They're clear, yeah? So why would they cast a shadow?

Methinks it has something to do with light refraction, but I'm not sure...

Liquid mercury is definitely conductive.

It is also possible to 'convert' liquid mercury
into gaseous phase without any phase
transitions, just turning over its critical point.

What's more likely to trip the breakers?

1. My 3000 W, 9 A airconditioner
2. Two 1500 W, 12 A space heaters running simultaneously

Please explain whether it's the wattage or the amperage that should be taken into account.

An arrow, starting from rest, leaves the bow with a speed of 30.0 m/s. If the average force exerted on the arrow by the bow were doubled, all else remaining the same, with what speed would the arrow leave the bow?

A jet powered plane is standing on a movable runway (something like a giant treadmill). As the plane moves the treadmill moves but in the opposite direction. The treadmill has a system that tracks the speed of the plane and matches it exactly in the opposite direction.

The question is: Will the plane take off or not?

All Forces such as wind resistance and friction are not counted.

Think carefully...

A closed 55.0 gallon drum is a 91.0 -long, 59.0 -diameter cylinder with flat ends that is made with 17.0 of sheet metal. If the thickness of the ends is the same as that of the curved sides, what is the moment of inertia about an axis that runs down the center of the drum? The uniform thickness of the sheet metal will allow you to determine the mass of the ends and the mass of the cylinder. What fraction of the surface area of the drum is associated with its ends?

radiation is actually the smallest form of matter
due to it speed its gravity influences other matter multiply times in the same instance giving it the illusion of being a wave
the smaller the mass of the radiation the bigger the frequency because it is influenced more by the matter around it
the larger the mass of the radiation the longer the illusion of a wave length because it influences the matter around it more
radiation is a result of deterioration of sub atomic particles and atomic particles
it travels in a wave like pattern due to the attraction of electron pulling it in one direction but when the electron moves to the far side of the protons the protons push it away
this is also why its acceleration changes depending on the medium it is travelling through
radiation also has the ability to cause subatomic and atomic particles to become unbalanced(leading to more radiation) if the electrons are unable to obtain a higher orbital path to compensate for the radiations gravity
this is my theory on radiation and is not considered common believe so if the question is for school choose an answer that is more commonly believed (which would be a)

(currently working on my 2 forces theories)
