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.
Answer:
Explanation:
Given
density 
diameter 
Magnetic field 
Force on the current carrying conductor placed in a magnetic field

where L=length of conductor
=angle between magnetic field and current
If the wire is floating then weight must be balanced by weight of wire

Therefore




In one of the startling coincidences sprinkled throughout
every field of math and science, the moment of maximum
height is popularly referred to as the "high" tide.
Answer:
increasing the temperature of the object
