Cilindrii din figura de mai jos sunt fixati conform desenului. Pistoanele avand ariile S1=100cm^2 respectiv 50cm^2, sunt uniti cu o tija rigida. In interiorul vaselor se gaseste aer la temperatura 27C si presiunea normala. Aerul din cilindrul mai mic este incalzit cu 50C. Cu cat trebuie modificata temperatura aerului din cilindrul celalalt pentru ca pistoanele sa ramana in aceeasi pozitie?

Asap and show ! a 14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.
