Answer:
<h3>50m</h3>
Step-by-step explanation:
Given the dimension
Length of the rectangle = 8cm
Width = 5cm
Note that when the scale was 1:7, syla multiplied the width by a factor of 7 i.e 5*7 = 35m
If syla changes the the scale to 1 cm : 10 m for the rectangle, then the width of the shorter side will be multiplied by a factor of 10 due to the change in scale i.e;
5 * 10 = 50m
Hence the width of the new stage will be 50 m
Answer:
distance = 9.495 mm
Step-by-step explanation:
Given data
slits distance = 0.100 mm
viewing screen distance = 1.50 m
wavelength = 633 nm
to find out
how far apart are the bright fringes on the viewing screen
solution
we use here double slit diffraction condition that is
d sin(θ) = m λ .......................1
here m = 0, 1 , 2 , 3 .....
and here for θ small so
sin(θ) = tan(θ) = ![\frac{x}{l}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7Bl%7D)
so x = l sin (θ)
so from equation 1
x =
and
x1 =
...............2
x2 =
..............3
so distance x2 - x1 will be
distance = ![\frac{\lambda l}{d}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Clambda%20l%7D%7Bd%7D)
distance = ![\frac{633*10^{-9}*1.5}{0.1*10^{-3}}](https://tex.z-dn.net/?f=%5Cfrac%7B633%2A10%5E%7B-9%7D%2A1.5%7D%7B0.1%2A10%5E%7B-3%7D%7D)
distance = 9.495 mm
Answer:
(a) A and B are similar but not congruent
Step-by-step explanation:
All of the rectangles have sides in the ratio of 2:1, so are all similar. Only the rectangles that are the same size are congruent: A and C.
A and B are similar, but not congruent.
