For each pair of vehicles, choose the vehicle that would experience the greatest force of impact in a collision. Type your answer in the column on the right. Remember, Force = mass x acceleration Vehicle A is moving at 35 mph. Vehicle B is moving at 45 mph. Truck X hits a tree. Truck Y hits a wooden fence. Vehicle Y is carrying five passengers. Vehicle C is carrying only the driver. Motorcycle A runs into a haystack. Motorcycle B runs into a concrete divider.

the answer is a. at the equator

the results is a decrease in air temperature with an increase of altitude.

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.

i think the answer is a, hope this : )
