At an amusement park water slide, people slide down an essentially frictionless tube. The top of the slide is 3.0 meters above the bottom where they exit the slide. (g = 10 m/s) What kind of energy involved in this situation? Which kind of energy has changed to which?

Explanation: Sorry sister

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.
