The diameter of the column of the water as it hits the bucket is 4.04 cm
The equation of continuity occurs in the fluid system and it asserts that the inflow and the outflow of the volume rate at the inlet and at the outlet of the system are equal.
By using the kinematics equation to determine the speed of the water in the bucket and applying the equation of continuity to estimate the diameter of the column, we have the following;
Using the kinematics equation:




From the equation of continuity:







Since diameter = 2r;
∴
The diameter of the column of the water is:
= 2(2.02) cm
= 4.04 cm

Answer:
58515.9 m/s
Explanation:
We are given that



We have to find the speed (vf).
Work done by surrounding particles=W=0 Therefore, initial energy is equal to final energy.





Using the formula


Where mass of sun=
