You must exert a force of 4.5 N on a book to slide it across a table. If you do 2.7 J of work in the process, how far have you moved the book?

0.6 metres

Explanation:

Given that,

force on a book = 4.5N

work done = 2.7 J

Distance moved by the book = ?

Recall that work is done when force is applied on an object over a distance. Hence, work = force x distance

2.7J = 4.5N x distance

distance = 2.7J / 4.5N

distance = 0.6 m

Thus, you must have moved the book 0.6 metres far.

why is cellular respiration important for homeostasis?

it changes food into energy that the organism can use.

which of the following is most likely to happen if a cell is not able to divide?

the cell will not be replaced when it is damaged.

explanation:

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
