A series circuit is a closed circuit in whicj the current flows through one path.
Buckingham π theorem states that an equation involving a certain number 'n' of variables which are expressible in terms of 'k' independent fundamental physical quantities can be expressed in terms of dimensionless parameters.<span>
p = n - k
Keeping the statement of </span><span>Buckingham Pi Theorem,
We can proceed as follows:

Answer:
therefore normal reaction on the driver from the seat when the car passes through the bottom of the valley= 1520.55 N
Explanation:
let speed be v
at top of hill
mg-N = mv^2/R ( N=0 at the top of the hill)
==> mg=mv^2/R
at bottom
N-mg=mv^2/R
therefore,
N = 2mg = 2*77.8*9.81= 1520.55 N
therefore normal reaction on the driver from the seat when the car passes through the bottom of the valley= 1520.55 N
Well ice would be less dense, as water freezes it expands which would reduce density and you can tell just by putting ice cubes in water
