Answer:
230hz
Explanation:
Hello,
To solve this question, we gave to use the relationship between velocity-frequency-wavelength to find the frequency in this question.
V = Fλ
V = velocity or speed of the wave
F = frequency of the wave
λ = wavelength of the wave
Data;
V = 414m/s
λ = 1.8m
f = ?
V = fλ
f = v/λ
f = 414/1.8
f = 230hz
The frequency of the wave is 230hz
Answer:
The conversion factor is 14.79 mL/Tbsp.
Explanation:
To do an unity conversiton, we can make a factor by a ratio transformation:
So, the conversion factor is 14.79 mL/Tbsp and 3 Tbsp has 44.37 mL.
Answer: increasing frequency or energy and decreasing wavelength.
Explanation:
Electromagnetic wave is defined as the wave which is associated with both electrical and magnetic component associated with them. They can travel in vacuum as well and travel with the speed of light i.e
The electromagnetic spectra consist of radio waves, microwaves, infrared ,Visible , ultraviolet, X rays and gamma rays arranged in order of increasing frequency or increasing energy and decreasing wavelengths.
The number of grams of Magnesium oxide= 106 g
<h3>Further explanation</h3>
Given
2.63 moles of Magnesium oxide
Required
mass of Magnesium oxide
Solution
The mole is the number of particles contained in a substance
<em>
1 mol = 6.02.10²³
</em>
Moles can also be determined from the amount of substance mass and its molar mass
Mol = mass : Molar mass
Mass of Magnesium oxide(MgO, MW=40.304 g/mol) :
= mol x MW
= 2.63 x 40.304
= 106 g
