Un automóvil se desplaza por una línea recta con movimiento rectilíneo uniforme, de manera tal que en 3 horas recorre una distancia de 360 Km. Calcular su velocidad.

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

Imagine that someone pushes one marble toward a motionless marble. would there still be action-reaction forces involved in the collision? how might the marbles’ motions be changed? ?

Which sections of the heating curve illustrate this process?
