Your initial hypotheses to describe projectile motion are given to you in Eq. 5 and Eq. 6. Write down the mathematical models that you would use to represent Eq. 5 and Eq. 6 (reference p. 2 of the Graphical Analysis guide).Make sure to explain what terms in the physical model the parameters in your mathematical model refer to.

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.

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
