To remove a nut from an old rusty bolt, you apply a 100-N force to the end of a wrench perpendicular to the wrench handle. The distance from
the applied force to the axis of the bolt is 25 cm. What is the torque
exerted on the bolt in N-m?

close lines strong magnet less close weaker

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.
