Simply by observing the existence of the Cherenkov radiation from a particle, one can determine its relative velocity with respect to the light speed in medium. Knowing that, one can determine the particle momentum.
It is a ring formed carbon skeleton. The smallest possible cyclic hydrocarbon is cyclopropane (triangular C3H6) together with cyclobutane both being rather unstable (degration to linear propene and 1-butene). Five and six membered rings are quite common.
 A hydrocarbon is a molecule that consists primarily of hydrogen and carbon. Other atoms may be present in place of the hydrogen atoms in some places. Examples of hydrocarbo â¦ ns include Methane (CH4), toluene.A hydrocarbon contains only hydrogen atoms and carbon atoms.There are a large number of hydrocarbons, but the simplest is CH4 (methane). One important thing about hydrocarbons is that they are all flammable.A hydrocarbon is a molecule that consists primarily of hydrogen and carbon.
