Two plane mirrors stand facing each other, 3.08 m apart, and a woman stands between them. The woman faces one of the mirrors from a distance of 1.30 m and holds her left arm out to the side of her body with the back of her left hand facing the closer mirror.(a) What is the apparent position of the closest image of her left hand, measured perpendicularly from the surface of the mirror in front of her?
m behind the nearest mirror

(b) Does it show the palm of her hand or the back of her hand?


(c) What is the position of the next closest image?
m behind the nearest mirror

(d) Does it show the palm of her hand or the back of her hand?


(e) What is the position of the third closest image?
m behind the nearest mirror

(f) Does it show the palm of her hand or the back of her hand?

A) 1.3m

B) it shows the back of her hand

C) 4.86m

D) it shows the palm of her hand

E) 7.46m

F) it shows the back of her hand.

Explanation:

Detailed explanation is shown in the illustrative diagram below.

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

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.
