Materials that allow electricity to flow are called

Correct Answer: Kinetic energy

Explanation:

Every object has two typea of energies. They are ::

Potential energy

Kinetic energy

 

If the object is in motion, then it has Kinetic energy (KE). Potential energy (PE) is energy that is "stored" because of the position and/or arrangement of the object.

 

Hence, another name for energy of motion is called Kinetic energy.

Correct Answer: Sunlight

Explanation:

A resource is a source or supply from which a benefit is produced. Resources can be broadly classified upon their availability they are renewable and non renewable resources.

 

Renewable Resources :: A resource that can be replenished after use are known as Renewable resources.

Examples :: Sunlight, Water, biomass,...

 

Non renewable Resources :: A resource that, once used, is no longer available are known as Non renewable Resources. 

Example :: Coal, fossil fuels, natural gas,...

 

Sunlight is the both renewable and inexpensive resource from the given options.

Correct Answer: collide each other

Explanation:

Heat energy can be transferred by three major methods. They are 

 

1. Conduction,

2. Convection and

3. Radiation.

 

Conduction is the movement of heat through a substance by the collision of molecules

Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy.

Radiation is the transfer of energy by means of photons in electromagnetic waves governed by the same laws. It occurs through a vacuum or any transparent medium.

Correct Answer: All of the above

Explanation:

We know that most of the metals are goof conductors of electricity and heat. Metals are very strong but they are malleable i.e, they can be bent into a shape. These are shiny when they are cut or polished. 

 

Hence, metals are malleable, conductors and luster. All the above are properties of the metals.

Correct Answer: Vacuum

Explanation:

Sound waves cannot travel through a Vacuum.

 

A vacuum is an area without any air, like space. So sound cannot travel through space because there is no matter for the vibrations to work in.

Correct Answer: Bicycle

Explanation:

Bicycle is a compound machine in the above given options. A compound machine is a machine that is formed by two or more simple machines.

Correct Answer: mass being converted to energy when protons and neutrons bind together in a nucleus

Correct Answer: Renewable energies

Correct Answer: Stope

Explanation:

These are called intrusive igneous rocks because the magma has intruded into pre-exiting rock layers. Types of intrusive igneous rocks are granite and basalt .

A batholith is the largest of the intrusive bodies.

Correct Answer: Cinema

Explanation:

Optical illusion is what that refers to persistence of vision with a principle that multiple images blend into a single image in human mind and what is showed in cinema.

 

Hence, Persistence of vision is the principle behind cinema.
