If a drop is to be deflected a distance d = 0.330 mm by the time it reaches the end of the deflection plate, what magnitude of charge q must be given to the drop? assume that the density of the ink drop is 1000 kg/m3 , and ignore the effects of gravity.

Modify the equation fδt=δ (mv) to find the force of friction.

A30 kg weight lies on top of a massless piston of area a = 0.01 m2 the exterior air is at a (constant) p =1 atm and t = 27 c. the interior gas is 0.4 moles of (ideal) n2 and it has initial temperature 27.00 degrees c. 1. what is the initial pressure in the interior? a. 29.4 kpa b. 130.7 kpa c. 101.3 kpa the next three questions concern what happens when an amount of heat q is slowly added to the interior, raising the piston by 1 mm and raising the interior temperature to 27.40 c

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative
