angle of incidence = i
angle of refraction = r
from snells law, sin(i)/sin(r) = n ( refractive index opf the
media)
Now, let diameter of the coin be d
from geometry we see
tan(r) = (6.4 - d)/h ( h is height of mug) = (6.4 - d)/8.4
tan(i) = 6.4/8.4
sin(i) = 0.606
sin(i)/sin(r) = n = 1.33
sin(r) = 0.4556
r = 27.106 deg
tan)r) = 0.511 = (6.4 - d)/8.4
d = 2.1 cm

A 100kg person is sitting on the left edge of his boat in still water at 7.5m from the shore. The boat also has a 100kg mass, is 6. long, and symmetrical shape so that its center of mass is the middle where the whole weight of the boat can be assumed to be acting. a. How far to the right is the center of mass (CM) of the boat from the shore. b. How far is the CM of...

Why the picture 18.5.3 is not elementary Jordan region and why
we need to break it up to 2 pieces and use green theorem ? It just
looks like a Jordan region which can be applied green theorem with
out breaking up
961 18.5 GREEN'S THEOREM Figure 18.5.3 showsa Jordan region that is not elementary but can be broken up into two elementary regions. (See Figure 18.5.4.) Green's theorem applied to the elementary parts tells us that Pdx +Qdy àx...

3. Surface tension of a water strider For an animal the size of a human, surface tension seems to be a rather small and insignificant force (though it plays an important if unnoticed role in our breathing). But as animals get smaller, surface tension gets increasingly significant. (The weight of the animal goes down with the cube of the size while the surface tension only decreases linearly.) For animals like the basilisk lizard and the jacana (bird), they appear to...

2 A paint sprayer pumps air through a constriction in a 0.025- m diameter pipe, as shown in the figure. The flow causes the pressure in the constricted area to drop and paint rises up the feed tube and enters the air stream. The speed of the air stream in the 0.025-m diameter sections is 5.00 m/s. The density of the air is 1.29 kg/m3, and the density of the paint is 1200 kg/m3. We can treat the...

Chromatography: Separating Mixtures Introduction: Magic marker inks are often mixtures of several compounds. Paper chromatography is a common method of separating various components of a mixture. After separation, you can observe the different colors that make up a particular color of magic marker ink. You can also calculate a ratio Rf, which compares how far each compound traveled to how far each solvent (substance that dissolves another substance) traveled during the experiment. Rf = Ds/Df Ds = Distance traveled by...
