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 series RC circuit, which is made from a battery, a switch, a resistor, and a 4.0-µF capacitor, has a time constant of 8.0 ms. what is the resulting time constant
a stone is projected at a cliff of height h with an initial speed of 49.0 m/s directed at an angle ?0 = 63.0° above the horizontal. The stone strikes at A, calculate the speed of the stone just before impact
Physics: Mechanics about two curling stones - calculate speed, resistive force Two curling stones A and B, each having a mass of 2 kg, are on an ice rink floor. A is stationary and 10 meters from a boundary wall, while B is sliding at right angles..
