density of water =
velocity of flow =
radius of pipe =
Height of second floor =
Now we can use here Bernuoli's Equation to find the speed of water flow at second floor
Now in order to find the radius of pipe we can use equation of continuity
So radius of pipe at second floor is 0.034 meter
Explanation:
It is given that,
An electron is released from rest in a weak electric field of,
Vertical distance covered,
We need to find the speed of the electron. Let its speed is v. Using third equation of motion as :
.............(1)
Electric force is and force of gravity is
. As both forces are acting in downward direction. So, total force is:
Acceleration of the electron,
Put the value of a in equation (1) as :
v = 0.010 m/s
So, the speed of the electron is 0.010 m/s. Hence, this is the required solution.
