A sample of an ideal gas goes through the process. From Ato B, the process is adiabatic; from Bto C, it is isobaric with 345 kJ of energy entering the system by heat; from Cto D, the process is isothermal; and from Dto A, it is isobaric with 371 kJ of energy leaving the system by heat. Determine the difference in internal energy Eint ,B 2 Eint ,A . 1 3 P(atm) 0.09 0.20.4 1.2 A C B D V(m 3 )

Give your knowledge of these things in your paper, you will compare and contrast analog and digital signals to determine which is more reliable for encoding and transmitting information. you’ll compare these features: signal shape numerical values for signal measurements amount of data that can be transmitted energy requirements privacy and security (ability of the signal to be encoded in a secret code) clarity of signal in the space provided, write down what you already know about any of these features. if you’re not sure, write down questions you might have about the features.

Astone weighing 1.5 kilograms is resting on a rock at a height of 20 meters above the ground. the stone rolls down 10 meters and comes to rest on a patch of moss. the gravitational potential energy of the stone on the moss is joules.

If the chemical properties of a substance remain unchanged and appearance or shape of a substance changes it is called a ?
