Your boss asks you to adjust the temperature so that a sound wave travels more quickly through the air. You increase the temperature from 30 degrees to 36 degrees. Velocity of sound in air = 331.5 m/s + 0.59 m/s*°C times (the new temperature) v = 331.5 + 0.59 * 36 v= 352.6 Hz.

If a tank filled with water contains a block and the height of the water above point A within the block is 0.6 meter, the pressure at point is 5.88kPa

p= 1000 kg/m3*9.8 m/s2*0.6m = 5.88kPa.

You adjust the temperature so that a sound wave travels more quickly through the air. You increase the temperature from 30 C to 36 C. The velocity of the sound wave at this new temperature is 352.6 m/s. Solution: v = 331 + 0.6T, where v is the velocity of the sound wave in units of m/s and T is the temperature measured in degrees Celsius. When the temperature is 36°C, the velocity of the sound wave is: v = 331 + (0.6)(36) = 331 + 21.6 = 352.6 m/s.
