Answer:
Step-by-step explanation:
1 Knot per second is equal to an acceleration of one nautical mile an hour per second. 1 Knot per second is approximately 0.514444444 meters per second squared (SI unit). 1 kn/s = 0.514444444 m/s2.

Answer:
B. A water wheel in a dry river
Step-by-step explanation:
Work is said to be done when a force moves a body or an object through a certain distance in the direction of the force. Thus for work to be done, force and distance are required.
i.e Work done = Force x distance
It is measured in Joules.
Also, the work done by an object could be a measured of potential energy.
So that,
Work done = potential energy = mass x gravitational force x height
Considering the collage in the question, since the water wheel is in a dry river no work is done. Water wheel is a device that functions through the flow of water body, thus causing its rotation.
