a 50 gram copper mass is heated by placing it at 100 degrees Celsius it is then placed in a 35 g copper colorimeter containing 120 gram of water at 20 degrees Celsius the final temperature of the mass and water is 23 degrees Celsius what is the specific heat capacity of copper text specific heat capacity of water is 4200​

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.
