Answer:
Explanation:
Un electrón tiene una carga negativa de y la masa total es igual al producto del número de electrones y esa carga unitaria. El número de electrones se obtiene al dividir la carga total por la carga unitaria. (An electron has a negative charge of and the total mass is equal to the product of the qunatity of electrons and such unit charge. The quantity of electrons is found by diving the total charge by the unit charge):
Answer:
(a) μ = 0.015kg/m
(b) v = 90.64m/s
Explanation:
(a) The linear density of the string is given by the following relation:
(1)
m: mass of the string = 25.3g = 25.3*10-3 kg
L: length of the string = 1.62m
The linear density of the string is 0.015kg/m
(b) The velocity of the string for the fundamental frequency is:
(2)
f1: fundamental frequency = 41.2 Hz
vs: speed of the wave
l: distance between the fixed extremes of the string = 1.10m
You solve for v in the equation (2) and replace the values of the other parameters:
The speed of the wave for the fundamental frequency is 90.64m/s
