All solid objects above 0 Kelvin emit energy.
a. True
b. False

Answers

Answer 1

Answer:

Answer: true

Explanation: The zero Kelvin is the point where there is no energy between the atoms of the solid object, so there will no radiation emited, which means that there is no energy emited.

This has a lot of sense, if the object has temperature equal to zero, is logical to think that it can not radiate energy in the form of heat (or in any form)

Answer 2

Answer: True as known as "Absolute Kelvin" =
-273 degress Celsius not heat energy is left among atoms.

For example, if after you gather the the data from 100 heart patient and 70 percent of them are obese, you can draw a conclusion that obesity is linked with heart disease

hope this helps

you can draw conclusions from data, so it would be true

What happens to the acceleration of the rocket if the net force is cut in half?

Answers

Explanation:

Newton's second law of motion says that the net force is equal to the mass times acceleration:

F = ma

If the net force is halved, and the mass stays the same, the acceleration will be halved as well.

F/2 = m a/2
