A force of 200 N is applied to a 40 kg object. What is the acceleration of
the object?

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.

its c i just checked it

this could be newton#'s law of cooling. the cooling curve is exponential

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
