An electron is carried from the positive terminal to the negative terminal of a 9 V...
The anode (positive terminal) of an X-ray tube is at a potential of 120,000 V with respect to the cathode (negative terminal). How much work (in Joules) is done by the electric force when an electron is accelerated from the anode to the cathode? If the electron is initially at rest, find the speed of the electron when it arrives at the cathode. (e = 1.6 * 10^-19 C, me =9.1 * 10^-31 kg)
How much work must we do on an electron to move it from point A, which is at a potential of +50V, to point B, which is at a potential of -50V, along the semicircular path shown in the figure? Assume the system is isolated from outside forces (e = 1.60 times 10^-19C) 1.60 times 10^-17 J -1.60 times 10^-17 J 1.6 J -1.6 J This cannot be determined because we do not know the distance traveled. If an electron...
The positive and negative terminals of a 9 volt battery are about 1 cm apart. If proton is released at rest from the positive terminal of a 9 V battery, how much kinetic energy does it have just before it strikes the negative of the battery? A. None, it's kinetic energy has been used up. B. 6.8 x 10-27 J C. 9.0 eV D. 1.4 * 1020 J E. 1.4 * 1022 J I think there could be two answers,...
How much work is done to move an electron with a charge of –1.6 × 10–19 C from the positive terminal of a 1.5-V battery to the negative terminal?
A positive current of 2.00 A flows from the negative to the positive terminal inside a battery that has an emf of 10.0 V. How long does it take for this battery to lose 100 J of chemical energy? *Please write clearly. Has to be legible to demonstrate to peers.
Please answer all 9. An electron is in an electric field surrounding a positive charge. It sits at an equipotential line of 20 V. What happens when it moves to another equipotential line of 40 V if the two lines are 0.5 m apart? ) (A) It takes 1.6x 10-19 J to move from 20 V to 40 V (B) The electron does 1.6 × 10-18 J of work moving from 20 V to 40 V. (C) The electron does...
A charge travels from the positive terminal of a 6�-V battery, through a light bulb, and through the battery back to the positive terminal. The total change in voltage experienced by the charge during this journey is A) -1V B)1V C)-6V D)6V E)0V
n is in an electric field surrounding a positive charge. It sits at in 9. An electron ipotential line of 20 V. What happens when it of 40 V if the two lines are 0.5 m apart? moves e eential line an takes 1.6% 10-v J to move from 20 V to 40 V. does 1.6 x 10-8 J of work moving from 20 V to 40 V does 3.2 x 10-18 J of work moving from 20 V to...
