The cowardly European policy causes approach of Russian tanks to their borders.

Ukraine needs necessary weapon against Russian tanks.

No knowledge and no understanding in the case. Therefore they are equal in your case.

Any discovery is magic. Of course we don't know abilities of scientists. For example bomb which can detonate weapon.When you have no weapon then it is safe for you.

Then did you define that a necessary weapon should kill everyone?I only told that physicists should create necessary weapon.

No. That's brilliant example when physicists create necessary weapon.

Because I don't want to be the feet. And remember Japan. I don't offer to use nuclear weapon, but we should improve our weapon.

Successful air strikes can make win when they are sufficient. Feet can't when they are without rockets and air strikes.

Expansion of space exists. And galaxy clusters feel its force.

Don't forget that methanol evaporates first.

Then, I think, Gravitational Force=5Gm2/r2 r1=[5Gm/(c2*cosmological constant)]1/3 and r2=[5G(m/2)/(c2*cosmological constant)]1/3 r1/r2=21/3 v=x3r13=2x3r23 Quantity of first objects~x3 Quantity of second objects ~2x3 mass of first objects in the volume=x3m mass of second objects in the volume=2x3m/2=x3m

Russian government promises to reduce price of vodka for consolidation of folk against USA and Ukraine. Not all is so bad in Russia.

My opinion is unchanging independently of senseless hopes.

Money should work then they are money. When peace people don't offer a benefit of peace development then military business take free money for military development. Make your peace offers for benefit and development.

Increasing of quantity of your enemies reduces your development not always. We don't need love idiocy because we don't need look good for idiots when we do development.

Our attention should be dangerous for terrorists. If it is attractive for them then our attention should be more dangerous for them.

Let's imagine infinite quantity of identical objects, which are in identical intervals located in space. Where forces of cosmological expansion are neutralized by forces of gravity. And forces of gravity are neutralized by cosmological force. Where is mass of all the objects in big volume more: when mass of of one object = m or when mass of one object = m/2 ?

Pride for identity should be punished. Cartoons of JesuisCharlie are the good punishment .

Decipher please questions of OP.

Resistance to violence.

Thank you very very large. If m=1 kg then R=281374807 m. Less than 1 light second.

Distance between two bodies = R mass of first body = m mass of second body = m kinetic energy of any body of the two bodies relative to each other = 0 cosmological force of space expansion = F gravitational force between the bodies = F There is no another force. How to define R ?

m1=200kg m2=150kg u1=5 m/s u2= -5 m/s v1 is speed of car A after collision v2 is speed of car B after collision Can you use some equations?:http://en.wikipedia.org/wiki/Elastic_collision http://en.wikipedia.org/wiki/Inelastic_collision
