Sahil is making a graphic novel in which the villain plans to reduce the rate at which energy is released from the sun. the villain’s device can make a hollow sphere of material have a uniform density. how should sahil’s villain use the device? a. on the radiative zone, where energy is transferred through the movement of the gas b. on the convective zone, where energy is transferred through the movement of the gas c. on the radiative zone, where energy is transferred by being repeatedly absorbed and emitted d. on the convective zone, where energy is transferred by being repeatedly absorbed and emitted

The correct answer is B) on the convective zone, where energy is transferred through the movement of the gas, on edge

Explanation:

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.
