<u>Answer:</u>
A plant needing full sun can be placed from a fence 4.63 ft high at a distance of 10.75 meter if the lowest angle of elevation of the sun in winter is 23° 18'.
<u>Explanation:</u>
The given figure shows the arrangement of sun, 4.63 ft high and plant needing full sun.
By using trigonometric result, tan θ = Opposite side/Adjacent side.
Substituting
tan(23° 18') = 4.63 ft/x
x = 4.63 ft/ tan(23° 18') = 10.75 m
So that a plant needing full sun can be placed from a fence 4.63 ft high at a distance of 10.75 meter.
When we subtract 15.54 from 508.9538 using the rules for significant figures, the answer would be <span>493.41.
</span>The rule for adding and subtracting numbers is that the lowest decimal places should be followed for the answer to be in a significant figure.<span>

In the textbook the kind of idealized object that described in section on radiation laws that it absorbs all the radiation falling for it because it is not giving off any radiation on its own. And about the black sweater worn by one of your classmates it goes the same.
Answer:
<u> a = V final 2___v initial2</u>
28
Explanation:
By definition for contant acceleration <u>a = V final ___v initial</u>
t
Furthermore the average speed is <u>V abg = v initial +v final</u>
2
Combine these relationships to eliminate t. 8 = Vabg t.
