The evaporation of liquid water from the surface of Earth is an important step in the water cycle. How do water molecules obtain
Alex777 [14]
<span>Well, during the day, the water, as well as the surfaces surrounding the water, are heated by various thermodynamic processes: conduction, convection, radiation, etc. This in turn warms the water molecules in the lakes, streams, rivers, and oceans, thereby transferring heat (their kinetic energy) to the water molecules, which in turn receive that energy from the surrounding surfaces, or directly via radiation/insolation from the sun. When the water molecules attain enough energy, some of them attain enough energy to escape the surface of the liquid and enter the gas phase. Hence, as water is heated, more and more water molecules attain enough kinetic energy to enter the gas phase.</span>

she will have to listen to all of carefully while she is writing for example:

she will listen and look at her writing page (where she writes) she looks while she listens and writes what she hears for example again:

(pretend as i am her.)

"Hey mom, dad, brother come i see crabs!" as she writes it she focuses on how she writes and stops the video and back up again to listen so she can see if it was correct.

X^2+13x+30<br> How do I factor this?<br> will give brainiest
podryga [215]

Answer:

(x+10) (x+3)

Explanation:

1) this quadratic equation is in the form of: ax^2+bx+c

where we need to figure out what*what=c(30)

and what+what=13(b)

factors of 30:  -1,-30  1,30  2,15  -2,-15  3,10  -3,-10  5,6   -5,-6

factors of 30 which equal 13:    3,10

lets substitute 3 and 10 in lace of 13x to factor by grouping:

x^2+3x+10x+30

make two sets:

set a) x^2+3x

set b) 10x+30

the GCF in set a is "x":

x(x+3)

The Gcf in set b is 10:

10(x+3)

now combine the terms outside the parantheses:

(x+10)(x+3)=0

Hope this helps!

If you hit the surface of Iron with a photon of energy and find that the ejected electron has a wavelength of .75 nm, what is th
lubasha [3.4K]

Answer:

The wavelength of the incoming photon is 172.8 nm

Explanation:

The wavelength of the incoming photon can be calculated with the photoelectric equation:

KE = h\frac{c}{\lambda_{p}} - \phi   (1)

Where:

KE: is the kinetic energy of the electron

h: is Planck's constant = 6.62x10⁻³⁴ J.s  

c: is the speed of light = 3.00x10⁸ m/s

\lambda_{p}: is the wavelength of the photon =?  

Φ: is the work function of the surface (Iron) = 4.5 eV        

The kinetic energy of the electron is given by:

KE = \frac{p^{2}}{2m} = \frac{(\frac{h}{\lambda_{e}})^{2}}{2m}  (2)

Where:  

p: is the linear momentum = h/λ

m: is the electron's mass = 9.1x10⁻³¹ kg

\lambda_{e}: is the wavelength of the electron = 0.75 nm = 0.75x10⁻⁹ m

Hence, the wavelength of the photon is:

\frac{(\frac{h}{\lambda_{e}})^{2}}{2m} = h\frac{c}{\lambda_{p}} - \phi

\lambda_{p} = \frac{hc}{\frac{h^{2}}{2m\lambda_{e}^{2}} + \phi} = \frac{6.62 \cdot 10^{-34} J.s*3.00\cdot 10^{8} m/s}{\frac{(6.62 \cdot 10^{-34} J.s)^{2}}{2*9.1 \cdot 10^{-31} kg*(0.75 \cdot 10^{-9} m)^{2}} + 4.5 eV*\frac{1.602 \cdot 10^{-19} J}{1 eV}} = 1.728 \cdot 10^{-7} m = 172.8 nm      

Therefore, the wavelength of the incoming photon is 172.8 nm.

I hope it helps you!

In table below, there are descriptions of an experiment on samples of three different chemical compounds. Decide whether the com
Ulleksa [173]

Answer:

1. molecular

2. molecular

3. molecular

Explanation:

Molecular compounds typically exhibit covalent compound characteristics. They are pure substances formed when atoms are linked together by sharing electrons while ionic compounds are formed due to the transfer of electrons. Molecular substances tend to melt at moderately warm temperatures (i.e. 50° C) and it is overlapping as seen in compound 1, which makes it to be molecular in nature.

Molecular compounds are not affected by conductivity, hence they are electrically neutral.

Molecular compounds have a strong smell and have freezing and boiling point at accessible temperatures. A clear liquid at room temperature which has a fruity strong smell can be an organic compound. These organic compounds made up of covalent bonds and are molecular in nature.
