In a road accident where one car has stuck to another on collision, accident investigators often measure the length of skidmark produced from where the vehicles collided. The mass of the two cars and the deceleration produced by the road are also measured. How can these figures be used to calculate the velocity of te cars before collision? I got this question as homework after having had a Physics lesson on Momentum. Any help will be very much appreciated. Thanks.

Guys look in nuclear fission involves in breaking of a heavier nucleus into lighter nuclei and in doing this the binding energy of nucleus is lost and hence enormous amount of energy is lost and i can understand that, but in nuclear fusion two or more nuclei combine to form a heavier nucleus and hence the binding energy should be acquired but rather its released, howcome this happens and i know that nuclear reactions occur in stars and the temperature required for the reaction is found to be of order 10 power 6 and during the beggining of formation of star, how did it attain that high temperature and it is easy to understand high temp. of stars coz of the energy released during fusion, however it is and one more doubt give me an example of fissile material apart from Uranium - 235 and 100% to points for the best answer. Thanks for answering if answered and hope for good answers coz i wud like to understand the subject.

Consider two point charges of the same magnitude but opposite sign (+Q and -Q), which are a fixed distance d apart. Can you find a location where a thir positive charge Q could be placed so that the net electric force on this third charge is zero? What if the first two charges were both +Q?

Gravity is also known as acceleration due to gravity (g) and is 9.81 m/s^2 but usually we take it as approximatly 10 m/s^2. I have this in my Physics notes and I can't figure it out!!!!!
