Consider a modified falling cylinder viscometer where the outer tube is open at both ends and immersed within a large body of the same fluid. Since the bottom is open, the displaced fluid does not have to move counter to the falling cylinder, and there is no pressure other than hydrostatic. Obtain an equation for the viscosity of the fluid.

The coefficient of friction is a number that represents the resistance to sliding between two in contact with one another.

Acharge q experiences no net force at a particular point in space. which of the following situations described below must always be true? -there are no other charges nearby. -if there are other charges nearby, they must all have the same sign as q. -if there are other charges nearby, they must all have the opposite sign of q. -if there are other charges nearby, the total positive charge must equal the total negative charge. -none of the above
