When discussing discordant and harmonious sound waves, which statement is false? A. Both types of waves are the result of compon
ent waves with different frequencies. B. Knowing the frequencies of the original waves is useful in determining if the result will be discordant or harmonious. C. Low ratios of the frequencies of the original and resultant waves indicate discordant waves. D. If the original waves combine to form irregular displacements of air, the sound will be discordant.
When discussing discordant and harmonious sound waves, the
statement that is false is knowing the frequencies of the original waves is
useful in determining if the result will be discordant or harmonious. The
answer is letter B.
B) Knowing the frequencies of the original waves is useful in determining if the result will be discordant or harmonious
Explanation:
The sound is generated when something vibrates. The vibrating body produces the mechanism around it to vibrate. Vibrations in the air are described as traveling longitudinal waves, which we can hear. Sound waves comprise of areas of high and low pressure named compressions and rarefactions.
According to newton's third law of motion, when a hammer strikes and exerts force to push it into a piece of wood, the nail <span>C. exerts an equal or opposite force on the hammer. The third law of motion states that every action has an equal BUT opposite reaction. This means that the nail exerts the same force the hammer exerts on it.</span>
The so-called greenhouse effect is observed only in houses painted green, and even there, only between the hours of 2PM - 4PM local time on Thursday afternoon.
As the ball falls from C to E, potential energy is converted to kinetic energy. The velocity of the ball increases as it falls, which means that the ball attains its greatest velocity, and thus its greatest kinetic energy
