Answer:
Container A and C
Explanation:
ideal gas equation gives P=nRT/V
so at constant Temperature and pressure, P=n/T
Container A and C after dividing number of moles and Volume, are found to be the same=0.0446
Answer:
The wavelength of the sound waves are, λ = 26.92 m
Explanation:
Given data,
The frequency of the sound waves, f = 13 Hz
The speed of sound waves in air, v = 350 m/s
The velocity of the wave in the medium is equal to the product of its wavelength and its frequency.
The formula for the wavelength of the waves is,
λ = v / f
Substituting the given values in the above equations,
λ = 350 m/s / 13 Hz
= 26.92 m
Hence, the wavelength of the sound waves are, λ = 26.92 m
Answer:
How does each sum relate to the energy of the absorbed photon? the total energy of each set of emitted photons is equal to the energy of the absorbed photon.
Explanation:
The cannon is much heavier than the cannonball, so it has the same momentum, but not the same velocity. The cannonball has less mass to overcome, so it accelerates more quickly.
Answer:
Particles vibrate parallel to the direction the sound travels
