10 points

question 9

when the solar declination is 7° s, what is the noon solar sun angle in denver, colorado (40° n)?

a.
7°

b.
40°

c.
43°

d.
47°

e.
50°

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°

a maximum–minimum thermometer. the scales are fahrenheit on the inside of the u and celsius on the outside. the current temperature is 23 degrees celsius, the maximum recorded is 25, and the minimum is 15, both read from the base of the small markers in each arm of the u tube. the bulbs are hidden by a plastic housing.

six's thermometer is a registering thermometer which can record the maximum and minimum temperatures reached over a period of time, for example 24 hours. it is used to record the extremes of temperature at a location, for instance in meteorology and horticulture. it was invented by a british scientist james six, born in canterbury, in 1780; [1] the same basic design remains in use.

it is also commonly known as a maximum–minimum, minimum–maximum, maxima–minima or minima–maxima thermometer, of which it is the earliest practical design.

the thermometer indicates the current temperature, and the highest and lowest temperatures since last reset.
