Your answer will be B To test a hypothesis every time you do a experiment you are testing your hypothesis like how many kernels pop in popcorn you have plain, butter, and extra butter and you think the extra butter will pop more, Also its not D because you have a question that's when you have an experiment its not C because you first have to do the experiment then you have to have a person repeat that experiment then you communicate results when it came down to A, or B I choose B because A you need to have years of research before you can prove a Scientific Law. Your answer is B.

Which statement explains how it is possible to carry books to school without changing the kinetic or potential energy of the boo

Mamont248 [21]

Answer:

a. by moving the book without acceleration and keeping the height of the book constant

Explanation:

FOR CONSTANT KINETIC ENERGY:

The kinetic energy of a body depends upon its speed according to its formula:

ΔK.E = (1/2)mΔv²

So, for Δv = 0 m/s

ΔK.E = 0 J

So, for keeping kinetic energy constant, the books must be moved at constant speed without acceleration.

FOR CONSTANT POTENTIAL ENERGY:

The potential energy of a body depends upon its height according to its formula:

ΔP.E = mgΔh

So, for Δh = 0 m/s

ΔP.E = 0 J

So, for keeping potential energy constant, the books must be moved at constant height.

So, the correct option is:

<u>a. by moving the book without acceleration and keeping the height of the book constant</u>
