What is the frequency of light that has a wavelength of 310 nm?.
The frequency of a light wave with a wavelength of 310nm will be 9.68 × 10¹⁴ Hz.
What is wavelength?The distance that separates two successive crests or troughs of a wave is defined as its wavelength. It is measured in the wave's direction.
The wavelength of light is characterized as "the distance between the light wave's two successive crests or troughs." The Greek letter lambda represents it.
The frequency of a particle can be calculated by dividing its speed of light by its wavelength, as shown below:
[tex]\lambda=\frac{v}{f}[/tex]
Here, given that,
V = speed of light (3 × 10⁸m/s)
Wavelength = 310nm.
So,
[tex]f = \frac{V}{\lambda}[/tex]
[tex]f=\frac{3*10^8}{310*10^-^9}[/tex]
[tex]f=9.68*10^1^4[/tex]
Thus, 9.68 × 10¹⁴ Hz is the frequency of light that has a wavelength of 310 nm.

Which observation is inconsistent with the ideal gas law.
The observation that is inconsistent with the ideal gas equation is; "When temperature is held constant and volume increases, the pressure increases."
Boyle's law describes the relationship between the pressure and volume of ideal gas. Boyle's law states that, the volume of a given mass of gas is inversely proportional to its pressure at constant temperature.
Hence, the statement that "When temperature is held constant and volume increases, the pressure increases." does not agree with Boyle's law therefore it is inconsistent with the ideal gas law.

Triangle ABC is rotated 45° about point X, resulting in triangle EFD. Triangle A B C is rotated 45 degrees about point X to form triangle E F D. The lengths of sides A C and D E are congruent, the lengths of sides A B and E F are congruent, and the lengths of sides D F and C B are congruent. If EF = 4. 2 cm, DF = 3. 6 cm, and DE = 4. 5 cm, what is CB? 3. 3 cm 3. 6 cm 4. 2 cm 4. 5 cm.
Answer:
3.6 cm
Explanation:
Here, triangle ABC is rotated about point X which results in triangle EFD. Since triangle ABC is rotated it retains its shape and dimensions. This means that triangle ABC is parallel to triangle EFD ie, ABC≈EFD, also both dimensions will be congruent.
Thus
AB = EF
BC = FD
AC = ED
CB = DF
BA = FE
CA = DE
Since length of side DF = length of side CB, and DF = 3.6 cm. Therefore, CB = DF = 3.6 cm
Length of CB = 3.6 cm

How much naalo2 is required to produce 1. 00 kg of na3alf6? 6hf(g) + 3 naalo2(s) --> na3alf6(s) + 3h2o(l) + al2o3(s).
Considering the reaction stoichiometry,1171.43 grams of NaAlO₂ is required to produce 1.00 kg of Na₃AlF₆.
The balanced reaction is:
6 HF + 3 NaAlO₂ → Na₃AlF₆ + 3 H₂O + Al₂O₃
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
HF: 6 moles NaAlO₂: 3 moles Na₃AlF₆: 1 mole H₂O: 3 molesAl₂O₃: 1 moleThe molar mass of each compound is:
HF: 20 g/mole NaAlO₂: 82 g/mole Na₃AlF₆: 210 g/mole H₂O: 18 g/moleAl₂O₃: 102 g/moleSo, by reaction stoichiometry, the following amounts of mass of each compound participate in the reaction:
HF: 6 moles× 20 g/mole= 120 grams NaAlO₂: 3 moles× 82 g/mole= 246 grams Na₃AlF₆: 1 mole× 210 g/mole= 210 grams H₂O: 3 moles× 18 g/mole= 54 gramsAl₂O₃: 1 mole× 102 g/mole= 102 gramsThen you can apply the following rule of three: if by stoichiometry 210 grams of Na₃AlF₆ are produced by 246 grams of NaAlO₂, 1000 g (1kg) of Na₃AlF₆ are produced by how much mass of NaAlO₂?
[tex]mass of NaAlO_{2} =\frac{1000 grams of Na_{3} AlF_{6} x246 grams of NaAlO_{2}}{210 grams of Na_{3} AlF_{6}}[/tex]
mass of NaAlO₂= 1171.43 grams
Finally, 1171.43 grams of NaAlO₂ is required to produce 1.00 kg of Na₃AlF₆.

If you have a fixed-rate mortgage, the state of the economy won't have an effect on it because the interest rate is fixed. On the other hand, an adjustable-rate mortgage will be significantly impacted by the economy, which could result in a significant payment shock if the rate rises.
What would pay in total using the fixed-rate mortgage?A fixed-rate mortgage is a type of house loan that has an agreed-upon interest rate for the entire term of the loan.
The borrower will keep on making the same monthly principal and interest payments, and the interest rate on the mortgage will essentially not change for the life of the loan.
The loan amount is multiplied by the interest rate to determine the interest on fixed-rate mortgages. The mortgage interest can be divided into yearly and monthly payments.
Therefore, First, convert the interest rate to decimal form. The mortgage loan amount is then multiplied by the decimal for the annual interest.
