The correct answer is (b.) conductor. A material that provides little or no resistance to the flow of electric current is called a conductor. A conductor is a known material that is used for a smooth flow of current with any barrier in one or more directions.

The correct answer is B) Conductor

A conductor is a material that allows for the flow of electrical charge (electrical current). This type of material provides little or no resistance to the flow of electric current. This is due to the fact that these type of materials have free electrons which conduct the flow of electrical current in any direction.

Different types of conductors have different resistances. Some types of materials are good conductors whereas some are not so good.

Some common conductors are Copper, gold, silver and aluminium.

An insulator is the an object of type of material which have a strong resistance to the flow of electric current. Some common insulators are glass, wood and plastic.

Block A of 5 kg with a speed of 3 m/s collides with block B of 10 kg that is stationary. After the collision, block B travels wi
Lemur [1.5K]

Answer:

-1m/s

Explanation:

We can calculate the speed of block A after collision

According to collision theory:

MaVa+MbVb = MaVa+MbVb (after collision)

Substitute the given values

5(3)+10(0) = 5Va+10(2)

15+0 = 5Va + 20

5Va = 15-20

5Va = -5

Va = -5/5

Va = -1m/s

Hence the velocity of ball A after collision is -1m/s

Note that the velocity of block B is zero before collision since it is stationary

Radio waves are readily diffracted around buildings, whereas light waves are negligibly diffracted around buildings. This is bec
Tom [10]

Answer:

Radio waves have longer wavelength

Explanation:

Radio wave is an electromagnetic frequency that has the ability to travel through long distance. They have frequencies shuttling been the range of 10^4 hz and a frequency of 10^12 hz

Light wave is also called visible light. This is because it is visible to the naked eye, despite it being in the electromagnetic spectrum. It's frequency is usually between 4*10^-7 hz and a frequency of 7*10^-7 hz.

As can be seen from both, the radio waves length are quite far stronger than that of the light waves.
