The final mass after decay can be obtained by using under given relation:
half life period of As-81 = 33 seconds
mf = mi x (1/2^n)
= 100 x ( 1/2^(43.2/33))
= 40.4 %
When you breathe on a cold window and it fogs up, that change of state is called: Condensation.
Condensation is: The process in which molecules of a gas slow down, come together, and form a liquid water that collects as droplets on a cold surface when humid air is in contact with it.
I know this because I learned it in science class in school.
Hope I helped!

Inertia is the name. Inertia is when a moving object stays in motion unless stopped by an outside force. This is Newton’s first law of motion
Answer:
Mantle layer
Explanation:
The convection of the mantle layer is when energy in the form of heat is transferred from the interior of the earth to the top of the planet, creating convection currents.
This convection in the mantle causes movements in the earth's tectonic plates, which are found in the lithosphere, so the <u>movement of Eath's lithosphere is caused by convection within the mantle layer on the earth</u>. This plate movements can cause earthquakes or volcanic eruptions.
