Thor is battling the Frost Giants and he uses his hammer, Mjolnir, to zap them with lightning. Thor unleashes a bolt toward the nearest Giant. Mjolnir has an electric potential of zero and the Frost Giant has an electric potential of either +1.9 × 108 V or -1.9 × 108 V (you will decide during part 1 of the question). In order for electricity to conduct through dry air, the electric field between Thor and the Frost Giant must have a magnitude of 3.2 x 106 V m A negatively charged hydroxide ion (OH¯) in the lightning bolt travels away from Thor. OH ions hold a charge of -1.6 × 10-¹⁹ C and they have a mass of 2.82 × 10-26 kg. The OH- ion speeds up from rest to a velocity of 6.3 × 105 m.

its a physics hangman game, whats the 7 letter word that describes this statement in the picture.

Two metal plates are charged such that there is a 10 V potential difference between them.  A positive charge is to be moved from the lower plate to the top plate. Starting from the point on the lower plate, following which path to the top plate will we do the least work moving the charge?

Two plates separated by a distance d = 15.3 mm are charged to a potential difference V = 7.25 V. A constant force F = 8.31 N pushes a –8.30 mC charge from the positively charged plate to the negatively charged plate. Calculate the change in the kinetic energy AK, potential energy AU, and total energy AE of the charge as it travels from one plate to the other. Assume the initial speed of the charge is 0. AK = AU =

An object with charge q= −4.00×10−9 C is placed in a region of uniform electric field and is released from rest at point A. After the charge has moved to point B, 0.500 m to the right, it has kinetic energy 5.00×10−7 J. Express your answer with the appropriate units. Part A:If the electric potential at point A is +30.0 V, what is the electric potential at point B? VB=__ Part B:What is the magnitude of the electric field? E=__

You are working in a laboratory, using very sensitive measurement equipment. Your supervisor has explained that the equipment is also very sensitive to electrical discharge from human operators. Specification tables for the equipment indicate that an electrical discharge providing even a very small amount of energy of 250 μJ is enough to damage the equipment. Your supervisor wants to install an apparatus that will be used to remove the electrical charge from individuals’ bodies before they touch the equipment. To do this, she asks you to estimate (a) the capacitance of the human body and determine (b) the charge on the body and (c) the electric potential of the body, relative to a point infinitely far away, corresponding to the energy transfer that will damage the equipment.

A moving particle encounters an external electric field that decreases its kinetic energy from 9930 eV to 8130 eV as the particle moves from position A to position B. The electric potential at A is -59.0 V, and that at B is +13.0 V. Determine the charge of the particle. Include the algebraic sign (+ or -) with your answer.

A potential difference of 75 mV exists between the inner and outer surfaces of a cell membrane. The inner surface is negative relative to the outer surface. How much work is required to eject a positive sodium ion (Na+) from the interior of the cell?
