Skin depth depends on the frequency of the alternating current; as frequency increases, current flow becomes more concentrated near the surface, resulting in less skin depth. Skin effect reduces the effective cross-section of the conductor and thus increases its effective resistance. At 60 Hz in copper, skin depth is about 8.5 mm.
A man is filing a lawsuit against Walmart claiming that numerous items were more expensive at checkout than what was advertised on the shelf.
Day for night is a set of cinematic techniques used to simulate a night scene while filming in daylight. It is often employed when it is too difficult or expensive to actually shoot during nighttime.

Some processes propagate faster than c, but cannot carry information (see examples in the sections immediately following). In some materials where light travels at speed c/n (where n is the refractive index) other particles can travel faster than c/n (but still slower than c), leading to Cherenkov radiation (see phase velocity below).
He goes, ‘Come outside, I need to talk to you,’ and I go, ‘No.’ I said, ‘You need to tell me,’ and he said, ‘Dad had a heart attack, and he died.’ “It was like you couldn’t ...
