18 Year Wbcs Chapter-Wise General Science  Questions Paper (1999-2017)

1. All the planets are rotating around the sun around the sun around the sun, causing sun to be called a focus
......................
1. Doppler effect
2. Possession Law
3. Buyer's Law
Ans: 3. Buyer's Law

2. Is the earth rotating in its arc ..................... ..
1. South
2. East to the West
3. East-west
4. north of south
5. This one
Answer: 2. Explanation from the East:
The earth revolves around its axis in the west. This rotation makes the sun and they are moving from east to west.

3. Scale velocity ............ orbital velocity times
1.2
2.√3

The escape velocity is the escape velocity. Orbital velocity 2 times from the orbit of both orbits. The gravitational attraction of an object's massive body requires the minimum speed to "escape" for the object. Exclamation velocity of the Earth is approximately 40,270 km / h
4. If the strain is longitudinal, the modulus of elasticity is called, ...............................
1. Bulk modulus
2. Modesty of hardness
3. Young's Modulus
4. Density 5. This one

Explanation:
Young's modulus, also known as elastic modulus, is a mechanical property of linear elastic hard objects. It defines the relationship between pressure (unit area strength) and strain (proportional distortion) in a material

5. The amount of heat given to the system is used
2 ways ..................................
1. The Second Law of Thermomaniacs
2. Zeroth Law of Thermomaniacs
3. Thermomomanic Third Law
4. Thermodynamics First Law
5. This one

Answer and explain
Answer - 2. Thermodynamics explained the first law
:
Thermodynamics First Law - The amount of heat given on the system is used in two ways, first to increase the internal strength and to do the outside work.
6. Mercury is there ..................... .. specific heat
1.Low
2. High

7. ..................... Thermodynamics law is the result of human experience, under which thermal energy can be transformed 1. The second law of thermomaniacs
2. Zeroth Law of Thermomaniacs
3. Thermomomanic Third Law
4. Thermodynamics First Law
5. This one
Answer and explain
Answer - 1. Thermomaniacs Explanation Second Act:

The second law of thermodynamics is the result of human experience, under which thermal power can be converted to mechanical energy
8. Linear growth means ..................
1. Volume Extension
2. Area Extension
3. Length Expansion
4. Extension in width
5. This one
Answer and explain
Answer - 3. Expansion in length interpretation
:
Instead of changing the volume of the linear increment (the volume expansion), one dimension (length) changes.
9. Expansion of the area .........................
1. Coupling
2. Linear expansion
3.Sopharyphic expansion
4. Artificial Expansion
5. This one

Answer and explain
Answer - 3. Explain the extent of the expansion
:
The expansion of the area is called space expansion
Regarding the change in the dimension of the field's temperature changes in the temperature of the thermal expansion multiplier.

10. A steel block of a volume ................ Mite 1.002 If the cubic meter stretches, the temperature increases to 50.
1.1 cubic meters
2.1 meters
3.1 centimeters
4.1 millimeter
5. This one
Answer: 1.1 cubic meters Explanation:

Change the volume of an element by the amount of certain fractions. For example, the steel block with a volume of 1 cubic meter can increase to 1.002 cubic meters when the temperature is 50 K
1. Which height is used for measuring and aviation? 1.Phonograph
2.Altimeter
3.Ammeter
4.Dynamometer

An altimeter or a height meter is an instrument which is used to measure the height of an object above a certain layer. Height measurement is called altimetry.
2. ................................................ .................................................. .................................................. .............
1.Radiometer
2.Sesimogrpah
3.Hydrometer

An instrument for measuring the luminous flux (power) of a radiometer or rotangnimeter electromagnetic radiation.
Generally, a radiometer is an infrared radiation detector or ultraviolet detector.
3. Dynamo conversion ........................
.................................
1. Sound waves, mechanical strength
2. Electrical power, mechanical strength
3. Personal power, electric power
4. Personal power, sound power
5. This one
Answer and explain
Answer - 3. Personal power, electrical energy Explanation:
A dynamo is an instrument that transforms the mechanical energy into electrical energy
4. Which of the below measure the amount of heat
?
1.Periscope
2.Barometer
3.Chronometer

A calorimeter is an object that measures the calorimeter, or the temperature of the chemical reactions, or heat changes with the physical changes.
