frutty [35]

Answer:

$27.26^{\circ}$

Step-by-step explanation:

We are given that

$n_g=1.57$

$n_w=1.33$

Angle of incidence,i=37.5 degree

We have to find the angle of refraction into the water made by ray wit the normal to the surface.

Refractive index of water, $n_a=1$

By Snell's law

$\frac{n_g}{n_a}=\frac{sin i}{sin r}$

$sin r=\frac{n_a sini}{n_g}=\frac{1\times sin37.5}{1.57}$

$sin r=0.388$

$r=sin^{-1}(0.388)=22.83^{\circ}$

Again for glass water surface

Using Snell's law

Angle of incidence,i'=22.83 degree

$\frac{n_w}{n_g}=\frac{sin i}{sin r}$

$\frac{1.33}{1.57}=\frac{sin22.83}{sin r'}$

$sin r'=\frac{1.57sin(22.83)}{1.33}=0.458$

$r'=sin^{-1}(0.458)=27.26^{\circ}$

A circle has an area between 100-150 square inches,what are some possible lengths for a diameter of this circle

Ulleksa [173]

Answer:

it would range between 11.28379... to 13.819765...

Step-by-step explanation:

the circle's area formula is pi * radius^2

so you make to equation, plugging the 100 and 150 into the circle's area

you get square root of (100/pi) which gets 11.28379... for the area of 100

you do the same with 150 to get square root of (150/pi) which gets 13.819765...

those are the diameter of the circle since the diameter is double the radius which i already multiplied afterwards. so if you need the radius divide the number ive given you

A company has been forced to reduce its number of employees. Today the company has 34% fewer employees than it did a year ago. I

jenyasd209 [6]

Since there are 34% fewer, you multiply 297 x 0.34 = 100.98
Then you add 100.98 to 297 = 397.98
They had 397 employees.
