This is question four!!!!!

4. Does your flashlight dim when you shake it?

Come on, you were a kid once. I dare say that everyone was facinated by a flashlight at some point in their lives and played with one for hours on end. That is, of course, until the batteries ran out, at which time the flashlight wasn't very facinating at all.

Well, what i'm wondering is, while the batteries were dying and the light was much dimmer than it would be if the batteries were full power, whenever you shook the flashlight, did it dim even more, only to return to it's original state of dimness whenever you stopped?

Believe it or not, the findings of this question actually have a practical value.

II personally can not believe in it because there are really some things which do not make sense.
I think it is time to find a new theory for that.
Anybody else?

I'm working with an electrical enginier and we are consturcting a control panal, we have a item that we are controling with 4 diffent swithes that each have 3 positions. We were wondering how many possibilites there are for someone to mess these controls up. Could some one please help us and give us the formula for figuring this out. THANK YOU

This is the third question in I'm not sure how many of a probe into the behavior of electricity. I intend to use the findings later to test another theory.

3. Is the flow of electric current affected by temprature?

These questions are pretty straightforward. We've all heard of resistance, measured in Ohms. Well, what I'm wondering is does electricity travel as well in cold enviornments as hot enviornments? That is to say, do they need special cables in Alaska to make electricity flow from the power plant into all of those little igloos, or do they need special cables in the deserts of Arizona and Nevada to keep Las Vegas lit up all night long? I suppose that it would be just as relevant if the effects of temprature on the wires would cause changes in the behavior of the current, too.

Now, keep in mind, I'm not asking if the current reverses or comes flying out of the side of the wires, mind you. I just wonder if it speeds up or slows down. Even by the most minute degree.

Multiply.
1. 9 x 10 to the 4th power

Find each product
1. 136 x 10 to the 2nd power

Write in scientific notation
1. 65,000

1. In 1930, the world population was about 2,000,000,000. In 2001, the world population was about 6,200,000,000. About how much did the world population increase between 1930 and2001?

In the last 100 years the average global temperature has increased by less than a single degree Celsius.

Between 1940 and about 1980, the average global temperature decreased.

The average global temperature today is NOT as high as it has ever been. The Paleocene-Eocene Thermal Maximum event 55 million years ago caused sea temperatures to increase by up to 8 degrees Celsius, leading to mass extinctions.

Here are the data:

have you ever thought what "nothingless"means?! In my opinion there is nothing such a nothingless, at least I can't ever imagin that. there must be something!

I don't know if Apes have them, but it seems as if there is no real practical application for them (maybe better grip?) but what is more weird about them is that no two are the same, it just seems real strange why evolution would do this.

In simple terms Men are from Mokeys.Then why the rest of monkeys remained as monkeys?Why fishes remaned as fishes?Why birds did not become fishes?
How come man as the only exception to go through all these so called evolution?

I am making a camera setup where a webcam is being used with a 35 mm telephoto lens. In the process the stock lens for the webcam was removed. This stock webcam had a lens with a coating that blocked infrared light. Without this the colors are skewed. What I need is a cheap way block this infrared light but without distorting the image. Photo shops sell filters for this purpose.. but they cost as much as the webcam 100$ or more.
