Jaques ran a cross-country meet after school. After 3.5 minutes, he was 630 m from the starting line. After 7.0 minutes, he was 1260 m from the starting line. What was Jaques' velocity during that segment of the race?

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.

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
