In the diagram, q1, q2, and q3 are in a straight line. Each of these particles has a charge of -2.35 x 10-6 C. Particles
q1 and q2 are separated by 0.100 m and particles q2 and
q3 are separated by 0.100 m. What is the net force on
particle q1?

The graph below represents the work done by a student while running up flights of stairs. determine the student's power output after 10 seconds: 1600 j/s 8000 j/s 160 j/s 800 j/s

Anybody wanna ? (picture included? )

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)
