Answer:
diamerer of the hair (t) 3.11 X 10^{-5} m
Step-by-step explanation:
The first dark spot is at the zero location where the glass plates touch. To find the number of dark fringes after first dark fringe, divide 12 cm by 0.75 mm (.075 cm)
12/.075 = 160.0
total number of additional bright fringe is 156 because there is no further portion for extra dark fringe.
diamerer of the hair (t) can be derived as
2nt = (m + .5)*wavelength
2(1.52)(t) = (160.5)(589.3 X 10^{-9})
t = 3.11 X 10^{-5} m
Answer:
The 5th day must be 90
Step-by-step explanation:
The first 4 days averaged out to 80
You can find their total just by multiplying by 4. That won't tell you the exact values, but it will tell you their total when you add the 4 of them together.
80*4 = 320
Now you need to add another day into the mix. Call it x
320 + x
Now there are 5 days, not 4, and the new total is 82.
(320 + x) / 5 = 82 Multiply both sides by 5
5*(320 + x) / 5 = 82 *5
320 + x = 410 Subtract 320
-320 -320
x = 90
Answer:
i believe it is x=4
Step-by-step explanation:
10x+7=12x-1
7=12x−1−10x
8=2x
divide
x=4
Answer: b
Step-by-step explanation:
good luck... ur profile pick is hot
The angle that is supplementary to <COB is one that is next to it (in some relation)
and when you add the two angles together, they shall equal 180°.
Hope this will help
