Answer: their is relationship
Explanation: The amount of light produced at each wavelength depends on the temperature of the object producing the light. Stars hotter than the Sun (over 6,000 degrees C) put out most of their light in the blue and ultraviolet regions of the spectrum.

Further explanationThe mole is the number of particles(molecules, atoms, ions) contained in a substance
1 mol = 6.02.10²³ particles
Can be formulated
N=n x No
N = number of particles
n = mol
No = Avogadro's = 6.02.10²³

Calculate the energy of the lasers in a Blu-ray player, which emit at a wavelength of 4.05x10−7 m.
Answer:
4.907 × 10^-19 J
Explanation:
The energy of the lasers in a Blu-ray player can be calculated by using;
E = hf
Where;
E = Energy of laser (J)
h = Planck's constant (6.626 × 10^-34 J/s)
f = frequency (Hz)
However, the frequency must be known first in order to calculate the energy. The frequency can be calculated using the formula:
f = v/λ
Where:
λ = wavelength (4.05x10−7 m.)
v = speed of light (3 × 10^8m/s)
f = frequency (Hz)
f = 3 × 10^8 ÷ 4.05 x 10^−7
f = 0.7407 × 10^(8 + 7)
f = 0.7407 × 10^15
f = 7.407 × 10^14 Hz
Using E = hf
E = 6.626 × 10^-34 × 7.407 × 10^14
E = 49.07 × 10^(-34 + 14)
E = 49.07 × 10^-20
E = 4.907 × 10^-19 J

How would frictional force be affected in space?
Answer:
when two surfaces rub together in outer space, there will be friction. Friction is a surface effect and doesn't depend upon there being air. There is also a force like air resistance from the very sparse gas in space, but it will be very, very small, since space is a very good vacuum.

In the reaction below, how would adding more of reactant A affect the equilibrium of the system? (2 points)
A + B ⇄ C + D
a
Shift it to the right toward the products.
b
Shift it to the left toward the reactants.
c
Equally create more products and reactants.
d
It would have no effect.
Answer:
a . Shift it to the right toward the products.
Explanation:
In the reaction, if more of the reactant A is added to the system, the reaction will shift towards the products.
If a system at equilibrium is disturbed by changing the concentration of one of the substances, all the concentration will change until a new equilibrium point is reached. If we add more reactants, the concentration is increased and the reaction shifts to the right so as to maintain the constancy of the equilibrium constant.Answer: a . Shift it to the right toward the products.

Why is the supply of oil in Texas decreased from its supply fifty years ago? A. Oil is a nonrenewable resource B. Oil is a renewable resource C. Oil takes sixty years to replenish itself. D. Oil wells are no longer being dug.
Answer:
A
Explanation:
The supply of oil in Texas decreased from its supply fifty years ago because oil is a nonrenewable resource.
A nonrenewable resource is one that cannot be replenished naturally at the same pace as its usage and hence, decreases and eventually gets exhausted with usage or exploitation over time. This is unlike renewable energy resource that gets replenished even with usage.
The more the oil in Texas is exploited, the more its supply or reserve will decrease. This is why the supply of oil has decreased from what it is fifty years ago.
The correct option is A.
The diagram shows a certain kind of cell with all of its major parts labeled.
Which statement is supported by the diagram?
The cell must be eukaryotic because it has a cell membrane and a cell wall.
The cell must be prokaryotic because it has a cell membrane and a cell wall.
The cell is eukaryotic because it does not have any membrane-bound organelles.
The cell is prokaryotic because it does not have any membrane-bound organelles.
Answer:
I think it's the last one
D. The cell is prokaryotic because it does not have any membrane-bound organelles.
Explanation:
The difference between eukaryotic and prokaryotic cells are that the eukaryotic cells have a nucleus and they have membrane-bound organelles, and prokaryotic cells don't.

For visible light, explain how wavelength and energy vary for the different colors. Provide the trends in wavelength for the spectrum of light (purple to blue to green to yellow to orange to red). How is this different for energy?
Answer:
See explanation
Explanation:
If you look closely at the image attached, you will discover that the order of increasing wavelength in the visible spectrum is;
violet < indigo< blue < green < yellow < orange < red
On the order hand, the energy of the photons increases in the order;
Red < orange < yellow < green < blue < indigo < violet
Since energy follows a trend opposite to that of wavelength, we can see that the greater the wavelength of light, the lower the energy of photon corresponding to that particular colour.

3.00 Liters of gas are stored at standard temperature and pressure. If the volume of the gas is increased to 4.00 L at a constant temperature what is the new pressure of the gas
The new pressure of the gas : 0.75 atm
Further explanationBoyle's Law
At a constant temperature, the gas volume is inversely proportional to the pressure applied
[tex]\rm p_1V_1=p_2.V_2\\\\\dfrac{p_1}{p_2}=\dfrac{V_2}{V_1}[/tex]
P₁=1 atm ⇒ standart temperature and pressure (STP)
V₁=3 L
V₂=4 L
[tex]\tt P_2=\dfrac{P_1.V_1}{V_2}\\\\P_2=\dfrac{1\times 3}{4}\\\\P_2=0.75~atm[/tex]
