Explanation:
Answer:
a )1.851
b ) 32.68°
Explanation:
The relation between critical angle and index of refraction is as follows
Sin C = 1 / μ
C is critical angle and μ is refractive index.
Given C = 47.3
Sin 47.3 = 1 / μ
0.735 = 1 / μ
μ = 1 / .735
= 1.36
This is with respect to ethanol .
1.36 = refractive index of material / refractive index of ethanol
refractive index of material = 1.36 x refractive index of ethanol
= 1.36 x 1.361 = 1.851
If critical angle for this substance be A
Sin A = 1 / 1.851 = .54
A = 32.68° .
Answer:
Both hemispheres receive the same amount of sunlight during <em>both autumnal equinox and vernal equinox
</em>
Explanation:
The vernal or spring equinox happens around March 20 or thereabouts yearly. Equinoxes and various seasons happen as the Earth orbits the Sun and the Earth's orbit. Thus, we have Autumn equinox and spring or vernal equinox. During the Northern hemisphere spring and summer, the northern hemisphere is tilted towards the sun while during the Autumn and winter the northern hemisphere is tilted away from the sun.
During the autumn and spring equinoxes, the earth is neither tilted away or towards the sun. This means that both northern and southern hemisphere receive equal sunlight during these periods: that is hours of daylight and night are roughly about the same.
Answer:
If we are upset, often our mind cannot think straight. we need to take deep breaths, and focus on reality. When we are upset we do things out of anger.
