What is the difference between force and thrust ?
Asked by | 27 Mar, 2009, 10:11: AM
answered-by-expert Expert Answer

Thrust is a reaction force described quantitatively by Newton's Second and Third Laws. When a system expels or accelerates mass in one direction the accelerated mass will cause a proportional but opposite force on that system. Now,the force is equal to rate of change of momentum. Thus thrust is rate of change of momentum in the direction opposite to direction of motion, one of the characteristics being that usually thrust is accompanied  with change in mass.

The number of moles in an elemental sample is just the ratio of the mass m to atomic mass 4. n= A The number of protons N, in an elemental sample is Z (atomic number) times the number of moles of Avogadro's number NA N=ZnN P A Copper has an atomic mass of 63.5 g/mole and 29 protons per atom. If such an atom were neutral, then it would have as many protons as electrons. If you remove electrons from a neutral state, then you get a net positive charge. Given a 54 gram ball of copper with a net charge of 2.2 µC, what fraction of the copper's electrons have been removed?
