+One clue used by your brain to determine the direction of a source of sound is the time delay $\Delta t$ between the arrival of the sound at the ear closer to the source and the arrival at the farther ear. Assume that the source is distant so that a wavefront from it is approximately planar when it reaches you, and let $D$ represent the separation between your ears. Based on the time-delay clue, your brain interprets the submerged sound to arrive at an angle $\theta$ from the forward direction. Evaluate $\theta$ for fresh water at $20^\circ$C.

A potential difference $\Delta$ across the electrodes deflects the proton so that it strikes the outer end of the lower electrode.

What magnetic field strength will allow the proton to pass through undeflected while the $500$ $V$ potential difference is applied?
