A pump was used to compress the gas in a tube. As the volume of the gas decreases, the pressure of the gas increases.
(a) One of the student's results is given below.
pressure = 1.6 x 10^5 Pa
volume = 9.0 cm3
Calculate the volume of the gas when the pressure was 1.8 * 10^5 Pa.
The temperature of the gas was constant.
Volume =

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.

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
