What is tidal friction? what effects does it have on earth? how does it explain the moon's synchronous rotation?

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .

your answer is, orbit around the nucleus

float.

archimedes' principle

denser than water sinks in water.

denser than mercury would sink in it

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
