General Physics Question 9
Question 9
- Column II gives certain systems undergoing a process. Column I suggests changes in some of the parameters related to the system. Match the statements in Column I to the appropriate process (es) from Column II.
Column I
(A) The energy of the system is increased.
Column II
(p) System : A capacitor, initially uncharged. Process : It is connected to a battery.
(B) Mechanical energy is provided to the system, which is (q) System : A gas in an adiabatic container fitted with an adiabatic converted into energy of random motion of its parts. piston.
Process : The gas is compressed by pushing the piston.
(C) Internal energy of the system is converted into its mechanical energy.
(r) System : A gas in a rigid container. Process : The gas gets cooled due to colder atmosphere surrounding it.
(D) Mass of the system is decreased.
(s) System : A heavy nucleus, initially at rest.
Process: The nucleus fissions into two fragments of nearly equal masses and some neutrons are emitted.
(t) System : A resistive wire loop.
Process : The loop is placed in a time varying magnetic field perpendicular to its plane.
Show Answer
Answer:
Correct Answer: 10. A-p, q, s, t, B-q, C-s, D-s
Solution:
- (t) A time varying magnetic field will produce a nonconservative electric field. Due to this electric field, a current starts flowing in the resistive loop and heat is produced.
