B. Move from their ground states up to excited states
:)
The phenomenon which is responsible for this effect is called diffraction.
Diffraction is the ability of a wave to propagate when it meets an obstacle or a slit. When the wave encounters the obstacle or the slit, it 'bends' around it and it continues propagate beyond it. A classical example of this phenomenon is when a sound wave propagates through a wall where there is a small aperture (as in the example of this problem)
Answer:3.33x10^(-17)
Explanation:
Period=wavelength ➗ velocity
Period=1/10^8 ➗ (3x10^8)
Period=3.33x10^(-17)
the see-saw, and the catapult.
Answer:
Muscular Force = Uses when walking
The Force of wind = Force used to turn a windmill
Force of Gravity = Used to drag thing to the centre of the earth
Steam = Type of force used to operate machines
Work = Amount of force Times the distance moved
Foot - Pound = Moving one pound one foot
Newton meter = moving one newton one meter
