Two steel guitar strings have the same length. String A has a diameter of 0.60 and is under 450.0 of tension. String B has a diameter of 1.4 and is under a tension of 830.0. Find the ratio of the wave speeds, , in these two strings.
An ideal gas's initial conditions are 1 mol, a pressure of 271.7 kPa, an internal energy of 624 J and a volume of 0.8 L. The gas is allowed to expand quasi-statically at constant pressure to a volume of 6.9 L. It is then cooled at constant volume unt..
