Who first flew a kite into the thunder clouds on a stormy weather to prove that the lightning in the clouds and the sparks produced in our charged clothes are basically of the same nature?

1 point

Michal Faraday (1803)

Isaac Newton (1672)

Benjamin Franklin (1752)

Alexandro Volta (1794)

Clear selection

The ancient Greeks discovered as early as 600 B.C. that when amber was rubbed with cat's fur, it attracted pieces of light objects such as hair. This is due the fact that both the bodies acquire :

1 point

Electrical charges

Static electrical charges

Moving electrical charges

Magnetic properties

Clear selection

What is the name of the scientific instrument used in earlier days to detect the presence of electric charges on a body by the motion of a test object due to the application of Coulombic electrostatic forces?

1 point

Voltmeter

Seismograph

Electroscope

Ammeter

Clear selection

Electrical charge can be transferred from a charged object to another through a :

1 point

Ebonite rod

Column of air

Column of water

Metallic conductor

Clear selection

The process of transferring of charge from a charged object to the ground is called :

1 point

Bypassing

Discharge

Earthing.

Induction

Clear selection

How does the Lightning Conductor rod protect a building from the effect of lightning?

1 point

The rod provides a barrier between the charged clouds and the building.

The rod neutralizes the electric charges present in the clouds during a lightning.

The rod provides an easy route for the transfer of electric charge from the lightning to the ground.

The rod increases the height of the building so that the damaging impact of the lightning becomes less.

Clear selection

An earthquake occurs due to the:

1 point

Volcanic eruption

Disturbances inside the earth's interior

Collision of Tectonic plates

Disturbances on the earth's crust

Clear selection

The boundaries of tectonic plates are the weak zones where earthquakes are more likely to occur. These zones are called :

1 point

Colliding zones

Vulnerable zones

Tectonic zones

Fault zones

Clear selection

An instrument used to record the seismic waves produced due to an earthquake is called :

1 point

Richter meter

Earthquake meter

Seismic meter

Seismograph

Clear selection

The the point on the Earth's surface directly above the point of origin of an earthquake is called :

1 point

Epicentre

Focus

Hypocentre

Centre

Clear selection

The the point point of origin of an earthquake located below the Earth's surface is called :

1 point

Epicentre

Focus

Hypocentre

Centre

Clear selection

Which scale is generally used to measure the intensity of an earthquake ?

1 point

Logarithmic scale

pH scale

Richter scale

Beaufort scale

Clear selection

An undersea earthquake might sometimes trigger a :

1 point

Volcanic eruption

landslide

Tsunami

Strong oceanic current

Clear selection

How does a lightning discharge take place in air although air is a bad conductor of electricity ?

1 point

The water vapour present in the air is actually a good conductor of electricity.

The flow of air within the clouds transfers electric charges during a lightning.

Air starts conducting during a rainy weather.

When the magnitude of the accumulated charges becomes very large, the air which is normally a bad conductor of electricity, is no longer able to resist the flow of charges.

Clear selection

The tectonic plate that lies north of the Indian plate and Arabian Plate comprising the vat landmass of Asia and Europe is called:

1 point

North American Plate

Indo-Australian Plate

Pacific Plate

Eurasia Plate

Clear selection

What is the name of the electrical charges produced on a glass rod by rubbing it with a silk cloth?

1 point

Stationary Charges

Static electricity

Current electricity

Charges at rest

Clear selection

How much on a Richter scale do destructive earthquakes measure ?

1 point

Higher than 7

Higher than 8

Higher than 9

Higher than 10

Clear selection
