Answer;

B. the source producing the overtones in the sound

Explanation;

-Sound quality describes the characteristics of the sound which allow the ear to distinguish sounds which have the same pitch and loudness. The quality or timbre of a sound depends on its wave form, which varies with the number of overtones, or harmonics, that are present, their frequencies, and their relative intensities.

-The source producing the overtones in the sound does not affect the timbre or the quality of sound and thus it is not taken into consideration when describing the quality of a sound.

We often use a spoon to cool coffee by stirring. Some of the heat is conducted from the coffee to the air by this method, but th
Ilia_Sergeevich [38]

Answer:

Explanation:

heat lost by coffee = heat gain by aluminum spoon

heat lost by coffee = mc ( 85° C - T)

175 ml of water = 175 grams

175 grams = (175 / 1000) kg = 0.175 kg

heat loss by coffee = 0.175 × 4182 J/Kgk ( 85 - T) = 731.85 ( 85-T) = 62207.25 - 731.85 T

heat gain by aluminum spoon = 0.012kg × 897 J/kgK ( T - 22) = 10.764 T - 236.808

10.764 T - 236.808 = 62207.25 - 731.85 T

10.764 T + 731.85 T = 62207.25 + 236.808

T = 84.086 ° C approx 84°C

Why cant the moon be eclipsed when it is halfway between the nodes of its orbit?
Eddi Din [679]

The reason why the moon can't be eclipsed when it's halfway between the nodes of the orbit because the moon's orbit is at it's maximum deviation, meaning that it is leaving it's course from the sun's path, which would make the shadow fall way below or above the moon. Because of that, the moon can't eclipsed.

If the frequency of oscillation of the wave emitted by an fm radio station is 92.4 mhz, determine the wave's period of vibration
lapo4ka [179]
The basic relationship between the frequency of a wave and its period is
f= \frac{1}{T}
where f is the frequency and T the period of vibration.

In our problem, the frequency is 
f=92.4 MHz = 92.4 \cdot 10^6 Hz
so, by re-arranging the previous formula, we can find the period of the wave:
T= \frac{1}{f}= \frac{1}{92.4 \cdot 10^6 Hz}=1.1 \cdot 10^{-8} s

A race car is one lap behind the lead race car when the lead car has 44 laps to go in a race. If the speed of the lead car is 55
masha68 [24]

Answer:

Speed of second car will be 57.17 m/sec

Explanation:

We have given lead car travels = 44 laps

1 laps = 1.34 km = 1340 m

So total distance = 1340×44 = 58960 m

Speed of lead car = 55.9 m/sec

We know that time=\frac{distance}{speed}=\frac{58960}{55.9}=1054.74sec

As the second car is 1 lap behind so distance traveled by second car = 45×1340 = 60300 m

So speed of second car will be speed=\frac{distance}{time }=\frac{60300}{1054.74}=57.17m/sec
