Parallel rays of monochromatic light with wavelength 583 nm illuminate two identical slits and produce an interference pattern o

romanna [79]

Answer:

I = 2.18 10⁻⁴ W / m²

Explanation:

The two-slit interference pattern is described by the expression for constructive interference.

d sin θ = m λ

If we also want to know the distribution of intensities we must perform the su of the electric field of the two waves, and find the intensity as the square of the velvet field, obtaining the expression

I = I_max cos² ((π d /λ L) y)

where d is the separation of the slits, λ the wavelength, L the distance to the screen e and the separation of the interference line with respect to the central maximum

let's reduce the magnitudes to the SI system

λ = 583 nm = 583 10⁻⁹ m

L = 75.0 cm = 75.0 10⁻² m

d = 0.640 mm = 0.640 10⁻³ m

y = 0.900 mm = 0.900 10⁻³ m

let's calculate the intensity of this line

I = 5 10⁻⁴ cos² ((π 0.640 10⁻³ /583 10⁻⁹ 0.75 10⁻²) 0.900 10⁻³)

I = 5 10⁻⁴ cos2 (413.84)

I = 5 10⁻⁴ 0.435

I = 2.18 10⁻⁴ W / m²

The moon's gravity is one-sixth that of the earth. what is the period of a 2.00m long pendulum on the moon

erik [133]

Answer:

6.96 s

Explanation:

The period of a simple pendulum is given by:

$T=2 \pi \sqrt{\frac{L}{g}}$

where

L is the length of the pendulum and g the acceleration due to gravity.

In this problem, we have a pendulum with length L = 2.00 m, while the acceleration due to gravity is 1/6 that of the earth:

$g' = \frac{g}{6}=\frac{9.8 m/s^2}{6}=1.63 m/s^2$

So, the period of the pendulum on the moon is

$T=2 \pi \sqrt{\frac{2.00 m}{1.63 m/s^2}}=6.96 s$

a car dealer sells 4 makes of cars in 5 colors with either standard or automatic transmissions. how many variations does the dea

Anuta_ua [19.1K]

<u>The number of variations the dealership have is 40 cars</u>.

Data given;

The number of different product = 4
The number of transmission = 2 (standard or automatic)
The numbers of colors available = 5

<h3>Dealership variation </h3>

This is the total numbers of cars available in the dealer shop at the moment.

To get that, we simply multiply the numbers of colors available, the number of transmission and the makes of car available.

This is equal to

$4*2*5=40$

From the above calculation, we can say that <u>the variations the dealership offers is 40</u>
