A tuning fork with a frequency if 536 Hz is placed near the top of a tube opened at one end and closed at the other end. The water level is lowered so that the length of the air column slowly increases from an initial value of 20.25cm. Determine the next two values that correspond to resonance modes
A spaceship is observed by a stationary observer to be moving at .6 c. How fast does the laser beam travel relative to the observer
Positive point-charges of +36.0 mC (Micro C) are fixed at two of the vertices of an equilateral triangle with sides of 3.30 m, located in vacuum. Determine the magnitude of the E-field at the third vertex
