Write the method drawSquare below. /** Precondition: 0 ≤ x < 10, 0 < y ≤ 10, and len > 0.

* Draws a square on a 10-by-10 xy-coordinate grid

* and prints the square’s side length and area.

* The upper left corner of the square will be located

* at the coordinate (x, y) and the side length of the

* square will be len (or as large as will fit in the grid).

At steady state, air at 200 kpa, 325 k, and mass flow rate of 0.5 kg/s enters an insulated duct having differing inlet and exit cross-sectional areas. the inlet cross-sectional area is 6 cm2. at the duct exit, the pressure of the air is 100 kpa and the velocity is 250 m/s. neglecting potential energy effects and modeling air as an 1.008 kj/kg k, determine ideal gas with constant cp = (a) the velocity of the air at the inlet, in m/s. (b) the temperature of the air at the exit, in k. (c) the exit cross-sectional area, in cm2
