34. The element would have 34 protons. Also 34 electrons.
As the boulder falls off the cliff, the gravitational potential energy that the boulder has is converted into kinetic energy. If you do the calculations, you will see that the kinetic energy the boulder has is equal to the gravitational potential energy it had before it fell off a cliff.
Answer:
so your answer is gonna be the first one which is A
If the wavelength increases (gets longer), then the frequency <em>decreases</em>.
(A wave occurs less often.)
Angle of incidence is the angle when the light strikes an object while angle of reflection is the angle produced when the light strikes off/reflects from the object.
The relation between these two is that both the angles are equal.
The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.
Hope this helps!
