Volume is the amount of space an object or substance takes up, so if they are the same size then they will have the same volume. If you wish to test this, get a beaker, fill it up to one of the lines and make sure tou remeber which line, then place one ball in gently and see how muchbit went up, then take that ball out and do the same with the other. The results should be the same.
Hope this helps!
That's a perfect example of a chemical change,
because a new substance is formed.
I think it would be the one talking about if there’s water there would still be energy because water is used as a source of energy because there’s so much of it and it can be used again and again
Answer:
There is less gravitational force in space.
Explanation:
Gravity doesn't exist as it does on Earth. Earth's gravity is as 6 times stronger as it is on the moon.
We can find the momentum of the rock by using De Broglie's relationship:
where
p is the momentum
h is the Planck constant
is the De Broglie's wavelength
By using
, we find
The momentum of the rock is
where
is the mass and v is its velocity. Rearranging the equation, we find the speed of the rock:
