Which direction does air flow within a cyclone? a. air rises. b. air sinks. c. air flows laterally. d. air does not move in a cyclone.

 a. Air rises.

A cyclone is a natural hazard, in which the large scale of air mass that rotates around a center which exhibit the air of low atmospheric pressure. It is characterized by the inward spiraling of the wind currents that rises upwards and rotates about the zone of low pressure.

On the basis of the above description, the direction in which the air flow within a cyclone is air rises.

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.

reserve is the answer
