Atemperature-stable resistor is made by connecting a resistor made of silicon in series with one made of iron. if the required total resistance is 1300 capital omega in a wide temperature range around 20degrees celsius, what should be the resistances of the two resistors? the temperature coefficients of the resistivities for iron and silicon are: alphairon = 5.0times 10-3 k-1

He viscosities of several liquids are being compared. all the liquids are poured down a slope with equal path lengths. the liquid with the highest viscosity will

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?
