23.4 .. (a) How much work would it take to push two protons very slowly from a separation of 2.00 * 10-10 m (a typical atomic distance) to 3.00 * 10-15 m (a typical nuclear distance)

answer: what are you talking about?

explanation:

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.

the bal will not change its velocity.
