It takes 93.4 J of energy to heat a certain mass of a sample of lead from 22.3°C to 40.4°C. Find the mass of the lead. (Use-Specific heat of lead
=0.129 J/g-K)​

layer a is the exosphere and layer b is the thermosphere.   is the answer i think but i hope this .

i think they are all correct

explanation:

they seem good

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

it has to be b, about 97 percent.
