3. Suppose the pilot wished to maintain a westward heading et with a ground speed of 250 km/h however, a wind blowing towards the south at 45 km/h is blowing the plane off course
What would be the necessary airspeed and direction so that the plane remains on course?
** This problem requires a vector diagram (sketch) **
Make sure to show your orrow heads and think
about which vectors are adding up to produce
the final vector sum known as the resultant".

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.

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.
