If the volume of one drop is 0.031 mL according to Stu Dent’s measurement, approximately what volume would 22 drops be? Answer w

olasank [31]

Answer:

Volume of 22 drop will be 0.68 ml

Explanation:

We have given volume of one drop = 0.031 ml

We know that 1 liter = 1000 ml

So $1ml=10^{-3}L$

So 0.031 ml will be equal to $0.031\times 10^{-3}L$

We have to find the volume of 22 drop

For finding volume of 22 drop we have to multiply volume of one drop by 22

So volume of 22 drop will be $=22\times 0.031\times 10^{-3}=0.682\times 10^{-3}L=0.68mL$

So volume of 22 drop will be 0.68 ml

If a plane has an airspeed of 40 m/s and is experiencing a crosswind of 30 m/s, what is its ground speed in m/s?

Anon25 [30]

<h2>Answer:50 $ms^{-1}$ </h2>

Explanation:

Let $v_{a}$ be the airspeed.

Let $v_{w}$ be the cross wind speed.

We know that,ground speed is the vector sum of airspeed and cross wind speed and airspeed is perpendicular to cross wind speed.

If $v_{1}$ and $v_{2}$ are two perpendicular vectors,the resultant vector has the magnitude $\sqrt{|v|_{1}^{2}+|v|_{2}^{2}}$

Given,

$v_{a}=40ms^{-1}\\v_{c}=30ms^{-1}$

So,the ground speed is $\sqrt{40^{2}+30^{2}}=\sqrt{2500}=50ms^{-1}$

What would the density of an object be with a mass of 0.8g

True [87]

The density of the object is 0.032 g/cm^3.

<h3>What is density?</h3>

The term density means the ratio of the mass to the volume of an object. Now we know that when an object is dense that it would sink to the bottom of a fluid.

Now given that;

Mass = 0.8 g

volume= 25 cm^3

Density = mass/volume

Density = 0.8 g / 25 cm^3

= 0.032 g/cm^3

The cutoff frequency for a certain element is 1.22 x 10^15 Hz. What is its work function in eV?

Dovator [93]

The work function in eV for the given cutoff frequency is 5.05 eV.

<h3>What is cutoff frequency?</h3>

The work function is related to the frequency as

Wo = h x fo

where, fo = cutoff frequency and h is the Planck's constant

Given is the cutoff frequency for a certain element is 1.22 x 10¹⁵ Hz

Wo = 6.626 x 10⁻³⁴ x 1.22 x 10¹⁵ Hz / 1.6 x 10⁻¹⁹

Wo = 5.05 eV

Thus, the work function is 5.05 eV

when you make an inference what needs to be in the text in the order for you to be able to accomplish this

cluponka [151]

Answer:

To make an inference what needs to be in the text in the order for you is explained below in complete details.

Explanation:

Making an inference requires using what you recognize to guess what you don't understand or understanding between the series. Scholars who make inferences use the evidence in the text along with their own practices to encourage them to figure out what is not straight said, making the text special and remarkable.
