A charge of 50 coulombs is moved from point A to point B by expending 350 joules of energy. What is the resulting voltage VBA? Round your answer to two significant figures. VBA Number V

A 1.5 V battery is added to the photoelectric effect apparatus as shown below. Monochromatic light source Evacuated tube + 1.5 V B Make a sketch of the above circuit and label electrodes A and B according to the type of charge (+ or -) that accumulates (whether the light is on or off). When the light is turned on consider the following questions: • Is the number of electrons emitted from electrode Beach second when there is a battery in the circuit greater than, less than. or equal to the number emitted each second when there is no battery? Explain. • What is the potential difference across the electrodes (AV = VA - VB)? • What does your answer to the above question imply about whether the net charge on each of the electrodes changes? Explain. • Write an expression relating the potential difference AV to the change in kinetic energy of a single electron as it moves from electrode B to electrode A. (Hint: Consider the work done by the electric field between the electrodes or the…

Assuming that the diodes in the circuits of Figure-3 are ideal, utilize voltage divider theorem to simplify the circuits and thus find the values of the labeled current and voltage. Note: please solve within 30 minutes. Avoid plagiarism

Calculate the equivalent resistances Rin of the following circuits. (The resistance value of the diodes in the conduction will be 0, the resistance value of the diodes in the insulation will be taken as infinity. R1=10ohm
