2 .

Study of the sun is called

Seismography

Coronagraphy

Helioseismology

Heliography

Correct Answer : Helioseismology

Helioseismology is the study of the solar interior using observations of waves on the Sun's surface. Helioseismology, a term coined by Douglas Gough, is the study of the structure and dynamics of the Sun through its oscillations. These are principally caused by sound waves that are continuously driven and damped by convection near the Sun's surface. It is similar to geoseismology, or asteroseismology (also coined by Gough), which are respectively the studies of the Earth or stars through their oscillations. While the Sun's oscillations were first detected in the early 1960s, it was only in the mid-1970s that it was realized that the oscillations propagated throughout the Sun and could allow scientists to study the Sun's deep interior.

The modern field is separated into global helioseismology, which studies the Sun's resonant modes directly, and local helioseismology, which studies the propagation of the component waves near the Sun's surface.

3 .

The Biggest cause of Foodborne Illness is

Virus

Toothpick

Employee snacking

Poor Hygiene

Correct Answer : Poor Hygiene

The Biggest cause of Foodborne Illness is Poor Personal Hygiene.

Foodborne Illness is caused by consuming contaminated foods or beverages. Many different disease-causing microbes or pathogens can contaminate foods, so there are many different types of foodborne illnesses.

4 .

What type of mirror is used in car headlights?

Concave

convex

Both (a) & (b)

None of the above

Correct Answer : Concave

Concave type of glasses are used in the headlights of the vehicles as the light from the bulb which is at focus will converges out and spreads and reflects back parallely.

5 .

MONEX is associated with

Monsoon experiment

Monetary experiment

Montreal experiment

Lunar experiment

Correct Answer : Monsoon experiment

Monsoon experiment is abbreviated as MONEX.

The Monsoon Experiment is the core of the GARP Monsoon Subprogramme, which is a major international effort to achieve a better understanding of the Planetary monsoon circulation, the major seasonal perturbation of the general circulation of the atmosphere and the influence of the annual cycle of precipitation associated with the monsoon on the agriculture of the many populous nations of the region.

Hence, MONEX is associated with The Monsoon Experiment.

6 .

Fear of crossing road is called as

Erythrophobia

Agoraphobia

Emetophobia

Aerophobia

Correct Answer : Agoraphobia

Fear of places and situations that might cause panic, helplessness or embarrassment is called Agoraphobia. Fear of crossing road causes some panic in them and comes under Agoraphobia.

7 .

Thermal energy is caused by the motion of

molecules

atoms

Both (a) & (b)

None of the above

Correct Answer : Both (a) & (b)

* Thermal energy is caused by the motion of atoms and molecules in the matter.

* Thermal energy is an example of kinetic energy, as it is due to the motion of particles, with motion being the key.

* Thermal energy results in an object or a system having a temperature that can be measured.

* Thermal energy can be transferred from one object or system to another in the form of heat.

8 .

Delonix regia Rafin is the scientific name of

Gulmohar

Banyan

Chiku

Tamarind

Correct Answer : Gulmohar

9 .

What color does yellow and green make?

Ocean mist

Tangerine

Lime

Maroon

Correct Answer : Lime

Yellow and green color mix make a Lime color.

The three primary colors in additive mixing are red, green, and blue. In the absence of color or, when no colors are showing, the result is black. If all three primary colors are showing, the result is white. When red and green combine, the result is yellow. When red and blue combine, the result is magenta. When blue and green combine, the result is cyan.

10 .

What does airbag, used for safety of car driver, contain?

Sodium peroxide

Sodium nitrite

Sodium bicarbonate

Sodium azide

Correct Answer : Sodium azide

Sodium azide is used in airbag, used for safety of car driver. Under room temperature, sodium azide is a stable compound. However, when heated by an impulse it disintegrates to produce sodium and nitrogen.
