The A string on a cello vibrates in its first normal mode with a frequency of 220 Hz. The vibrating segment is 67.0 cm long and has a mass of 1.70 g. (a) Find the tension in the string.
N
(b) Determine the frequency of vibration when the string vibrates in three segments.
Hz

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

an energy transformation flow diagram is shown

where is it ?

i'm on my way to history not a mistory.

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
