7°

b.
40°

c.
43°

d.
47°

e.

answer 8 , noon Sun angle = 25.5° , so correct option is B. 25.5°

answer 9 , noon solar Sun angle = 43° , so here correct option is C. 43°

Explanation:

question 1st

given data

New York City 41° N

to find out

lowest noon Sun angle during the course of the year

solution

we know that in the December

the Sun is directly over head at  23.5° S latitude

so

noon sun angle will be

noon Sun angle = 90 - ( 41 + 23.5 )

noon Sun angle = 25.5°

so correct option is B. 25.5°

and

next question

given data

solar declination = 7° S

to find out

what is the noon solar Sun angle in Denver , Colorado (40° N)

solution

we have given that 7° S

it mean that sun is at directly over head at 7° S  latitude

so

noon solar Sun angle = 90 - ( 40 + 7 )

noon solar Sun angle = 43°

so here correct option is C. 43°
