Singing that is off-pitch by more than about 1% sounds bad. How fast would a singer have to be moving relative to the rest of a band to make this much of a change in pitch due to the Doppler effect

-3.396 m/s or 3.465 m/s

Explanation:

v = Speed of sound in air = 343 m/s

= Relative speed of the singer

f = Observed frequency

f' = Actual frequency

1% change can mean

From the Doppler effect equation we have

The velocity is -3.396 m/s

when

The velocity is 3.465 m/s

find the sum of the two horizontal vectors and the sum of the two vertical vectors

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
