A sound wave is traveling at 331 m/s and has a frequency of 126 Hz. What is the wavelength?​
damaskus [11]
<h2>Answer</h2>

2.626984127 m

<h2>Explanation:</h2><h2></h2>

You have to know the equation that relates wavelength, frequency, and velocity (it's like speed but a bit different).

v = f x λ

where:

v = velocity

f = frequency

λ = Wavelength

Rearrange to make λ subject:

λ = v / f

We've been given 331 as the speed, 126 as the frequency. Sub it into the equation:

331 / 126 = 2.626984127 m

What size pipette accurately measures 0.8 ml of fluid? indicate the volume and accuracy of the pipette.
chubhunter [2.5K]

The pipette that accurately measures 0.8mL of fluid is P1000 micropipette.

It is given that:-

The volume of fluid = 0.8mL

We know that,

1 mL = 1000 microliter.

Hence,

0.8 mL = 0.8*1000 microliter = 800 microliter

We know that, a P1000 micropipette's volume ranges between 200 microliter to 1000 micro liter.

As,

200 < 800 < 100

Hence, P1000 micropipette is the right instrument.

The accuracy of this pipette decreases as volume decreases. Since the value 800 is near the maximum volume 1000 of the pipette, the accuracy of the pipette will be within a few percentages of the actual value.
