You are given two same party balloons (one filled with helium and the
second is empty and rolled), the scale, graduated mass of 100 grams, and
a pile of paper clips. show how you would:
• calculate the volume of the balloon (no ruler).
• how many balloons you would need to lift 126lbs science olympian?

What term do psychologists use to designate our personal awareness of feelings, sensations, and thoughts?

Crowbar of 5 metre is used to lift an object of 800 metre if the effort arm is 200cm calculate the force applied

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)
