1. The sign of a floating point number depends on the sign of mantissa only.
2. If the absolute value of a number is less than 1, the sign of exponent is zero or positive.
3. With sign bit of mantissa as 0, increasing the exponent from a positive to a more positive value gives a larger floating point number.

Assertion (A): Transient periods are of short duration but can result in dangerously high voltages and currents.

Reason (R): Circuit equations in transient analysis are integral differential equations.

1. Coordination number is four.
2. Packing fraction is 0.34
3. Copper crystallizes into diamond structure
4. Lattice is FCC.
