How is it possible for a bound nucleus to have less mass than its constituent parts?

What distance does a car travel as its speed changes from 0 to 20 m/s in 17 s at constant acceleration?

The space between two 15-in.-long concentric cylinders is filled with glycerin (viscosity = 8.5 × 10-3 lb·s/ft2). the inner cylinder has a radius of 1 in. and the gap width between cylinders is 0.1 in. determine (a) the torque and (b) the power required to rotate the inner cylinder at 180 rev/min. the outer cylinder is fixed. assume the velocity distribution in the gap to be linear.

Me with this and you will be marked brainliest
