Explain how an antenna works in an early radio.(1 point)
Both fiber optic and metal cables transmit the same quality signal. However, metal cables use light to transmit the data, whereas fiber optic cables do not.

Both fiber optic and metal cables transmit the same quality signal. However, fiber optic cables use light to transmit the data, whereas metal cables do not..

Both fiber optic and metal are used to transmit signals across long distances. However, metal cables use light to carry signals making them much faster and higher quality.

Which statement describes the transfer of heat between two objects?(1 point)

Particles bump into each other and transfer matter. This can be detected by a change in temperature.

Particles bump into each other and transfer energy. This can be observed directly with the human eye.

Options d and option c for the question 1 and 2 are true. Electrons move up and down the transmitter antenna as electricity flows into it, creating radio waves.

What is a radar antenna?

A radar antenna is a device that sends out radio waves and listens for their reflections. The ability of an antenna to identify the exact direction in which an item is placed determines its performance.

An antenna works in an early radio as;

Signals are sent across vast distances using both fiber optics and metal. Fiber optic cables, on the other hand, use light to transmit signals, making them considerably quicker and of greater quality.

The statement describes the transfer of heat between two objects;

When particles collide, energy is transferred. A change in temperature can be used to identify this.

An antenna works in an early radio will be ;

1)Electrons move up and down the transmitter antenna as electricity flows into it, creating radio waves.

2) Radio waves move at the speed of light through the air.

3) When the waves reach the reception antenna, they cause electrons within it to vibrate.

Hence,options d and option c for the question 1 and 2 are true.
