Question 13 change in potential mengy of a A uniforn electric field, with a magnitude of $00 N C, is directed parallel to the positive z-aris. If the potestial at x -3.0 m is 1,400 V what s the proton as it moves from x-51n to x = 3 m? (@p=16×10-19C) t a 1 12 × 10-21 J 16x 10-17 e 448 × 10-16 J O b 500J 0d488×10-16J 0
The homework is due after an hour and a half from now if you can
help, please. Thank you!
A rod (length = 10 cm) moves on two horizontal frictionless conducting rails, as shown. The magnetic field in the region is directed perpendicularly to the plane of the rails and is uniform and constant. If a constant force of 0.60 N moves the bar at a constant velocity of 3.2 m/s, what is the current through the 12-2 load resistor?...
1) A proton (q= 1.6 X 10^-19 C) moves along a uniform E-field ( 3.0 v/m) for a distance of 10 cm. what is the change in kinetic energy of the proton? a) 4.0 X 10^-19 J b) 8.6 X 10^-20 J c) 4.8 X 10^-20 J d) 1.6 X 10^-21 J 2) When a charged particle moves from a higher equipotential surface to a lower equipotential surface what is the nature of the work done by the electric field?...
VERSIUN -B- nen a positive charge moves opposite to the direction of the electric field, A) the field does positive work on it and the potential energy increases. B) the field does positive work on it and the potential energy decreases. C) the field does negative work on it and the potential energy increases. Motion D) the field does negative work on it and the potential energy decreases. 2) A strong lightning bort transfers about 40 C to Earth. How...
PLEASE HELP ME AND SHOW STEPS. THANK YOU
1) It is desined to step up a vollage of 120 V to 96,000 v. The turns ratio N/N, of the transformer a) I/28 b) (64 x 10y )28 d) 8001 if the voltage is stepped that power is not lost in an ideal transformer, consider the situation in the above question. 2) Starting from the idea t up 800 times, the current is a) the same, since power is the same...
