Answer: +1.77
Explanation:
Big dipper is the asterism made of seven bright stars in Ursa Major constellation. An asterism a pattern formed by joining the bright stars in the night sky. On the other hand, whole night sky is divided into 88 areas called constellations. These asterisms are used to identify the constellations.
The brightest star of the big dipper is Alioth which is the 32nd brightest star in the night sky. Its apparent magnitude is +1.77.
on a boundary with corn oil. What is the angle of refraction, to the nearest degree, for this
light ray in the corn oil?
The angle of refraction of light ray in the corn oil is 20°.
Angle of refraction is the angle the refracted light ray makes with the normal to the oil-air interface.
Given data:
Angle of incidence = 30°
Analysis:
The refractive index of oil is 1.47.
Using the formula for refractive index(n) =
1.47 =
1.47(sin r) = sin 30
sin r =
sin r = 0.3401
r = arc sin(0.3401)
r = 19.88° which is approximately 20°

Answer:
its 20 degrese
Explanation:
Answer:
The darker the object, the better it emits heat, because it's a better absorber of light. On the other hand, a white object appears white because it reflects all the different wavelengths and absorbs little to no light. It doesn't absorb much energy, then, and puts off little to no heat.
