The frequency of the
scattered photon decreases or it will be lower compare to the frequency of
incident photon. An x-ray photon scatters in one direction after a collision
and some energy is transferred to the electron as it recoils in another
direction resulting to have less energy in the scattered photon. In addition, the
frequencies will also depend on the differences of the angle at which the
scattered photon leaves the collision and this incident is called Compton Effect.

Find your element
Locate the element atomic number
Determine the number of electrons
Look for the atomic mass of the element
subtract the atomic number from the atomic number
Answer:
the standard metre is the length of path travelled by light in vacuum during interval of time of a second
Answer:
The value is
Explanation:
From the question we are told that
The mass of the sphere is m = 18.5 kg
The diameter is
The number of electrons is
The mass of the plastic ball is
The initial acceleration of the ball is
Generally the radius of the sphere is mathematically evaluated as
=>
=>
Generally the force between the ball and the sphere is
Generally this force can also be mathematically represented as
So
Here is the charge removed from the sphere whicn is evaluated as
substituting for e
and is the charge to be removed from the ball
So
Generally the number of electron to be removed from the ball is mathematically represented as
=>
=>
Answer:
3. Silver tarnishes when exposed to air and light
Explanation:
Physical properties are properties that change substances in ways that is visible to a human by using their senses (ie. see, touch, etc)
The rest of the answers are chemical properties, which cannot be seen with the human senses, and requires other special devices or techniques to tell.
