A 30-kg child rides on a circus Ferris wheel that takes her around a vertical circular path with a radius of 20m every 22s. What is the magnitude of the resultant force on the child at the highest point on this trajectory

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.

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

a=d/t

a="triangle"v/t

explanation:

a = acceleration
