Answer:
Action and Reaction
Explanation:
For every force, there is one of equal and opposite also. Think of it this way. When you try to push on a wall, you are applying a force. However, that wall is also pushing back on you with that same force. You can also see this when you high five someone. You can slap as hard as you want to their stationary hand, but due to the 3rd law, you're both going to be left with red hands do to the amount of force applied.
Answer: Particles cannot bend around the edges of an obstacle, as light waves does.
Explanation:
Diffraction happens when a wave (mechanical or electromagnetic wave) meets an obstacle or a slit .When this occurs, the wave bends around the edges of the obstacle or passes through the opening of the slit that acts as an obstacle, forming multiple patterns with the shape of the aperture of the slit.
Note this phenomenon is a characteristic of waves behaviour and not particles, because <u>particles cannot bend around the edges of an obstacle</u>, as waves (light waves in this case) does.
So that international people don't mistake units for others. ex 1 inch could be mistaken for 1 cm in non American countries
Thus, area is the product of two lengths and so has dimension L2, or length squared.
