Jamal wanted only to test the effect of the free fall and so he put his system in a vacuum to prevent air resistance. in free fall, will the crumpled or flat paper reach the ground first?

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat

Which of these is not a possible type of energy transformation? a. electrical energy into light energy b. sound energy into nuclear energy c. potential energy into kinetic energy d. kinetic energy into mechanical energy

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.
