Answer: 150 miles per hour
Explanation:
600/4 just do 600÷4 on a calculator and you will get 150 miles.
Answer:
the extension would be less the new extension might be 3 cm
Explanation:
You're most likely to build up enough static charge to receive a shock by walking around in a carpeted restaurant in the desert. (A)
Walking on carpet is the fastest way to accumulate charge, and the dry desert air prevents the charge from dribbling off of you and away.
When I walked on stones in the Sinai Desert, the dry wind with a little bit of sand or dust in it built up enough static charge on me that I got a shock every time I stood less than a foot away from my partner.
I had the same experience a few years later near Ouarzazate in the interior of Morocco.
When you hear people say "the desert is dry", they mean it's <em>DRY ! </em>
