The method that would produce the same charge is conduction only.
Answer: v= 330m/s
Explanation: the length (l) of an open closed pipe is related to the wavelength (λ) as shown in the formulae below
l = λ/4
where l = 0.55m, hence we have that
0.55 = λ/4
λ = 0.55*4
λ = 2.2m
from the question, it can be seen that the fundamental frequency is 150Hz.
Recall that we have v=fλ, where v = speed of wave, f= frequency, λ= wavelength
v =2.2 * 150
v = 330 m/s
IV - Temperature
DV - Light intensity
Depends, typically very expensive
The spring constant is the number of Newtons needed to cause an extension of 1metre. So in this case it is 15/0.3 = 50 N/m
