Answer:
The two possible frequencies of the other player's note are 437.3 Hz and 442.7 Hz
Explanation:
Given Data
f₁=440 Hz
fₐ=2.7 beats per seconds
The beat frequency is equal to the difference in the frequencies of the two original waves:
So
f
=|(f₁±fₐ)|
First to Solve for (-) Sign we get
f=|(440-2.7)|
f=437.3 Hz
Now for Solve for (+) Sign we get
f=|(440+2.7)|
f=442.7 Hz
The two possible frequencies of the other player's note are 437.3 Hz and 442.7 Hz

It is important to pay attention to the fundamental units in the given information of physics problems; if you carefully arrange a system so the units cancel out appropriately, the answer is usually correct.
Force is mass x acceleration<span>, </span><span>and the units of force are (Kg/m</span>·s²). In this system, a 10 Kg system is accelerated by 5 m/s². Simply multiply:
10 Kg x 5 m/s² = 50 Kg·m/s² = 50 Newtons
