Lets take a small element of rod on it with very small size
Its total charge on rod is dQ
so we will have potential at the center of curvature due to small point charge is given as
here given that
radius (R) = a
now the potential due to complete semicircular arc is given as
we know that
now we have
I believe it is A, if I am remembering correctly from my last semester class.
The correct answer is The organism did not exist at location 2 (C).
<span>The weight lifted by a machine to the applied force on a machine is called mechanical advantage.
This is written as Mechanical advantage, M. A, = load(weight)/effort.
So for 1) M.A = 2 and load = 2, 000lb = 8896.446N.
So 2 = 8896.446/ effort
Effort = 8896.446/2 = 4448.48
Similarly for M.A of 2, 000, 000 we have
Effort = 8896.446/ 2, 000, 000 = 0.004448</span>
Yes because if energy could have a positive change why can you not have a negative change
