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.
Parallel line means they have the same slope
y = mx + b
where m = slope
y = -3 + 4
here the slope is negative 3
y = -3x + b
plug in (4, 8)
8 = -3(4) + b
b = 8 + 12
b = 20
The answer is y = -3x + 20
It is 1/6 or .16 I used Photomath
