If an elevator is moving at a speed of 5 m/s and the person in it is 82 kg what is the person’s kinetic energy?

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.

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.

true is the correct answer

hope i

i don't understand. explain it clearly
