11. If the weight of an object is 60 kgs, what will be its weight on the moon? (N=Newton)

1. 60N
2. 600N
3. 100N
4. 10N

Option “4” is correct.
If the weight of an object is 60 N then weight on the moon = Weight of an object on earth/6 =60/6=10N
12. The side mirrors of vehicles are of which type of mirrors?

1. Convex
2. Concave
3. Plane
4. Inverted

Option “1” is correct.
The convex mirror produces an upright image of any object and offers a wide viewing area as compared to the plane mirror. The usage of this type of mirror can be perceived on the car rear-view mirror, side-view mirror and even the motorcycles.
13. UV rays coming from Sun, majorly causes which cancer?

1. Lungs cancer
2. Liver cancer
3. Mouth cancer
4. Skin cancer

Option “4” is correct.
Ultraviolet (UV) radiation from the sun or sunbeds is the main cause of skin cancer.
14. Which of the following is not a vector quantity?

1. Acceleration
2. Electric current
3. Force
4. Velocity

Option “2” is correct.
It may seem that current is a vector because it have a magnitude and a direction. But the thing is, a vector always obey the law of addition of vectors. Since current doesn’t obey it and it follows algebraic addition, current is a scalar.
15. The phenomena of raising the outer edge of the curved roads, above the inner edge to provide necessary centripetal force to the vehicles to take a safe turn is called _____.

1. Banking of roads
2. Cornering of roads
3. Elevation of roads
4. Tempering of roads

Option “1” is correct.
The phenomenon of raising outer edge of the curved road above the inner edge is to provide necessary centripetal force to the vehicles to take a safer turn and the curved road is called Banking of Roads.
16. For which of the following game, players must have the knowledge of Pascal’s law?

1. Climbing
2. Paragliding
3. Rafting
4. Scuba diving

Option “4” is correct.
Pascal’s principle states that “a change in the pressure of an enclosed incompressible fluid is conveyed undiminished to every part of the fluid and to the surfaces of its container.” For every 10m depth the pressure on the diver increases by 1 atm so at a depth of 10 meters under water, pressure is twice the atmospheric pressure at sea level. Thus, during Scuba diving players must have the knowledge of Pascal’s law.
17. What is the value of the Least Distance of Distinct vision (in cm) for a normal human being?

1. 2.5
2. 25
3. 58
4. 60

Option “2” is correct.
Least distance of distinct vision is defined as the minimum distance between the eye lens and the object to form a clear image. For a healthy human eye, the least distance of distinct vision is 25 cm, however it varies with age.
18. Who invented the Centigrade scale?

1. Anders Celsius
2. Daniel Gabriel Fahrenheit
3. William Thomson
4. Wright Brothers

Option “1” is correct.
In 1742, Swedish astronomer, Anders Celsius invented the Celsius(Centigrade) temperature scale, which was named after the inventor.
19. On which principle does the hydraulic lift works?

1. Newton’s law
2. Pascal’s law
3. Archimedes’s law
4. Joule’s law

Option “2” is correct.
Pascal’s Law states that pressure that is applied to an enclosed fluid is transmitted equally to all other points. A hydraulic pump is a water pump that uses the kinetic energy of flowing water to force a small fraction of that water to a reservoir at a higher level. The hydraulic lift works because of Pascal’s law. If force is put on(according to Pascal’s Law), that force should be entirely felt on all points throughout the liquid.
20. The coil wire in the electric room heater or electric cooking heater is called __________.

1. Circuit
2. Element
3. Filament
4. Cells

Option “2” is correct.
The coil wire is heating element in electric room heater or electric cooking heater to converts electricity into heat through the process of resistive or Joule heating. Electric current passing through the element encounters resistance, resulting in heating of the element.
