Answer:
A. The objects have coupled together after the collision.
Explanation:
All of the other answer choices are traits of an elastic collision.

Answer:
since small stone has less mass so the gravitational pull of the earth is lesser in case of this but this is not for the bigger stone as the gravitational pull of the earth is greater...
PLEASE MARK BRAINLIEST!!!!!
Option D is the correct answer. Option C is incorrect cuz temperature is not constant in outer space which makes difficult for classification. So composition of objects matters. Hence D. Hope it helps.
No. A substance floats or sinks in another substance because of
the densities of both of them.
If the density of the substance is more than the density of the other
one, it will sink. If less than the density of the other one, it will float.
Answer:
a)
b)
Explanation:
For this case we have the following frequency given:
We can convert this into Hz like this:
If we have a fundamental wave we need to satisfy the following condition:
If we solve for the wavelength we got:
We know that the velocity of the light is
And if we replace into the last formula we got:
Part b
For this case we can use the same formula but on this case the velocity of the sound at 20C is approximately 343 m/s, the frequency is given by:
We use the same wavelenght from the previous part
And if we replace the new values we got:
