The sun is made up of defferent gases due to high massive therefore th density is commonly very high o the gravity is more thwe any other planet in our solar system.
when the half-life is the amount of time which the radioactive isotopes need to
be in half.
So when w start with 32 g of unobtanium 53 so :
1- after 20 sec the number of grams remain = 32/2
= 16 g
2- and after 40 sec the number of grams remain
16 g will cut in half:
= 16 / 2
= 8 g
3- and after 60 sec the number of grams remain
8 g will cut in half:
= 8g /2
= 4 g
4- and after 80 sec the number of grams remain
4 g will cut in half:
= 4 g /2
= 2 g
5-after 100 sec the number of grams remain
2 g will cut in half :
= 2g /2
= 0 g
after 100 sec there are no grams remain
Answer: condensation and melting
Explanation: it requires the most energy
Answer:
Aquifer
Explanation:
Instead of snowcapped mountains that store water in advance of warmer temperatures, most of our drinking water comes from underground "mountains" of porous materials called aquifers which are replenished by rain. The Biscayne Aquifer is South Florida's lower east coast's primary source of fresh water.
