2) The density of a string was increased by a factor of two. How will the...
If the surface area of a cube is increased by a factor of 2 (so that the new surface area is twice the size of the original surface area), by what factor does the volume of the cube change?
This question has multiple parts Question 8 Two waves with identical frequency f and amplitude A are superimposed on each other. The waves are partially out of phase (one is shifted by 1/4 wavelength compared to the other). The resultant wave will have: Select the correct answer O Frequency less than f, amplitude equal to 2A O Amplitude exacly equal to 0 O Frequency equal to f,amplitude less than 2A O Frequency equal to f, amplitude equal to 2A Frequency...
A guitar string has been plucked so it vibrates with the longest wavelength possible (fundamental). Now you hold the string down 1/2 of the way in from one end so it can't move there. If you pluck the string now, how does the new longest wavelength possible compare to the original one? Anew-Aold Anew Aold /4
1) Does the quality factor depend on the frequency of the original AC signal? 2) How can the quality factor of the rectifier circuit be increased?
The displacement of a transverse traveling wave on a string under tension is described by: D(x, t) = (2.0 cm) .sin((12.57 rad/m)x + (638 rad/s)t + /2] The linear density of the string is 5.00 g/m. 1. What is the tension in the string? 2. What is the maximal speed of a point on the string? String 2 3. The original string (String 1) is tied to a second string with String 1 a linear density of 12 g/m, as...
The displacement of a transverse traveling wave on a string under tension is described by: D(x, t) = (2.0 cm) sin((12.57 rad/m)x+ (638 rad/s)t + T/2] The linear density of the string is 5.00 g/m. 1.

2. Suppose you have a string with linear mass density 4.5 g/m, with two fixed ends 10 Suppose you have a string with linear mass density 4.5 g apart. What is the velocity of a wave on the string if the tension of the string is supplied by a hanging mass of 275 g? 3. For the previous question, what are the three lowest frequencies that you could observe a standing wave?
a 2.0 m length of string with a mass density of 2.95 x 10^-4 kg/m is fixed at both ends and driven at 120 Hz. The tension is varied to obtain standing waves (resonance) on the string. 1. what is the longest wavelength for a standing wave possible on the string? 2. the tension on the string is varies to obtain fourth harmonic a. what is the wavelength of this standing wave? b. what is the wave speed 3. what...
3. If the amperage in your electrolysis cell were increased by a factor of 2, what effect would this have on the time required to produce the same amount of hydrogen? 4. Electrolysis of an NaCl solution with a current of 2.00 A for a period of 200 s produced 59.6 mL of Cl2 at 650 mm Hg pressure and 27 °C. Calculate the value of the Faraday's Constant from these data. 5. Why are different products obtained when molten...
In Figure (a), string 1 has a linear density of 4.18 g/m, and string 2 has a linear density of 8.95 g/m. They are under tension due to the hanging block of mass M = 543 g. Calculate the wave speed on (a) string 1 and (b) string 2. (Hint: When a string loops halfway around a pulley, it pulls on the pulley with a net force that is twice the tension in the string.) Next the block is divided...
