Two violinists are trying to play in tune. however, whenever they play their a string at the same time they hear a beat frequency of 3.0 hz. one of the violinists measures with an electronic tuner and finds her a string is at 422 hz. what are the possible frequencies for the a string of the other violinist?

the possible frequencies for the A string of the other violinist is 419 Hz

Explanation:

given information:

= 3 Hz

the frequency of the first violinist = 422 Hz

to find the possible frequency of the other violinist, we use the following equation':

= l - l

3 = l 422 - l

= 422 - 3

= 419 HZ

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.

the force required to move the cart is divided by three or 33.33 n.
