What is the major point of adding safety features in vehicles?

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

Blank liquids and gases exert a buoyant force on objects placed in them

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