We are given the data for the angle of incidence and angle of refraction.
The first part of the problem is to plot the deviation and the angle of incidence. The minimum deviation is 37 with 65 degrees as the corresponding angle of incidence. The maximum deviation is 69 with a corresponding angle of incidence of 30 degrees. It is not advisable to use small values for the angle of incidence since it would result to a higher deviation from Snell's Law.
Answer:
Collection of stars in the night sky that is popularly known.
The Great Diamond, Big dipper
Explanation:
An asterism is a collection of stars in the night sky that is popularly known. Asterisms are not recognised by the International Astronomical Union (IAU) as constellations. They are not constellations as constellations are a region of the night sky.
The Great Diamond is an asterism which consists of the four stars namely Cor Caroli in Canes Venatici, Denebola, Spica and Arcturus. Big dipper is also an asterism.
T is the time for a whole round.
centripetal acceleration = V^2/R,
20 = 40^2 / R, find R = 40^2/20 = 40*40/20 = 80 m, right?
Now, one round is L = 2*pi*R = 2*pi*80 = 160*pi
And T = L/v (distance/speed) = 160*pi/40 = 4*pi seconds, or ~ 12.57 s
Because one object can have more things in it. I learned it a t school today.
