To calculate:The frequency of the tuning fork.

Answer to Problem 56A
The frequency of the tuning fork is
Explanation of Solution
Given info:
A tuning fork vibrates over the mouth of a vertical tube filled with water.
First resonance length (
Second resonance length (
Formula used:
The distance between water levels is equal to the distance between two successive nodes of half of a wavelength.
In addition, the frequency is given by
Calculation:
As per the problem
First resonance length (
Second resonance length (
Wavelength of the resonant sound
Calculate frequency using the wavelength calculated above and take speed of sound in air
Conclusion:
Thus, thefrequency of the tuning fork is

- Example Two charges, one with +10 μC of charge, and another with - 7.0 μC of charge are placed in line with each other and held at a fixed distance of 0.45 m. Where can you put a 3rd charge of +5 μC, so that the net force on the 3rd charge is zero?arrow_forward* Coulomb's Law Example Three charges are positioned as seen below. Charge 1 is +2.0 μC and charge 2 is +8.0μC, and charge 3 is - 6.0MC. What is the magnitude and the direction of the force on charge 2 due to charges 1 and 3? 93 kq92 F == 2 r13 = 0.090m 91 r12 = 0.12m 92 Coulomb's Constant: k = 8.99x10+9 Nm²/C² ✓arrow_forwardMake sure to draw a Free Body Diagram as wellarrow_forward
