If the tension in a string is 100 N and the speed of the wave in the string is
100 m/s, calculate the length of the string if its mass is 100 g
62) Ratio of the sound intensities for two sound sources with intensity levels (100 dB)
and (70 dB) is
The angular frequency of a water wave has a length (124 m) and a frequency
(1.55 Hz) is :
A 3 MHz ultrasound probe detects a 4 kHz Doppler shift at an angle of 45°. What is the blood flow rate through a 3 mm diameter vessel?
If the sound intensity is 2.5 × 10^-6 W/m² at a distance of 15 m, what is the sound intensity level at a distance of 150 m?
