Are you getting this whistle when the car is stopped? If so, shut the radio off and see if it still exist. If it does, then shut the blower/fan down. If it goes away, then it is more than likely the bearings on the blower motor.
a high c
It starts at an E6 or the E flat above soprano high C
A flute has a high pich and a sorta low pitch. Low C or B on flute and pro flute are pretty low but high C on flute is REALLY high, but mostly it is high. If you want a really high instrument try the piccolo. If you are really good at flute go on the piccolo. Ihope I answered your question.
110 deg C = 230 deg F.110 deg C = 230 deg F.110 deg C = 230 deg F.110 deg C = 230 deg F.
that would be high pitch
230 degrees Celsius = 446 degrees Fahrenheit
-230 deg C = -382 deg F.
230°C = 446°F
C = (F-32)*5/9 so (230-32)*5/9 = 110°C
(-230) degrees Celsius = -382 degrees Fahrenheit.
One high pitched musical instrument is an Oboe. Other high pitched musical instrument include a flue and a piccolo.
We can change its pitch by finding the middle C so that we can be able to know which is high-pitched or low-pitched. If you want high pitch you play keys which are on the right. If you want low pitch you can play the keys which are on the left.
