In other words, the tendency of undisturbed objects to stay at rest or to keep moving with the same velocity is called Inertia.
Q3. The time taken by a pendulum to complete one oscillation is called its?

(a) Maximum speed/ अधिकतम गति
(b) Average speed/ औसत गति
(c) Time period/ समय सीमा
(d) Time interval/ समय अंतराल
Sol. The time taken by a pendulum to complete one oscillation is called its Time Period.
Q4. If the weight of an object is 60 kgs, what will be its weight on the moon? (N=Newton)
यदि किसी वस्तु का वजन 60 किलोग्राम है, तो चंद्रमा पर इसका वजन क्या होगा? (N = न्यूटन)
(a) 60N
(b) 600N
(c) 100N
(d) 10N
Sol.
Given, Mass=60kg
Accleration in earth=10m/s^2
so,weight of the object in earth=60*10=600 N
weight of the object in moon = weight of the object in earth/6
weight of the object in moon = 600/6=100 N
Q5. The side mirrors of vehicles are of which type of mirrors?
वाहनों के किनारे दर्पण किस प्रकार के दर्पण हैं?
(a) Convex/ उत्तल
(b) Concave/ अवतल
(c) Plane/समतल
(d) Inverted/ उलटा
Sol. 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.
Q6. If the speed of an object moving along a straight line is constant, its motion is said to be _________.
यदि एक सीधी रेखा के साथ चलने वाली वस्तु की गति निरंतर है, तो इसकी गति को _________ कहा जाता है।
(a) Uniform /समान
(b)Periodic/ सामयिक
(c) Circular/परिपत्र
(d) Non-uniform/असमान
Sol. If the speed of an object moving along a straight line is constant, its motion is said to be uniform motion.
बल की ताकत आमतौर पर इसके __________ द्वारा व्यक्त की जाती है।
(a) Motion /गति
(b)Direction/ दिशा
(c)Interaction / इंटरेक्शन
(d)Magnitude/ मात्रा
Sol. The strength of a force is usually expressed by its Magnitude.
यदि वस्तुएं पीछे देखने वाले दर्पण में बड़ी और उलटी दिखाई देती है, तो इसमें किस प्रकार के दर्पण का उपयोग किया जाता है?
(a) Concave / अवतल
(b) Convex/ उत्तल
(c) Cylindrical / बेलनाकार
(d) Plane/समतल
Sol. Concave mirrors are used to provide a magnified and inverted image in rear view mirror.
साबुन का बुलबुला ______ के कारण गोलाकार आकार का होता है।
(a) Inertia / जड़त्व
(b) Pressure/ दबाव
(c) Surface tension / सतह तनाव
(d) Viscosity/ चिपचिपापन
Sol. The Surface tension of water provides the necessary wall tension for the formation of bubbles with soap water. The tendency to minimize that wall tension pulls the bubbles into spherical shape.
Q10. Speed of light is maximum in _____.
_____ में प्रकाश की गति अधिकतम है।
(a) Vacuum / वैक्यूम
(b) Solids/ ठोस
(c) Liquids / तरल पदार्थ
(d) Gases/ गैस
Sol. In absolute vacuum, there are no particles, no material medium, nothing. So, there is no reflection, refraction, diffraction, etc. That is why it travels the fastest in vacuum.
विद्युत प्रवाह की SI इकाई क्या है?
(a) Newton/न्यूटन
(b) Joule/ जौल
(c) Ampere/ एम्पेयर
(d) Watt/वाट
Sol. The SI unit for measuring an electric current is the ampere, which is the flow of electric charge across a surface at the rate of one coulomb per second. Electric current is measured using a device called an ammeter.
निम्नलिखित में से क्या ध्वनि की पिच निर्धारित करता है
(a) Amplitude / आयाम
(b) Frequency/ आवृत्ति
(c) Loudness / प्रबलता
(d) Wavelength/तरंगधैर्य
Sol. While frequency measures the cycle rate of the physical waveform, pitch is how high or low it sounds when you hear it. Pitch and Frequency are related to each other. A high pitch sound corresponds to a high frequency sound wave and a low pitch sound corresponds to a low frequency sound wave.
Q13. Which phenomena shows the particle nature of light?
कौन सी घटना प्रकाश की कणीय प्रकृति को दर्शाती है?
(a) Diffraction/ विवर्तन
(b) Interference/ व्यतिकरण
(c) Photoelectric effect/ प्रकाश विद्युत प्रभाव
(d) Polarisation / ध्रुवीकरण
Sol. The photoelectric effect is an phenomenon in which the emission of electrons occurs when a beam of light strikes a metal or a cathode surface. For emissions of electrons frequency of incident light is required to be greater than a minimum value called Threshold Frequency. Thus, show particle nature of light.
इलेक्ट्रिक मोटर _____ ऊर्जा को यांत्रिक ऊर्जा में परिवर्तित करता है
(a) Sound/ध्वनि
(b) Mechanical/ यांत्रिक
(c) Chemical/ रासायनिक
(d) Electrical/ विद्युतीय
Sol. An electric motor is an electrical machine that converts electrical energy into mechanical energy.
ऑप्टिकल फायर प्रकाश के निम्नलिखित में से किस सिद्धांत पर कार्य करता है?
(a) Reflection/परावर्तन
(b) Refraction/ अपवर्तन
(c) Diffraction / विवर्तन
(d) Total internal reflection/ कुल आंतरिक प्रतिबिंब
Sol. Optical fibre work on the principle of Total Internal Reflection of Light. In optical fibre, when light traveling in an optically dense medium hits a boundary at a steep angle (larger than the critical angle for the boundary), the light is completely reflected. This is called total internal reflection.
