Physics - October 2006

Is it possible to take, for example, solar energy 'A' (that has already been stored) and magnify 'A' with further (new) solar energy ('B') to create more power than A and B would have if they were to just be combined normally? Sort of like a chemical reaction, perhaps?

To explain further, I would imagine that solar energy is built up to be one big energy in normal circumstances. (For lack of better way to explain.) However, would it be possible to store a certain amount of solar energy, then take some more energy from the sun and somehow take that energy and use it to increase the energy of the previously stored energy? And on and on until it's being magnified in large amounts as you collect small amounts of energy and magnify the energy you continue to store? ....

It's hard to explain! But I'm wondering if anyone knows if this is at all possible?

Why, then, doesn't a heavy body fall faster than a light body?

Why do both the sun and the moon exert a greater gravitational force on one side of the eath than on the other?

A force of 50N applied to the end of a lever moves that end a certain distance. If the other end of the lever is moved half as far, how much force does it exert?

I have been told that every body of matter (everything from the pencil I used to write this all the way to planet Earth) exerts a graviational-like force on every other body of matter. In other words: I'm somehow exerting a force on the computer screen that I'm using, not to mention everything else in this room.

But how does this theory fit in with Einsteins concept of gravity, where gravity is a direct result of the geometrical curvature of space.

A block of mass m = 3.00 kg situated on a rough incline at an angle of = 37.0° is connected to a spring of negligible mass having a spring constant of 100 N/m (Fig. P8.58). The pulley is frictionelss. The block is released from rest when the spring is unstretched. The block moves 13.5 cm down the incline before coming to rest. Find the coefficient of kinetic friction between block and incline.

the figure can be seen here >> http://www.webassign.net/sb5/p8-58alt.gif

I'm assuming I want to use conservation of energy, but I'm just not really sure how to get it started... any help would be appreciated.

...there is no collision occuring. Each point of the marble that touches the surface does so at almost zero vertical speed (the speed of the marble is going forward).

a factory worker pushes a crate of mass 29.5 kg, a distance of 4.8 m along a level floor at constant velocity by pushing horizontaly on it. the coefficient of kinetic friction between the crate and floor is is .258

what magnitiude of force must the worker apply and how much work is done on the crate by this force?

Light can be concentrated in to bright spot by using a lens.ie,light is 'intensified'.Similarly, is it possible to concentrate heat energy, say, by using a "thermal lens"?

For instance, in the theory of relativity where E=mc2, How is E measured. Let's say mc2 = 10 (just a made up number here). That would be 10 what? I can't just say 10 units of energy.

I'm a noob in Physics, so forgive me if this is a dumb question.

Also, are you a physics student, a professional physicist, or just an average person with an interest in physics. (Not that you're average person has an interest in physics mind you) ;)

It is known that the light and the heat of the waves that come from the sun, interacting with the microwaves coming from the waves of interstellar gases, supply the natural balance that gets to Earth every moment.
On the surface there are typical phenomena of elements that have instable atomic nucleus, a natural radioactivity. It artificially changes the radioactivity into an unbalanced condition, causing a cancerous nuclear reaction, phenomenon discovered years ago by the responsible for the nuclear science revolution, who, for considering it modern, discredited Earth’s modified radioactive unbalance. This vision opposes my consciousness, which only recognizes ethic and moral in science if based on natural scientific research, which may be accidental, criminal, professional or vicious, for the artificial exist to compromise life.

North Korea claims to have tested a nuclear bomb. I know that scientists will try to find out the truth of this by measuring the radioactivity in the atmosspere, but could they really see the difference between a real a-bomb and a conventional bomb with some added radiactive stuff.
