Upon what properties of the sound wave do the (a) loudness, (b) pitch and (c) quality of a musical note depend? why do the string on a quitar have diffrent pitches( frequency) even though they are same length? if the string were only 1/2 as dense as you found it to be how would the tension have to change in each case to produce the same number of segments (same wavelength)?
it is found experimentally that the electric field in a certain region of earths atmosphere is directed vertically
Two slits with a separation of 8.5 x 10^(-5) m create an interference pattern on a screen 2.3 m away. find the wavelength of the light used in the experiment
The speed limit for both roads is 35 mi/h, and the driver of the northward-moving vehicle claims he was within the speed limit when the collision occurred.
If the frequency is variable and the length of the closed (at both ends) tube is fixed at 45 cm, sketch the plastic tube showing the position of the nodes and anti-nodes for the three lowest resonant.
Consider NH3 vapor acting as a van der Waals gas with coefficients a = 4.169 atm-L2-mol-2 and b = 0.0371 L-mol-1. How much heat must be added to 50.0 g of the gas so that it experiences no change in internal energy as it undergoes isothermal reversib..
What is the charge-conjugate reaction to K- + p ----> K-0 + n? Can a K-, p system be an eigenstate of the charge conjugation operator?
Two metal spheres of different sizes are charged such that the electric potential is the same at the surface of each. Sphere A has a radius 7 times that of sphere B. Let and be the charges on the two spheres, and let and be the electric-field magnitu..
