Awater tank has dimension of 6m*4m*4m. fimd the pressure exerted by water at the base of bam when it is half filled.(density of water =1000kg/m cube acceleration due to gravity is 9.8 m/s square

1. a net force of 100 newton’s is applied to a wagon for 5 seconds. this causes the wagon to undergo a change in momentum of

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)

Work = force × a. work b. energy c. distance d. momentum
