The force of gravity between two students is 3.5E-8 Newtons. If the first students mass is 71.0 kg and the second students mass is
67.0 kg, how far apart must the students be from each other?

r = 9521.29

Explanation:

Given:

Gravitational Force =  (Fg)

Student Mass 1 = 71 kg (M)

Student Mass 2 = 67kg (m)

Gravitational constant =  (G)

r = 9521.29

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.
