Two equal forces act in opposite direction on objective A. Two unequal forces act in opposite directions on object B. If these are the only forces acting on objects A and B, which of the following conclusions is true? A. Only objects A will accelerate. B. Only object B will accelerate. C. Both objects A and object B will accelerate. D. Neither objects A nor object B will accelerate.

d

Explanation:

Equal forces acting in opposite directions are called balanced forces. Balanced forces actingon an object will not change the object's motion. When you add equal forces inopposite direction, the net force is zero.

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.
