The right answer for the question that is being asked and shown above is that: "d. electrical to electromagnetic." the type of energy transfer is made possible by a nine-volt battery in a calculator is that of d. electrical to electromagnetic<span>

First I’ll show you this standard derivation using conservation of energy:
Pi=Kf,
mgh = 1/2 m v^2,
V = sqrt(2gh)
P is initial potential energy, K is final kinetic, m is mass of object, h is height from stopping point, v is final velocity.
In this case the height difference for the hill is 2-0.5=1.5 m. Thus the ball is moving at sqrt(2(10)(1.5))=
5.477 m/s.
