Answer:
Explanation:
Electrons have negative charge and they orbit around the nucleus.
Protons have positive charge and are inside the nucleus
Neutrons have neutral charge they are also inside the nucleus
the nucleus is the middle of the atom
the electron cloud is a cloud which the electrons travel around
Answer:- Frequency is 
.
Solution:- frequency and wavelength are inversely proportional to each other and the equation used is:
where, 
is frequency, c is speed of light and 
is the wavelength.
Speed of light is 
.
We need to convert the wavelength from nm to m.
( 
)
= 
Now, let's plug in the values in the equation to calculate the frequency:
= 
or
since, 
So, the frequency of the green light photon is .
I'm assuming false but really have no clue
The required pressure of the gas is 546 mmHg.
<h3>What is the relation between volume and pressure?</h3>
Relation between the volume and pressure of gas is explained through the ideal gas equation PV = nRT, and for the question required equation is:
P₁V₁ = P₂V₂, where
P₁ & V₁ are the initial pressure and volume.
P₂ & V₂ are the final pressure and volume.
On putting values from the question to the equation, we get
P₂ = (780)(350) / (500) =
P₂ = 546 mmHg
Hence required pressure is 546 mmHg.

<h3>Solution:</h3>
f(x) = 3x - 1 = 0
f(x) = x = 1/3
By putting the value of x in g(x), we get
g(x) = 2(1/3)^2 - 3
g(x) = 2(1/9) - 3
g(x) = 2/9 - 3
g(x) = -25/9
<h2>Answer:</h2>
g(x) = -25/9
