A velocity selector can be used to measure the speed of a charged particle. A beam of particles is directed along the axis of th

e instrument. A parallel plate capacitor sets up an electric field E which is oriented perpendicular to a uniform magnetic field B. If the plates are separated by 3 mm and the value of the magnetic field is 0.3 T, what voltage between the plates will allow particles of speed 5 x 105 m/s to pass straight through without deflection? A. 70 V B. 140 V C. 450 V D. 1,400 V E. 2,800 V

In a solution if substance A makes up 1%, substance B makes up 9%, substance C makes up 20% and substance D makes up 70%, which
SIZIF [17.4K]
From the description of the substances, the best answer would be option A. Substance D would generally function as a solvent because it has the largest composition in a solution. A solvent in a solution has the highest percent composition among all components involved. Having a composition of more than 50% would mean that a substance is the solvent.
