A pair of slits in a double slit experiment are illuminated with monochromatic light of wavelength 480 nm. The slits are separat

Romashka-Z-Leto [24]

Using the appropriate approximations:

dx/L = mλ

d = slit separation

x = fringe spacing

L = distance between slits and screen

m = some integer, used to determine the distance from the central bright fringe to another bright fringe

We don't really need a value for m because we're calculating the distance between any pair of consecutive fringes. Let's just set m = 1

Given values:

d = 1.0mm

L = 2.0m

λ = 480nm

Substitute the terms in the equation with our given values and solve for x:

1.0*10⁻³*x/2 = 480*10⁻9

<h3>x = 0.96mm</h3>

It has been suggested that rotating cylinders about 9 mi long and 5.9 mi in diameter be placed in space and used as colonies. Wh

mezya [45]

Answer:

$\omega = 4.5\times 10^{-2} rad/s$

Explanation:

Given data:

Rotating cylinder length = 9 mi

diameter of cylinder is 5.9 mi

we know that linear acceleration is given as

a = r ω^2

where ω is angular velocity

so $\omega = \sqrt{\frac{a}{r}}$

$r = \frac{5.9}[2} \frac{1609 m}{1 mi} = 4.746\times 10^{3} m$

$\omega = \sqrt{\frac{9.80}{4.746\times 10^{3}}}$

$\omega = 4.5\times 10^{-2} rad/s$

You are helping your friend move a new refrigerator into his kitchen. You apply a horizontal force of 275 N in the positive x di

Volgvan

Answer:

f = 347.08 N

Explanation:

The frictional force exerted by the floor on the refrigerator is given as follows:

$f = \mu R = \mu W$

where,

f = frictional force = ?

μ = coefficient of static friction = 0.58

W = Weight of refrigerator = mg

m = mass of refrigerator = 61 kg

g = acceleration due to gravity = 9.81 m/s²

Therefore,

$f = \mu mg\\f = (0.58)(61\ kg)(9.81\ m/s^2)\\$

<u>f = 347.08 N</u>
