What must be the angle between the direction of propagation of the incident and scattered photons if the speed of the electron immediately after the collision is 9.90×106m/s?

c.the charges if the proton and electron and gravity

choosing tennis and golf balls is your inde choice.

their mass and volume are dep

  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

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
