I have looked all over the place. I am wanting to reduce the compression chamber for torque gains if it is worth it. Please help.

Ive seen this question posted lots of different times by different people. Right up front I say it is interesting to thing of our solar system as an atom.

They atom has the middle called the nucleus which is made up of protons and neutrons.

Orbiting all around the nucleus is electrons. Kind of like our plantes orbit around the sun. So the very building blocks that make up matter looks like our solar system.

I bought into this until I came upon what is called an ionized atom.

of course that means two atoms of different elements for what is called a compound and they electrons move right out of one atom into another.

Kind of reminds me how our moon is moving further away from us each year. Or is it being pulled away by another universe or (atom).

Anyone else find this interesting at all.

Also please forgive my spelling im bout to fall asleep and its like 2am in the morning.

Would plants grow taller on the moon? Yes, I know there is no air on the moon. It would be in a greenhouse or something. Would they grow a little taller, six times as tall, or about the same?

What are the alternatives to oxygen as far as respiration for a life form? I know all animals need oxygen. What about anaerobic bacteria? Do they need any type of gas to breathe?

There's like a huge circle around it. Go outside and look at the moon and tell me what's going on! It's really neat.

You know the big spot lights you see in the sky. Can you make one out of LED lights? If so can you have different colors like red and would it be cheaper to run?

In 1977, I was driving up Wilshire Blvd. in Los Angeles, and (at the time I didn't know this but figured it out after the fact) I somehow drove through a "time portal" or somehow entered a "parallel time dimension" and found myself in the FUTURE.

I was simply bewildered over this twin tower skyscraper finished in a gold mylar glass... and the astonishing thing about this structure was the "central span" which crossed over Wilshire and connected the North Tower with the South Tower... it wasn't merely a pedestrian bridge or mezanine, but an entire building as thick as the tower were wide, but turned on its side, and even the bottom surface was finished in this beautiful golen mylar.

The structure was located EAST of the Harbor Freeway EAST of downtown LA directly on Wilshire, and today, 29 years later, no such building exists there in this location.

As I drove beneath the central span, I purposely slowed down to absorb the details... I saw people entering the revolving doors.

If there's no light, then there's no sun. If there's no sun then there's no heat. If there's no heat, there's no water. At least not liquid water. Clearly it reads moved upon the face of the waters and not ice. Just curious as to why that is.

A home-based company produces both hand-knitted scarves and sweaters. The scarves take 2 hours of labor to produce, and the sweaters take 14 hours. The labor available is limited to 40 hours per week, and the total production capacity is 5 items per week. Write a system of inequalities representing this situation, where x is the number of scarves and y is the number of sweaters.

A thin, uniform, metal bar, 2.5 long and weighing 70 , is hanging vertically from the ceiling by a frictionless pivot. Suddenly it is struck 1.6 below the ceiling by a small 3-kg ball, initially traveling horizontally at 13 . The ball rebounds in the opposite direction with a speed of 6 m/s.

Find the angular speed of the bar just after the collision
