Answer:It is easy to imagine representing a narrow beam of light by a collection of parallel arrows—a bundle of rays. As the beam of light moves from one medium to another, reflects off surfaces, disperses, or comes to a focus, the bundle of rays traces the beam's progress in a simple geometrical manner.

Which equation would you use to solve the following problem?
aivan3 [116]

The correct answer to the question is : C)The problem is asking to solve for work; W = F × d

EXPLANATION:

As per the question, the distance covered by the object d = 29 m.

The force that acts on the object is F = 289 N.

We are asked to choose the correct equation for work done.

Work is said to be done on a body or by a body if the applied force has a component along the direction of displacement.

Mathematically work done W = force × displacement

                                                  = F × d

As per the question, we are given distance covered and applied force.

Hence, the correct equation for calculating work done by the object is equation C.
