Consider the roof of the refrigerated truck compartment described in problem 7.16, but under conditions for which the truck is parked (v = 0). all other conditions remain unchanged. for αs = ε = 0.6, determine the outer surface temperature, ts, o, and the heat load imposed on the refrigeration system. hint: assume ts, o > t[infinity] and ral > 107 .

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.
