reactance in dc circuits

Acar travels 40m in 8 seconds find the car speed

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.
