The temperature of air changes from 0 to 10°c while its velocity changes from zero to a final velocity, and its elevation changes from zero to a final elevation. at which values of final air velocity and final elevation will the internal, kinetic, and potential energy changes be equal?

a

explanation:

because they are cartillidge

i think the answer would be b

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.

overcharge is the right answer system
