How do you find the specific volume of R-134A at P=700 kPa and T= 120 C? I know it is from the tables but I can't seem to figure out how to get the number: v = 0.43358 m^3/kg

The acceleration of a rocket traveling upward is given by a = (8 + 0.02s) m/s2, where s is in meters.(Figure 1). Initially, v = 0 and s = 0 when t = 0.

Determine the time needed for the rocket to reach an altitude of s = 100 m .

Using the change of variables u=x^2y and v=y/x, integrate f(x,y) =x^2y^2 over the region bordered by y= 1/x^2,y= 3/x^2, y=x and y= 2x.

Part A: For the circuit shown in the figure(Figure 1) find the current through each resistor.

Part B: For the circuit shown in the figure find the potential difference across each resistor.
