1.	In a CE transistor amplifier, there is a current and voltage gain associated with the circuit. In other words there is a power gain. Considering power a measure of energy, does the circuit violate conservation of energy ?
Answer» In CE transistor amplifier, the power gain is very high. In this circuit, the extra power required for amplified output is obtained from DC source. Thus, the circuit used does not violet the law of conservation.

A bone containing `200 g` carbon-14 has `beta`-decay rate of `375` decay/min. Calculate the time that has elapsed since the death of the living one. Given the rate of decay for the living organism is equal to `15` decay per min per gram of carbon and half-life of carbon-14 is `5730 years`.A. 22920 yrB. 11460 yrC. 17190 yrD. None of these
Fusion processes, like combining two deuterons to form a He nucleus are impossible at ordinary temperatures and pressure. The reasons for this can be traced to the fact: (a) nuclear forces have short range. (b) nuclei are positively charged. (c) the original nuclei must be completely ionized before fusion can take place. (d) the original nuclei must first break up before combining with each other.
