Given that the electric potential is 7.3×10−2 V higher outside the cell than inside the cell, and that the cell membrane is 0.10 μm thick, calculate the work that must be done (in joules) to move one sodium ion from inside the cell to outside.

When a resistor with resistance r is connected to a 1.50-v flashlight battery, the resistor consumes 0.0625 w of electrical power. (throughout, assume that each battery has negligible internal resistance.) what power does the resistor consume if it is connected to a 12.6-v car battery? assume that r remains constant when the power consumption changes.

Edward tolman explained the results of his study by theorizing that the rats were learning about the maze during every trial but they a. were agitated because other groups were getting reinforcement b. could not remember how to demonstrate it without reinforcement c. were not motivated to demonstrate it without reinforcement d. seemed to be too lazy to actually work without reinforcement

Which is not true about oxygen-17 and oxygen-18?
