Answer:
Explanation:
mass of the water being lifted per second
m = volume x density
= 6.2 x 1 = 6.2 kg
height by which water being lifted
h = 75 - 21
= 54 m
increase in potential energy of water per second
mgh
6.2 x 9.8 x 54
= 3281.04 J /s
= 3281.04 W.
Explanation:
4.he invented the atomic model with all different electrons proton and neutrons
5. this was important as this was developed and is still used in the modern day
Answer:
N = 195 turns
Explanation:
The inductance of the inductor, L = 500 μH = 500 * 10⁻⁶H
The length of the tube, l = 12 cm = 0.12 m
The diameter of the tube, d = 4 cm = 0.04 m
Radius, r = 0.04/2 = 0.02 m
Area of the tube, A = πr² = 0.02²π = 0.0004π m²

The inductance of a solenoid is given by:
