Assuming you are talking about the atomic mass of magnesium chloride
M = n/V
M = 1/3.77
M = .265
Answer:
1.5×10⁷ Hz
Explanation:
From the question given above, the following data were obtained:
Wavelength of radio wave (λ) = 20 m
Frequency (f) =?
Frequency and wavelength of a wave are related by the following equation:
v = λf
Where:
'v' is the velocity of electromagnetic wave.
'λ' is the wavelength
'f' is the frequency.
With the above formula, we can obtain the frequency of the radio wave as illustrated below:
Wavelength of radio wave (λ) = 20 m
Velocity (v) = 3×10⁸ m/s
Frequency (f) =?
v = λf
3×10⁸ = 20 × f
Divide both side by 20
f = 3×10⁸ / 20
f = 1.5×10⁷ Hz
Thus the frequency of the radio wave is 1.5×10⁷ Hz
Answer:
Explanation:
Reflection of trees in clear water and reflection of mountains in a lake. Wings of most butterflies are identical on the left and right sides. Some human faces are the same on the left and right side. People can also have a symmetrical mustache.
Weathering steel or another name for it is cortensteel.
180 K
V1/T1 = V2/T2
V1 = 500 mL
T1 = 300 K
V2 = 300 mL
Solve the equation for T2 —> T2 = V2T1/V1
T2 = (300 mL)(300 K) / (500 mL) = 180 K
