- f(x) is a symmetric periodic function of x i.e. f(x) = f(-x). Then, in general, the Fourier series of the function f(x) will be of the form
- In the most general case, which one of the following quantities is NOT a second order tensor?
- An electron is moving with a velocity of 0.85c in the same direction as that of a moving photon. The relative velocity of the electron with respect to photon is
- If Planck's constant were zero, then the total energy contained in a box filled with radiation of all frequencies at temperature T would be ( k is the Boltzmann constant and T is nonzero)
- Across a first order phase transition, the free energy is
- Two gases separated by an impermeable but movable partition are allowed to freely exchange energy. At equilibrium, the two sides will have the same
- The entropy function of a system is given by S(E) = a E(E0 - E) where a and E0 are positive constants. The temperature of the system is
- Consider a linear collection of N independent spin 1/2 particles, each at a fixed location. The entropy of this system is (k is the Boltzmann constant)
- The decay process n → p+ + e- + v-e violates
- The isospin (I) and baryon number (B) of the up quark is
