PLEASE HELP 20 MINS An airplane flying east accelerates at 7.00 m/s2 east for 30.0 s reaching a velocity of 375 m/s.
A. What was its initial velocity?
B. How far does it get during this 30.0 s time period?
Free response questions always require that you show your work. Points are awarded for the work shown as well as the final answer. Be sure that answers are always in significant digits and that they have a correct unit.

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

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.
