(05.03 MC)During аn ultrаsоund, sоund wаves are sent by a transducer thrоugh muscle tissue at a speed of 1,300 m/s. Some of the sound waves are reflected from a metal fragment 5.0 cm into the muscle tissue. How long did it take the transducer to detect the reflected waves from the metal fragment after they were first emitted?
