1. The liquid/liquids used in the simple barometer is/are
A. water
B. mercury
C. alcohol
D. All of these
The liquid used in the simple barometer is mercury. Barometer is a scientific instrument for measuring the atmospheric pressure. Sudden rise or fall of this liquid in the barometer helps in indicating thunderstorm, etc.
2. Which one of the following pair is not correctly matched?
A. Manometer - Pressure
B. Carburetor - Internal combustion engine
C. Cardiograph - Heart movement
D. Seismometer - Curvature of surface
Pair (d) is not correctly matched because seismometer is the internal part of the seismograph, which may be a pendulum or a part mounted on a spring, however it is often used synonymously with 'seismograph'. It measures the motion of the ground caused by an earthquake, volcanic eruption, etc.
3. Which of the following is correctly matched?
A.
B.
C.
D.
Pair (a) is correctly matched.
Thermoresistor is an instrument which acts as an electronic thermometer. These are thermally sensitive resistors whose prime function is to exhibit a large, predictable and precise change in electrical resistance when subjected to a corresponding change in body temperature.
Pairs (b), (c) and (d) are incorrectly matched because capacitor is not a thermometer. It is charge storing device. Bipolar junction transistor is used as an amplifier but not a rectifier. Junction diode is used as rectifier but not as an amplifier.
4. Which one of the following is not correctly matched?
A.
B.
C.
D.
Pair (c) is not correctly matched because tacheometer is a type of surveying instrument designed for the rapid measurement of distances, elevations and directions. However, barometer is used to measure the pressure difference.
5. Which one of the following pair is not correctly matched?
A. Odometer - measuring instrument for distance covered by motor wheels
B. Ondometer - measuring instrument for frequency of electromagnetic waves
C. Audiometer - device for measuring sound intensity
D. Ammeter - measuring instrument for electric power
Pair (d) is not correctly matched because ammeter is an instrument to measure electric current. It can not be used for measuring electrical power in the circuit. To measure electrical power, wattmeter is used.
6. Match the following.
A.
B.
C.
D.
The correct matching is A-3, B-4, C-2, D-1.
Stethoscope is a medical instrument used for hearing the sound of someone's heart.
Sphygmomanometer is an instrument used for measuring the blood pressure of human body.
Caratometer or karatmeter is a scientific device which is internationally acclaimed for checking the purity of gold.
Luxmeter is a device for measuring the intensity of light, that hits or passes through a surface.
7.Statics is related to which of the following?
A. State of motion
B. State of rest
C. State of mind
D. Study of date
Statics is related to the state of rest. Statics is the branch of mechanics that deals with bodies at rest. State of motion refers to an object's velocity and direction. Study of date often referred to as "Chronology" or "Dating Methods".
8. Static science is associated with
A. dynamic situation
B. situation of rest
C. mental situation
D. data analyzing
Static science is a branch of mechanics associated with situation of rest. Static science examines the equilibrium of forces acting on objects to determine their stability and is crucial in designing structures, bridges and Mechanical systems.
9. A vehicle covers half the distance with uniform speed 
and the other half with uniform speed . The average speed of the vehicle is
A.
B.
C.
D.
10 .Who is the first person to define speed?
A. Galileo
B. Newton
C. Kepler
D. Ptolemy
E. None of the above/More than one of the above
A.
B.
C.
D.
Galileo is the first person who defined speed. He defined the speed considering distance covered per unit time. Newton propounded the law of motion to describe the motion of the bodies and object. Kepler gives the law of planetary motion.
11. What is the correct equation for finding the acceleration?
A.
B.
C.
D.
12. Two balls 
and are of 10 kg and 1 kg , respectively. They are dropped simultaneously from a height of 20 m . Which of the following is correct?
A. A will reach the ground first
B. B will reach the ground first
C. Both B and B will reach the ground at the same time
D. None of the above
13. From the distance-time graphs of two motorists A and A, it can be seen that
A. A travelled with uniform speed but A did not
B. A travelled faster than A throughout
C. A travelled faster than A throughout
D. A and A travelled with equal speed
Both 
and travelled with a uniform speed as their distance-time graphs are straight lines which indicates a constant speed.
The slope of distance-time graph represent, the speed of an object from the graph, it is clear that slope of is greater than that of slope of .
Hence, is moving faster than .
14. The variation of displacement d with time d in the case of a particle falling freely under gravity from rest is correctly shown in the graph.
A.
B.
C.
D.
15. A smooth plane inclined at an angle 
with the horizontal as shown in the given figure. A body starts from rest and slides down on the inclined surface. The time taken by the body to reach the bottom is
A.
B.
C.
D.
