Apiston-cylinder arrangement contains air modeled as an ideal gas with constant specific heat ration of k =1.4. the air undergoes a power cycle consisting of four processes in series: process 1 to 2: constant temperature expansion at 600 k from p_1 = 0.5 mpa to p_2 = 0.4 mpa. process 2 to 3: polytrophic expansion with n = k to p_3 = 0.3 mpa process 3 to 4: constant pressure compression to v_4 =v_1 process 4 to 1: constant volume heating. sketch the cycle on a p-v diagram. determine (a) the work and heat transfer of each process in kj/kg and (b) the thermal efficiency.

Two technicians are discussing a resistance measurement between the can-h and can-l wires. technician a says this measurement should be done with the ignition switch in the "run" position. technician b states that a measurement of 0 ohms indicates an open in the network. which technician is correct?

Two vectors are shown. which statement best compares the vectors? vector x has greater magnitude than vector y. vector y has greater magnitude than vector x. the vectors have the same displacement. the vectors have the same direction.

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
