Clearly it’s hard to visually identify a critically damped circuit. in lab you distinguished between underdamped and critically damped with the presence of oscillations, but you identified oscillations by eye. given a set of ( x, y ) data points (not a function) how can you mathematically detect oscillations? hint: consider the second derivative

c) up is the direction the magnetic force is acting on the charge.

it would be c. predictability

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
