In a double-slit experiment, the slits are illuminated by a monochromatic, coherent light source having a wavelength of 507 nm.

An interference pattern is observed on the screen. The distance between the screen and the double-slit is 1.32 m and the distance between the two slits is 0.112 mm. A light wave propogates from each slit to the screen. What is the path length difference between the distance traveled by the waves for the fifth-order maximum (bright fringe) on the screen

Answer:

The path difference is 2.53 \times 10^{-6} m

Explanation:

Given:

Wavelength of light \lambda = 507 \times 10^{-9} m

Distance between slit and screen D = 1.32 m

Distance between two slit d = 0.112 \times 10^{-3} m

Order of interference n = 5

From the formula of interference of light,

   d\sin \theta = n\lambda

Where d \sin \theta = path difference, n = order of interference

Here we have to find path difference,

 Path difference = 5 \times 507 \times 10^{-9} m

 Path difference = 2.53 \times 10^{-6} m

Therefore, the path difference is 2.53 \times 10^{-6} m

A bicyclist is traveling at a speed of 20.0 m/s as he approaches the bottom of a hill. He decides to coast up the hill and stops
Rudiy27

Answer:

Vertical height of the hill, h = 20.4 meters

Explanation:

Given that,

Speed of the bicyclist, v = 20 m/s

To find,

The vertical height of the hill.

Solution,

Let h is the height of the hill. When he approaches the bottom of the hill, the loss in kinetic energy is equal to the gain in potential energy. Using the conservation of energy as,

\dfrac{1}{2}mv^2=mgh

h=\dfrac{v^2}{2g}

h=\dfrac{(20)^2}{2\times 9.8}

h = 20.4 meters

Therefore, the vertical height of the hill is 20.4 meters. Hence, this is the required solution.

nordsb [41]

Answer:

<h2>1320 J</h2>

Explanation:

The work done by an object can be found by using the formula

workdone = force × distance

From the question we have

workdone = 600 × 2.2

We have the final answer as

<h3>1320 J</h3>

eduard

Answer:

the magnetic field is leaving the sheet

Explanation:

The magnetic force is given by the expression

        F = q v x B

where bold letters indicate vectors, the modulus of this expression is

       F = q v B sin θ

the direction of the force is given by the right hand rule, for a positive charge

the thumb indicates the direction of the speed, in this case from right to left

the palm the direction of the force, in our case upwards

the fingers extended the direction of the magnetic field, this case after fixing the other two components it points out of the blade

In short the magnetic field is leaving the sheet

Miss Piggy is exercising her vocal chords by matching the frequency f = 686 Hz of her speaker 4 m away. Where should Kermit sit
monitta

Answer:

z=\frac{2n+1}{8} for n=0,1,2,3,...,15

Where z=0 m is the position of Miss Piggy and z=4 m is the position of the speaker.

Explanation:

Assuming that Miss Piggy emits a sound wave that is in phase with the speaker, and that z=0 is the position of Miss Piggy and z=4 is the position of the speaker, we would have a superposition of two traveling sound waves. Furthermore let's assume that both waves have the same amplitude. The total resulting wave will be given by:

\psi(t,z)=A\cos(\omega t-kz)+A\cos(\omega t +kz) where \omega is the angular frequency of the traveling wave and k is the wave number defined as k=\frac{2\pi}{\lambda}. \lambda is the wavelength of both traveling waves (they have the same wavelength because they have the same frequency). \lambda=\frac{v}{f} where v is the speed of sound.

By using the trigonometric identity 2\cos(A)\cos(B)=\cos(A+B)+\cos(A-B) we can rewrite \psi (t,z) as

\psi (t,z)=2A\cos(\omega t)\cos(kz).

In order for the resulting wave to have maximum destructive interference, that is to be zero for any time t, we need to have

\cos(kz)=0

\implies kz=(2n+1)\cdot \frac{\pi}{2}\implies z=(2n+1)\frac{\pi}{2k}=(2n+1)\frac{\pi}{2}\frac{\lambda}{2\pi}=(2n+1)\cdot \frac{\lambda}{4}

\implies z=(2n+1)\cdot\frac{v}{4f}=\frac{2n+1}{8}
