Answer:
So wavelength in decimal can be written as 0.00000155 m
Step-by-step explanation:
We have given wavelength of light used in optic fibers is ![1.55\times 10^{-6}m](https://tex.z-dn.net/?f=1.55%5Ctimes%2010%5E%7B-6%7Dm)
We have to convert this wavelength in decimal form
We know that
can be written as ![10^{-6}=\frac{1}{1000000}=0.000001](https://tex.z-dn.net/?f=10%5E%7B-6%7D%3D%5Cfrac%7B1%7D%7B1000000%7D%3D0.000001)
So ![1.55\times 10^{-6}=1.55\times 0.000001=0.00000155m](https://tex.z-dn.net/?f=1.55%5Ctimes%2010%5E%7B-6%7D%3D1.55%5Ctimes%200.000001%3D0.00000155m)
So wavelength in decimal can be written as 0.00000155 m
We find the volume of the ball in cubic inches:
V = 4/3 πr³
V = 4/3 x π x 5³
V = 523.6 cubic inches
Weight = 1/100 x 523.6
Weight = 5.24 pounds.
Put x = 1
y = 12 (1)
y = 12
so x = 1
y = 12
put x = -1
y = 12 (-1)
y = -12
so x = -1
y = -12
Your correct options are A and C.
Answer:
3 socks
Step-by-step explanation:
The number of socks in the box does not matter. There are only 2 choices of socks in the box. So, if you take out 3 random socks from the box, you're guaranteed a pair.
The answer is 194.59
(72 x 100) / 37 = 194.59
