Some components like transformers and inductors cannot be integrated into an IC except for very specialized high frequency applications. They have to be connected externally to the semiconductor pins. In general, transformers are located in circuit boards as separate components and cannot be integrated into semiconductor based integrated circuits.

Correct Option: C

In addition to transmitting frames directed to a single address, local area networks are capable of sending frames directed to a group of address, called a multicast address, which can be received by a group of stations.They can also send frames directed to all stations using the broadcast address. A frame sent to multicast destination address can be received by all stations configured to listen for that multicast address.

Graphite is a good conductor of electricity because its electrons are delocalized or free to move around. Each carbon atom in graphite is directly linked to only three carbon atoms through covalent bonds. Therefore, out of the four valence electrons in a carbon atom, only three are used for bonding and the fourth is relatively free and can move from one carbon atom to the other.

Correct Option: A

In physics, electromagnetic radiation (EMR) refers to the waves (or their quanta, photons) of the electromagnetic field, propagating (radiating) through space carrying electromagnetic radiant energy. It includes radio waves, microwaves, infrared, (visible) light, ultraviolet, X-, and gamma radiation.

When a fresh egg is placed in regular water, it sinks. However, when the same egg is placed in salt water, it floats. This is because salt water is denser than the egg causing it to float.
