How to do the equation p1v1 = p2v2 as an equation layed out like:

1 answer:

4 0

P1 and P2 are the pressures, and V1 and V2 are the volumes. So you take the first pressure and volume you are given and place them into the equation P1V1 so the first part of the equation would be 101000*0.5 = P2V2. You then rearrange the equation to find what you want, in this instance you would do 50500/0.25 = P2... therefore P2 = 2020000Pa or 2.02*10^6Pa

You're collecting data in BeyondLabz for an object in free fall, subject to air resistance. How do you know when you've collecte

Enough data points would have been collected when specific data for upward and downward motion are collected.

<h3>What is a Data point?</h3>

A data point is a discrete unit of information. This information is always unique.

An object subjected to free fall is under the influence of gravity. An object subjected has different time of motion for upward and downward motion.

Thus, we can conclude that enough data points would have been collected when specific data for upward and downward motion are collected.

You're using a monochromatic beam of light with wavelength 500 nm in an interferometer. What is the minimum distance you would n

xxTIMURxx [149]

Answer:

The minimum distance moved by mirror is 125 nm

Explanation:

Given:

Wavelength of light $\lambda = 500 \times 10^{-9}$ m

Here given in question, spot of constructive interference change to a destructive interference.

Hence minimum distance moved by one of mirror is given by,

$t = \frac{1}{2}(\frac{\lambda}{2} )$

Where $t =$ distance moved by mirror

$t = \frac{\lambda }{4}$

$t = \frac{500\times 10^{-9} }{4}$

$t = 125 \times 10 ^{-9}$

Therefore, the minimum distance moved by mirror is 125 nm

Ask Your Teacher A beam of light is incident from air on the surface of a liquid. If the angle of incidence is 33.5° and the ang

Oduvanchick [21]

Answer:

The critical angle for the liquid when surrounded by air is 30 degrees.

Explanation:

Given that,

The angle of incidence is 33.5° and the angle of refraction is 19.3°. Firstly, we can find the refractive index of the liquid. It can be calculated using Snell's law as :

$n=\dfrac{\sin i}{\sin r}\\\\n=\dfrac{\sin (33.5)}{\sin (19.3)}\\\\n=2$

The critical angle is given by :

$\theta_c=\sin^{-1}(\dfrac{n_1}{n_2})$

Here, $n_1$ is refractive index of air and $n_2$ is refractive index of liquid.

$\theta_c=\sin^{-1}(\dfrac{1}{2})\\\\\theta_c=30^{\circ}$

So, the critical angle for the liquid when surrounded by air is 30 degrees.
