An 800-g steel plate, in the shape of the isosceles triangle, is lying flat on a frictionless table and is initially at rest. Which of the following forces would cause the triangular plate to translate but not rotate? (In other words, which force or forces would cause the plate to change its position but not its orientation?)

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.
