You ride your bike at 11.5 m/s directly away from your neighbor's trumpet sound and toward the sound of another neighbor's trombone and find that you hear both instruments at exactly the same pitch. the trumpeter is practicing her middle c at a frequency of 262 hz . what frequency is the trombonist producing

245 Hz

Explanation:

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

Frequency of trumpet = f = 262 Hz

Speed of bike = 11.5 m/s =

Applying doppler effect

For the trombone moving towards it

So, frequency of the trombonist is 245 Hz

answer would be d.) i hope this

explanation:

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
