No device uses "kilowatts per hour". A watt or kilowatt is a unit of power, not of energy. That means that the "per hour" or "per second" is already implied - the watt refers to a "rate of energy conversion" - not to an amount of energy. If a devices uses a certain amount of kilowatts, it uses this amount all the time while it is on - whether it is kept on for a second or for several days.

Why does a ping pong float with a hair dryer?
When you point a running hair dryer upward, and place a ping pong ball in the air stream, it will eventually float somewhere above the hair dryer and near the air stream. It stays above the dryer because the drag of the air balances out the ball's 2.7 grams of mass, and near the air stream due to the Bernoulli effect. The Bernoulli effect is the drop in pressure when a fluid's velocity increases; you can demonstrate it by blowing over the top of a piece of paper. It is partly responsible for the lift generated by an airplane's wing. The ball is drawn towards the center of the air stream due to the increasing velocity and the resulting Bernoulli force, but is pushed away by the air glancing off its surface. The ball maintains a position where these forces balance out, perhaps wobbling back and forth so the average forces balance out.
What is the climate like in LA?
It is hot, hot, hot during the day(95-110F) and very dry(it feels like putting a hair dryer in front of your face) but it cools down considerably in the evening.
Is meticulous a verb?
Meticulous is not a verb, it is an adjective. She spends hours readying herself for a date. Her makeup is perfectly applied, not a hair is out of place, not a wrinkle on her clothing. She is meticulous about her appearance.
My mom n i have dark brown hair my dad has black hair both my grandparents have dark hair my boyfriend n his sister have light brown hair n his mom has blond hair what color hair will the baby have?
If the females parents both have dark brown hair and the males parents both have light brown hair, their is a 50/50 chance of having either colour hair. Although if that is not the case, the child could have blonde hair if one of the grandparents has blonde hair also, there is not a definite hair colour. It is all down to chance.
Can a newborn baby hair turn black if born with dark brown hair if dad has black hair and mom has brown hair?
Yes. The color of a newborn's hair can be different (almost always lighter) than the eventual adult hair color.
