I believe destructive interference.
EXPLANATION: when two waves meet and a crest of one wave is parallel to the crest of another destructive interference occurs. You subtract the amplitude of the two waves that meet and you’ll get the amplitude of the wave they’ll form. If it is the same amplitude the result will be zero.
Hope this helps
Answer:
Slightly above 20°c
Explanation:
The resistivity of silver is 1.59 x 10-8Ωm{ as discovered by experiment from scientist}
The resistivity of tungsten at 20°c is 5.6x10-8Ωm
We see the value is just an approximation of 4 times not exactly.
This is because metal is a conductor of electricity while rubber is not (rubber is an insulator). Therefore the metal is more amenable to 'ground' the high charge in the lightning than rubber would. This is also why, when lightning strikes metal, it is safely 'grounded' while if it strikes a non-conductor, most occasionally, it explodes into a fire.
Everything with 1 symbol = Element
Everything with multiple symbols = Compound
Elements are the smallest particles (if we go further things start to get weird). Compounds are ALWAYS made up from elements.
Both answers are true. Things like basic quantum mechanics helped us better our technology like iPhones. And the second option explains itself. We get to understand the universe better and predict phenomena when we learn more about any Physical Science
