Which of the following choices concerning the net magnetic flux through any enclosed surface is true according to gauss' law for magnetic fields? select one: a. the net magnetic flux in this case would be a vector quantity equal to the enclosed magnetic field. b. the net magnetic flux in this case would be a positive scalar quantity c. the net magnetic flux in this case would be a vector quantity equal to the number of magnetic monopoles passing through the surface per unit time. d. the net magnetic flux in this case would be a negative scalar quantity. e. the net magnetic flux in this case would be equal to zero.

Is there a point between a 10 nc charge and a 20 nc charge at which the electric field is zero?

Simon is writing a story about an astronaut whose spacecraft has been boarded by space pirates. the astronaut has her lucky penny in her hand behind her back as the space pirates break into the control room. she has just locked the controls so that the ship is accelerating in the direction of the control room’s ceiling. simon wants the astronaut to use the penny to hit a button on the control panel to turn off the lights and escape. the button is located a short distance behind and below the astronaut’s hands. how should simon use the theory of relativity to describe what the astronaut must do in order to hit the button?
