A vector A has a magnitude of 140m and points in a direction of 48 degrees below the positive x-Axis. A second Vector B has a magnitude of 50m and points in the positive x direction. A) Draw a sketch showing how to add vectors A and B graphically. label your answer as Vector R.

B) what are the x and y components of these two vectors?
( you should be reporting 4 numbers here: 2 for A and 2 for B

C) find the x and y components of the resultant R.

D) what are the magnitude and direction of R?

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.

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
