A uniform thin rod of mass =3.41 kgM=3.41 kg pivots about an axis through its center and perpendicular to its length. Two small bodies, each of mass m=0.249 kgm=0.249 kg , are attached to the ends of the rod. What must the length LL of the rod be so that the moment of inertia of the three-body system with respect to the described axis is =0.929 kg·m2I=0.929 kg·m2

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
