g A cylindrical tank, open at the top, of diameter 15 cm is filled with water to a height of 5 m. A pinhole is drilled into the side of the tank at a location that is 2.75 m below the surface of the water. According to Bernoulli's equation, find the velocity of the water emerging from the pinhole in m/s. Do not include units in your answer as Blackboard will not understand.

The answer is: 6.3mi got it right

The correct option is this: the sound waves from the two trombones have slightly different frequencies.from the question given above, we are told that the loudness of the sounds were increasing and decreasing, this is because the frequencies of the two sounds are different. the means that the number of waves that pass a fixed point in a given amount of time differ for both sounds.
