Answer:

A. Trapping energy from the sun in the earth's atmosphere

Explanation:

The gases in the atmosphere have detrimental role in the global climate. The greenhouse gases, such as the carbon dioxide and methane have the ability to trap heat into the atmosphere. the heat that is trapped is the one that is bounced back from the earth's surface and back into the space, but these gases manage to retain big portion of it. As more and more heat is trapped, the atmosphere gradually becomes warmer, resulting in global climate changes, and overall a warmer earth, thus having the effect of the greenhouse on the planet.

Iodine-131, a beta emitter, is one such product of nuclear fission, extremely dangerous because it is typically produced in huge
zhuklara [117]

Answer:

0.00568

Explanation:

Recall that the fraction of radioactive material left after a time (t) is obtained from the formula;

N/No = (1/2)^t/t1/2

Where;

N= mass of radioactive material left after a time t

No= mass of radioactive material initially present

t= time taken for N mass of radioactive substance to remain = 60.0 days

t1/2= half-life of the radioactive substance= 8.04 days

Note that the required fraction is N/No, hence;

N/No= (1/2)^60.0/8.04

N/No= (1/2)^7.46

N/No = 0.00568
