Assertion (A): A graph can have many trees.

Reason (R): The number of tree branches is equal to number of nodes.

1. An arithmetic operation between integer and an integer gives integer as the result.
2. An arithmetic operation between a real and a real constant gives real constant as the result.
3. An arithmetic operation between an integer constant and a real constant is not valid.

Assertion (A): For a dielectric, P = ∈₀(∈_r - 1) E.

Reason (R): Dipole moment per unit volume is called polarization of dielectric.

Assertion (A): Temperature control of the passenger compartment of car uses both feed forward and feedback controls.

Reason (R): Feed forward control gives corrective action before the disturbance affects the output and feedback control applies corrective action after output changes.

1. If a coil with resistance R is connected in direct measurement mode and if the residual resistance of Q-meter is 0.1 R, then the measure Q of the coil would be 1.1 times the actual Q.
2. If the inductance to be measured is less than 0.1 mH, the error due to presence of residual inductance cannot be neglected.
3. The presence of distributed capacitance in a coil modifies the effective Q of the coil.

1. A function can be called any number of times.
2. A function gets called when the function name is followed by a semicolon.
3. The order in which functions are defined in a program and the order in which they are called must be the same.
