Answer:

We have two possible values for the second tuning fork

443Hz and 337Hz

Explanation:

When two waves of slightly different frequency interfere, they produce beats and the frequency of the beats (fb) is:

f_{b}=\mid f_{1}-f_{2}\mid

with f1 the frequency of the first tuning fork and f2 the frequency of the second tuning fork, so we should solve

3=\440-f_{2}\mid

note that it is the absolute vale of the rest between f1 and f2 so we have two equations and two possible values:

3=440-f_{2}

f_{2}=337Hz

and

-3=440-f_{2}

f_{2}=443Hz

compare the different ways a musician changes the pitch while playing a stringed instrument or playing a wind instrument
alexdok [17]
(This is from experience so sorry if it's wrong but) When wind instruments are played, sometimes the notes go flat or sharp depending on the speed the player blows air into the instrument as well as the warmth of the air. When playing a string instrument, the pitch can be changed in many ways. For example, when the player places their fingers on the string depending on which part of the tip of the finger you use, the tone of the sound and sometimes the pitch, changes. Looking at the question in a different way, you can change the pitch and the range of notes you can reach on the instrument (both wind and string) by changing the note you tune your instrument to. Hope this helps!!

Technician A says that front bearing assembly locknuts for RWD vehicles are typically heavily torqued to maintain the bearing ad
Burka [1]

Answer:

B. Technician B

Explanation:

The statement made by Technician A is not right because for an RWD vehicles, its front bearing assembly is not used for sustaining the bearing adjustment. The statement made by the Technician B is right because the main reason for staking the bearing assembly of the wheel of a FWD vehicle is to ensure that the torque is at a specific value. Thus, only Technician B is correct.
