For this case we have that a paper clip is a very small object, to be taken in the hand we feel that its mass is very small, almost imperceptible.
For this reason we can discard option D and option A.
Being so small we can use the milligrams to measure its mass, it is the smallest scale.
Answer:
Option B
Hmmm... I’d say that’s pretty accurate. Good job! Well wishes on whatever it is you’re doing.
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
