When a system returns back to its initial state after passing by dissimilar phase, the phenomena is said to be a cyclic process. In this process as ΔU = 0.
From first law of thermodynamics,ΔQ = W
Thus in a cyclic phenomena, the heat absorbed by the system is equivalent to the net work done by the object. Work done is the area of the cycle on the PV diagram.
Hello, As a part of a school assignment, I need to conduct a Q & A with an expert in a field of my choosing. The field I have chosen is the "physics of rollercoasters". If you wo

Five coulombs of charge are placed on a thin-walled conducting shell. Once the charge has come to rest, the electric potential inside the hollow conducting shell is found to be:
A single-phase transformer has 2000 turns on the primary and 800 turns on the secondary. Its no-load current is 5A at a power factor of 0.20 lagging. Assuming the volt drop
Displacement: - The modification in position of a body in a certain direction is known as displacement. It is a vector function and its unit in SI system is meter.
State and prove law or Parallelogram of Froces
Newton's Law of Gravitation In 1687, Newton did not "discover" gravity but he did figure out that gravity is universal. It makes a ball fall when you drop it on earth. It also
What is the Directionality of LASER? Directionality: Laser emits light which is highly directional. Laser light is emitted like a relatively narrow beam in an exact direction.
Explain the Natural Frequencies and Resonance Standing waves occur when the waves, like those in a vibrating piece of rope, are repeating so that there are places on the rope t
Q. A capacitor blocks d.c. but allows a.c. Why? Capacitive reactance XC = 1/ω C = 1 / 2πν C Where ν is the frequency of the a.c. supply. In a d.c. circuit
