Answer:
Part a)
![f_B = 290 Hz](https://tex.z-dn.net/?f=f_B%20%3D%20290%20Hz)
Part B)
percentage increase is
%
Explanation:
Part a)
As we know that the beat frequency is
![f_A - f_B = 3](https://tex.z-dn.net/?f=f_A%20-%20f_B%20%3D%203)
after increasing the tension the beat frequency is decreased and hence the tension in string B will increase
So we have
![293 - f_B = 3](https://tex.z-dn.net/?f=293%20-%20f_B%20%3D%203)
![f_B = 290 Hz](https://tex.z-dn.net/?f=f_B%20%3D%20290%20Hz)
Part B)
percentage increase in the tension of the string will be given as
![f_A - f_B' = 1](https://tex.z-dn.net/?f=f_A%20-%20f_B%27%20%3D%201)
![f_B' = 292 Hz](https://tex.z-dn.net/?f=f_B%27%20%3D%20292%20Hz)
now we have
![f = \frac{1}{2L}\sqrt{\frac{T}{\mu}}](https://tex.z-dn.net/?f=f%20%3D%20%5Cfrac%7B1%7D%7B2L%7D%5Csqrt%7B%5Cfrac%7BT%7D%7B%5Cmu%7D%7D)
so we have
![T_1 = C (290)^2](https://tex.z-dn.net/?f=T_1%20%3D%20C%20%28290%29%5E2)
![T_2 = C(292)^2](https://tex.z-dn.net/?f=T_2%20%3D%20C%28292%29%5E2)
so we have
![\frac{\Delta T}{T} = \frac{292^2 - 290^2}{290^2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5CDelta%20T%7D%7BT%7D%20%3D%20%5Cfrac%7B292%5E2%20-%20290%5E2%7D%7B290%5E2%7D)
percentage increase is
![percentage = 1.38](https://tex.z-dn.net/?f=percentage%20%3D%201.38)
Acceleration = (final velocity^2 - initial velocity^2) / 2 * distance
Acceleration = (19.1^2 - 9.2^2) / 2 * 32
Acceleration = (364.81 - 84.64) / 64
Acceleration = 280.17 / 64
Acceleration = 4.3777m/s^2

The scale would need 10 aluminum cubes on one side. Figure out how many paper clips would be needed on the other side to balance this. You have to use more than one aluminum cube because you need to have enough cubes so that you get a whole number mass. 10 cubes gives you a total mass of 27 g for the aluminum.
Answer:
Yes, since formations aren't mentioned at all in the rules, they can be adjusted. Sometimes when making a substitution, a coach will sub in a defender for an attacker/midfielder if the team is ahead and wants to protect their lead....

DOES GOD EXIST? That is one of the best.
