Answer:
The correct answer is - Frequency is the number of wavelengths, which is measured in hertz.
Explanation:
Frequency is the number of waves that go through a fixed point at a particular time. Hertz is the SI unit for frequency which means that one hertz is equal to a unit number of waver passes in a unit time to a fixed point.
As the frequency of a wave increases which means the number of waves increases in the unit time, the shorter the wavelength will be.
a higher frequency wave has more energy than a lower frequency wave with the same amplitude.
The mass of nitrogen collected is mathematically given as
M-N2=0.025gram
<h3>What is the mass of nitrogen collected?</h3>
Question Parameters:
A sample weighing 2.000g
the liberated NH3 is caught in 50ml pipeful of H2SO4 (1.000ml = 0.01860g Na2O).
T=26.3c=299.3K
Pressure=745mmHg=745torr
Pressure of N2=745-25.2=719.8torr
Generally, the equation for the ideal gas is mathematically given as
PV=nRT
Therefore
719.8/760=45.6/1000=n*0.0821*299.3
n=0.00176*14
In conclusion, the Mass of N2
M-N2=0.00176*14
M-N2=0.025gram

Answer:
CHARLES' LAW
given:
= 600 mL = 0.6 L
= 27 °C = 300.15 L
= 77 °C = 350.15 L
conversion:
= 600 mL (1 L / 1000 mL)
= 0.6 L
= 27 °C + 273.15 K
= 300.15 K
= 77 °C + 273.15 K
= 350.15 K
solution:
= ( × ) ÷
= (0.6 L × 350.15 K) ÷ 300.15 K
= 0.7 L
B Through the ground (earthquakes)
