Answer:
Where is question 12, we need it to answer this question
Explanation:
Answer:
v = 0.375 m/s
Explanation:
Given that,
The wavelength of a wave is 0.75 m/cycle
The period of a wave is 2s/cycle
We need to find the speed of the wave. We know that,
Substitute all the values,
So, the speed of the wave is equal to 0.375 m/s.
Position displacement velocity acceleration are vectors and the rest are scalars
Well, I think it kinda depends on how long the "extended period" is.
If the extended period is a week, a month, or a few months,
then I'd call it a 'cold wave'.
If the extended period is like 100 years or more, then you're
starting to talk 'ice age'.
Well, let's take it the other way. If you have a rather low voltage (220 volts -- Europe -- is low) you'd get a high current, which more easily dissipates as heat, resulting in loss of energy. Using a high voltage you have a low current which could easily be transported with almost no loss.
