A confined quantity of air undergoes two thermodynamic processes departing from an initial equilibrium state where the temperature is 20°C, the absolute pressure is 1bar, and the volume is 0.2m3. First, the volume of the system is doubled by an isobaric process. Then, the volume is decreased back to the initial value through a process where the relation P-V1.4 is kept constant. You may assume average values for the particular heat capacities (cp and cv) to:
(a) Sketch the processes in a P-V diagram.
(b) Determine the temperature of the three states in K.
(c) Calculate the total work in kJ.
(d) Compute the total heat transfer in kJ.
Two faultlessly conducting spheres are in an evacuated region of space. One is at a potential of -1200 volts as well as the other is at a potential of 1500 volts. A free electron i
The light passing through a quarter wave plate is analysed by a rotating Nicol prism. It is get that the intensity of the emergent light beam from the rotating Nicol prism becomes
Resistance in Parallel: When two or more resistance are linked in such a way that one end is of the every resistor is connected to one terminal of the battery whereas the other
What can justify the use of fiber optic? In the huge majority of tasks, using traditional implies, the amount of light used is far in excess to the quantity really required. Mo
how much energy is required to raise an object of 300g that is initially at rest to a height of 2m and simultaneuosly give the object a velocity if 4m/s?
Force: Force may be defined as a push or a pull upon an object. In the English system the pound (1b) is used to express the value of a force. For example, we say that a force
Write the relation for the force acting on a charge carrier q moving with a velocity by a magnetic field in vector notation. Using this relation, reduce the conditions under which
A 0.15 kg glider is moving to the right on frictionless horizontal air track with speed of 0.8 m\s. It has a head on collision with 0.3 kg glider that is moving to the left with a
