In the Compton effect, the wavelength of the scattered photon is __________ the wavelength of the incident photon.
SOVA2 [1]

Answer:

he wavelength is different (greater) than the wavelength of the incident photon

Explanation:

The Compton effect is the scattering of a photon by an electron, this process is analyzed using the conservation of momentum, in which we assume that initially the electron is at rest and after the collision it recedes, therefore the energy of the incident photon decreases and consequently its wavelength changes

To complete the sentence we use the wavelength is different (greater) than the wavelength of the incident photon

A worker pushes a 1080 N crate with a horizontal force of 345 N a distance of 14 m. Assume the coefficient of kinetic frictin be
amm1812

Answer:

The work done by the worker on the crate is 4830 J.

Explanation:

Given that,

Force = 1080 N

Horizontal force = 345 N

Distance d = 14 m

Coefficient of friction = 0.22

We need to calculate the work done

Using formula of work done

W = Fd

F = force

d = distance

Put the value into the formula

W=345\times14

W=4830\ J

Hence, The work done by the worker on the crate is 4830 J.

An earthquake in San Francisco produces a wave with a period of 0.80 seconds and a wavelength of 40 m., How long will it take fo
gtnhenbr [62]

Answer:

A) 3.11 Hrs

Explanation:

Wave speed is given by the formula

Speed = \frac{wavelength}{Time\: period}

now we will have

speed = \frac{40}{0.80}

v = 50 m/s

now the time taken by the wave to move the distance 560 km is given as

t = \frac{distance}{speed}

t = \frac{560\times 10^3}{50}

t = 11200 s

t = 3.11 hours
