Assertion: The fundamental frequency of an open organ pipe increases as the temperature is increased. Reason: As the temperature increases, the velocity of sound increases more rapidly than length of the pipe.
Assertion: Resistivity of a metal conductor increases with the increase in temperature. Reason: When the temperature of a conductor is increased then the number of free electrons per unit volumic increases.
Statement-1: Kinetic energy of photoelectrons increases with increases in the frequency of incident radiation Statement-2: The number of photoelectrons ejected increases with increases in intensity of incident radiation.
A paramagnetic material is placed in a magnetic field. Consider the following statements : (A) If the magnetic field is increased, the magnetization is increased. (B) If the temperature is increased, the increased the magnetization is increased.
