The earth spins at approx 1000 mile per hour.

This is quite simple to calculate - the circumference of the planet is 24000 miles approx - and there are 24 hours in a day.

Eyes are able to focus when the Ciliary muscles attached to the lens adjust itself. They adjust itself so that the curvature of the lens varies according to where the light rays are coming from, so that it hits the retina properly to form a clear image.

As Newton's laws state, the greater the force, the more an object will accelerate or slow down. The force in the opposite direction of motion is called friction. So if you have a 3Kg block travelling at 2m/s, with a friction of 1m/s you will need at least 5N to keep it going. The more force you apply, the faster the block will travel, so it accelerates. The less force you apply the more it slows down and eventually stops because the friction is greater than the force applied. An object that travels in a uniform direction at a uniform speed (Newtons 1st law) will continue traveling in the same way and in the same direction (inertia) unless acted upon by a resultant force (friction).

the question is phrased poorly, but i think the answer is seven, as in white light is split into seven different wavelengths when passed through a prism.

Measure the vertical distance from the top of the water in the tank to the point of use. Multiply that distance by 0.44 to get the answer in psi.

Example: if the top of the tank is 20 feet above the point of use, the water pressure at the point of use will be 8.8 psi.

Note, this does not account for friction losses in the pipe. If the pipe runs a long distance from the tank to the point of use, there will be pressure losses in the pipe, especially if the pipe is a small diameter. The larger diameter, the less those pressure losses will be.

the world is upsidedown. A2. Well, the world is right way up, it is the sky (and stars) that are inverted. When the left half of the moon is bright as seen in the northern hemisphere, in the southern hemisphere it will be the right half that is bright

Greenhouse gases are very insulating, so when they float up to the atmosphere, they insulate the world. Sunlight and heat goes in through them, but more goes in than goes out. So gradually all the heat is being built up in the world. They are called greenhouse gases because they have the same effect on the Earth that a greenhouse has on the plants inside: it lets heat in but not out.

This is what is causing global warming.

air is not a mixture. it is a compound. it is made up of 1 oxygen atom nd 2 hydrogen atoms

Without a backbone that can bend, you would never be able to tie your shoelaces.

This question is too broad to be answered. Can you elaborate a little? For example, you might mean: Should government-funded researchers be held accountable? or Should medical trial research be conducted and evaluated by completely disinterested parties? or you might mean: Should scientific research be conducted under the direction of a religious authority?
