And a dealer would say 8 cents, or even less!
Refraction occurs at each surface, and as the degree of bending depends on wavelength, the light is dispersed into a spectrum. Red is bent less than blue
The word voltage is used colloquially to describe two different things. The first is electromotive force or e.m.f. Of a battery, cell or generator, which is the energy converted into electrical form per unit charge passing through the device. The other is the potential difference or p.d. Between two points in a circuit, which is the … Read more
Diamond is one of the most refractive materials that is transparent, although the highest for which I have seen a value is silicon.
You can find the refractive index of opaque materials by studying the angle at which reflected light is almost totally plane polarised (Brewster's Law)
Most meteorites are relatively small, so they would have little effect on the much more massive Moon. It would take an enormous asteroid to have a significant effect - Ceres is the largest and even that would cause little deflection. However, the view from Earth would be spectacular. There is evidence that in Anglo-Saxon times some monks saw … Read more
They burn, forming carbon dioxide and water.
What is the question?
The former has a MA greater than 1
The latter has a MA less than 1
You can charge an object by connecting by a wire to something at a high voltage.
This is charging by conduction.
If you bring a charged object near a conductor, briefly touch the conductor, and then remove the charged object, the conductor will have a charge left on it. This is charging by induction (in case … Read more
I have both a 6 inch ruler and a very useful 18 inch ruler (You know how often 12 inches is not quite long enough)
If by that you mean 1997 two pound coins, the answer is not more than 2 pounds if circulated.

20 pence seems to be the most obvious answer. Even uncirculated 20p coins have little value.
Ten pence if circulated
