Which came first the chicken or the egg???

The egg that a chicken came out of was laid by a different type of bird (same species, just wasn't domesticated and wasn't known as a "chicken"), and the hatched bird was then domesticated, creating the modern chicken.

Lightning struck my house and now the speakers on my TV don't work very well. They work when someone is just watching TV , but when I try to use them for my Wii or my Xbox 360, all I get is silence and occasionally a slight droning. I've double-checked all the wires and they're definitely plugging in correctly. What do you think?

It might be that the Connectors in your TV have worn out or become damaged. It's obviously not your actual speakers, because they still work, so it must be the connectors that you plug your X-Box and Wii into. Might have to get a new TV, or get it repaired.

What is 3+3 reversed?

It depends on what you mean by reversed. If you mean opposite, then it would be 3-3. If you mean reversing the numerals within the equation, then it would be 3+3 still. If you mean reversing it mirror wise, then it would be E+E.

Very good.

 

In graph theory, what is a Star S7?

In graph theory, Star S7 are the non-isomorphic graphs. These are the types of graphs that possess a given property, in a given problem and are written in perms.

 

 

What is the acidity level of an average battery?

By acidity level do you mean PH balance? Because it would be about 1.5.

Why is ice slippery?

 

You must take into account that it is not always wet, and similiar surfaces are not....

 

Because of the diverse molecular structure of water as it freezes. As you know, when water changes state, it expands when it should be contracting. This is because of the six sided bonds the particles of ice and water make up.

 

But, that's irrelevant. Almost. The real reason, is actually that it is wet. You see, it is only slippery because it's a smooth or very near smooth surface, and also has low melting point and low mass. Now, it isn't slippery until you touch it. Here's why.

 

Your statement in your post is incorrect; ice is wet, once you step on it or touch it. Your body heat, which is much higher than the melting point of ice, melts the ice to create; that's right, water. This is what you slide on.

 

It's how skaters skate, and how you slip at a swimming pool, and how you slide on ice. All the same physics.

And yet, you disregard the fact that you can place an item onto the surface of ice that is the same temperature and it will slide. ie. The sole of a shoe exposed to the cold, those things used in curling, any other item..... Ice is still slippery.

 

There are three misconceptions. Ice is slippery not because it's smooth or because its melting point drops when pressure is increased (tennis shoes still slip the same as skates). In addition, friction melting the ice has nothing to do with the slipperiness of ice (people standing still slip).

 

The correct answer is that the surface of the ice has a microscopic film that is liquid-like. In a liquid, molecules are free to move around, but on the surface of ice, they move up and down. This also explains why when ice cubes are held together, they fuse. This was discovered very recently.

 

 

So close, but no go.
