    Energy changes upon insertion of a solid dielectric in a capacitor

    Thanks a lot for your reply. Well I'm a high school student and I don't have much knowledge regarding the devices you've mentioned. I'm highly constricted within my course syllabi. I would be happy if you throw some light on energy losses on insertion of dielectric at constant voltage ( a DC...

    Energy changes upon insertion of a solid dielectric in a capacitor

    Consider a simple circuit consisting of a battery and a parallel plate capacitor .During the process of charging of capacitors, we come to learn that half of the work done by the battery is stored in the form of potential energy and half of it is lost as heat or electromagnetic radiation...

    Confusion with multiple impulses

    Well for my concerns you can assume that the body deforms and nothing pierces the body. The body can soon reform to gain it's original shape making the collision elastic. My concerns are regarding whether the impulsive normal, as mentioned above start to act as soon as I initiate a contact...

    Confusion with multiple impulses

    Suppose I have a body of mass M kept on a horizontal smooth surface. I strike that particle with some force ,providing an impulse J_1. The applied force is in vertically downward direction. Suppose that the body deforms in this process and it doesn't rebound. What I want to know is, whether the...

    Cyclic Thermodynamic processes

    Sir, I'm not really comfortable with the idea that a system can reach it's initial state after undergoing Irreversible cyclic process. Here are my concerns regarding entropy change for an irreversible process. Although I'm not much aware about entropy but I know 2 facts regarding it. The first...

    Cyclic Thermodynamic processes

    Sir if a system undergoes an irreversible process will it reach the same state as before for example same temperature pressure and volume? And is it possible to plot an irreversible cyclic process on a graph even if it's not in equilibrium with the surroundings? (These are the probable reasons I...

    Cyclic Thermodynamic processes

    By cyclic processes I mean the processes in which a system starting from the initial state returns to the same passing through other states( it's usually shown as a continuous closed curve in the P-V diagram of the gas undergoing the process) for eg. Suppose you reversibly compress a gas and...

    Cyclic Thermodynamic processes

    Here's a link to cyclic Thermodynamic processes mentioned by me above https://en.m.wikipedia.org/wiki/Thermodynamic_cycle

    Cyclic Thermodynamic processes

    Basically what I'm trying to ask is if I'm given a case of cyclic processes does this always mean that it's reversible. Well I think the engines are undergoing irreversible yet cyclic processes. Although I'm not sure about this.

    Cyclic Thermodynamic processes

    I'm a high school student with basic knowledge about thermodynamics. I have always come across systems under going reversible cyclic processes. Are there any cases for irreversible cyclic processes? Thanks in advance.

    B Need a bit more clarification on W=F.ds

    I'm talking about centre of mass energy above.

    B Need a bit more clarification on W=F.ds

    So How would you explain the situation ?

    B Need a bit more clarification on W=F.ds

    For example a rope falling from a desk{with a hole} I can write the centre of mass energy but I can't proceed further.

    B Need a bit more clarification on W=F.ds

    In the above case I have tried to proceed from centre of mass energy to conservation of energy for a rigid body. Can anybody help me out on how does this work for non rigid bodies like ropes.
