The picture shows an example of velocity
To calculate the speed of the water leaving we use the formula,
Here h is the height of the water above the hole and g is the acceleration due to gravity.
Given,
Substituting the given value in above formula we get
Thus, water flow from a hole at the speed is 10.7 m/s
Light. Because we all should know that light travels faster than sound so light will get there first
Answer:
Angle will be
Explanation:
We have given frequency of the sound f = 600 Hz
Vertical opening is of 0.8 meter
So width D = 0.8 m
Velocity of sound v = 340 m/sec
We know that wavelength
Now for the first minimum
