X-rays with an energy of 400 kev undergo compton scattering with a target. if the scattered x-rays are detected at \theta = 30^{\circ}θ=30 ∘ relative to the incident x-rays, what is the energy of the recoiling electron?

The energy of recoiling electron=192.44 keV

Explanation:

Energy of x-ray

Web know that compton shift is

is the mass of electron and C is the velocity of sound.

Given that θ=30°

Now by putting the values

By putting the values

Energy

So

E=207.55 keV

The energy of recoiling electron=400-207.55 keV

The energy of recoiling electron=192.44 keV

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
