To get a uniform field in the central region between the coils, current flows in the same direction in each.
Answer:
Given,
mass of man = 100 N = 10 kg
height = h = 25m
since the man does not move anything with his force, work done by him is zero
work done on the man = gain in potential energy
P.E=mgh
P.E=10×9.8×25
P.E=2.45KJ
Explanation:
so, potential energy gained by man is 2.45 KJ
It is a very reactive metal with 11 protons ,12 neutrons, 11 electrons, and 1 valence electron
As AL2006 correctly pointed out the formula is 1/2 kx^2. I was thinking of force and work is the integral of force over the distance applied. So now
and
green pigment in the chloroplast is chlorophyll
