I believe your answer is TRUE!
Hope this helps!:)
Answer: 197
Explanation:
Because mechanical energy and mass it speeds up
A front is a narrow region between two air masses of different densities.
It helps because it's being transported blah blah whatever the last person said when you first asked this question
The elastic potential energy of a spring is given by
where k is the spring's constant and x is the displacement with respect to the relaxed position of the spring.
The work done by the spring is the negative of the potential energy difference between the final and initial condition of the spring:
In our problem, initially the spring is uncompressed, so
. Therefore, the work done by the spring when it is compressed until
is
And this value is actually negative, because the box is responsible for the spring's compression, so the work is done by the box.
