I think the answer would be Switch 1 open; switches 2, 3, and 4 closed. It is letter D. This will happen when there is a low resistance and a high circuit so from the choices above, when two bulbs are open and one bulb is close, so there is a low resistance and high voltage.
Resistivity of nichrome is high.
Answer: 183.8Hz
Explanation:
Given that,
wavelength of sound (λ) = 1.85 m
frequency of the sound (F) = ?
Recall that the speed of sound (V) in air is a constant with a value of 340m/s
So, apply the formula
V = F λ
340 m/s = F x 1.85 m
F = 340m/s / 1.85m
F = 183.8Hz
Thus, the frequency of the sound that is
generated is 183.8 hertz
