A 30.0 g sample of aluminum is heated to 100°C before being placed in 225.0mL of water. The metal-water combination reaches a final temperature of 13°C. The specific heat capacity of aluminum is 9.2 x 10^2 J/kg°C. What was the initial temperature of the water? Please answer quick!!

i. like it i'm gonna edit it tomorrow

would be false hope this out

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.
