Which of the following is a good electrical conductor?plastic

concrete

wood

gold

Answers

Answer 1
Answer: Greetings!

The answer would be ~ Gold. All metals are good conductors. But some however may be slower than others. Gold is not that great of a conductor, but is the best choice on here.

Hope this helps!

As a longitudinal wave travels through a medium, it displaces the particles . parallel to the direction which the wave travels.b. along the opposite plane of travel.
c. vertically along the direction that the wave travels.
d. perpendicular to the path of travel.

Answers

As a longitudinal wave travels through a medium, it displaces the particles parallel to the direction which the wave travels.

What is longitudinal wave?

This type of waves are vibrations that takes place in the same direction i.e parallel to the wave motion. They are usually mechanical and examples include sound waves which requires a medium.

A longitudinal wave is a form of wave in which the displacement of the medium and the medium's vibration are both parallel to the direction of the wave.

A longitudinal wave moves the particles parallel to its direction of passage as it passes through a material.

Answers

The answer is current.

Current in the context of an electrical circuit is the flow of charge. Current is a quantity that is physical and can be measured. Current is defined as the rate of the flow charge past a certain point in a circuit. Current is expressed in Amperes which is equal to 1 coulomb/1second. 

Radiant heat transfers energy
A.) To nearby solid objects
B.) To the surrounding air

Answers

"One of the earliest methods of central heating involved the use of a boiler. In boiler systems, water is heated using a fossil fuel such as coal, oil, or propane. The water is allowed to convert to steam. It then travels through piping to the various rooms in the house. Each room has at least one radiator. As the name implies, heat energy radiates from this unit. When the heat energy (in the form of infrared waves) encounters solid objects in the room, those objects absorb the energy and warm up. Only a small amount of convection is involved in distributing heat from radiators."

"Radiant heat can also be obtained from electricity-based units. In these appliances, as electricity runs through wires, heat is generated. The wires may glow red. Again, this type of heat is radiated through the air and absorbed by solid objects. Many space heaters are radiant in design."

-Alpha Omega Academy, Unit 2 (Heat Flow), Assignment 5 (Heating Systems)

"Radiant heat passes through the air and heats solid objects making it highly efficient wherever it's installed. Because radiant heat is produced instantly, there is no need for expensive pre-heating. Infrared heaters provide heat and warmth quickly so you are able to save on the costs of heating seldom used areas."

-Article : How do radiant heaters work? - AEI Corporation

SO...

The answer is:

A) To nearby solid objects
