The first 3 of 20 questions. Unlock the series for the rest, each with a solution.
Q1. Arrange the following media in the order of increasing speed of sound through them at ordinary temperatures: air, water, steel.
निम्नलिखित माध्यमों को सामान्य तापमानों पर उनके माध्यम से ध्वनि की बढ़ती चाल के क्रम में व्यवस्थित कीजिए: वायु, जल, इस्पात।
- A. steel < water < air / इस्पात < जल < वायु
- B. water < air < steel / जल < वायु < इस्पात
- C. air < water < steel / वायु < जल < इस्पात
- D. air < steel < water / वायु < इस्पात < जल
Solution
Sound travels slowest in gases and fastest in solids: air (~340 m/s) < water (~1480 m/s) < steel (~5000 m/s).
ध्वनि गैसों में सबसे धीमी और ठोसों में सबसे तेज़ चलती है: वायु (~340 m/s) < जल (~1480 m/s) < इस्पात (~5000 m/s)।
Q2. A progressive harmonic wave on a string is described by y = A sin(ωt − kx). Match List I with List II. List I: A. Speed of the wave; B. Maximum speed of a particle of the string; C. Maximum acceleration of a particle of the string; D. Wavelength of the wave. List II: 1. 2π/k; 2. ω/k; 3. Aω²; 4. Aω. Select the correct matching.
एक डोरी पर एक प्रगामी आवर्ती तरंग का वर्णन y = A sin(ωt − kx) द्वारा किया जाता है। सूची I को सूची II के साथ सुमेलित कीजिए। सूची I: A. तरंग की चाल; B. डोरी के किसी कण की अधिकतम चाल; C. डोरी के किसी कण का अधिकतम त्वरण; D. तरंग की तरंगदैर्ध्य। सूची II: 1. 2π/k; 2. ω/k; 3. Aω²; 4. Aω। सही सुमेलन चुनिए।
- A. A-1, B-4, C-3, D-2
- B. A-2, B-4, C-1, D-3
- C. A-2, B-4, C-3, D-1
- D. A-2, B-3, C-4, D-1
Solution
The wave speed is ω/k (A-2); the maximum particle velocity is Aω (B-4); the maximum particle acceleration is Aω² (C-3); and the wavelength is 2π/k (D-1).
तरंग की चाल ω/k है (A-2); अधिकतम कण वेग Aω है (B-4); अधिकतम कण त्वरण Aω² है (C-3); और तरंगदैर्ध्य 2π/k है (D-1)।
Q3. A tuning fork of frequency 256 Hz produces 4 beats per second with another fork. When a little wax is loaded on the second fork, the beat frequency falls to 2 per second. The original frequency of the second fork was:
256 Hz आवृत्ति का एक स्वरित्र द्विभुज किसी अन्य द्विभुज के साथ प्रति सेकंड 4 विस्पंद उत्पन्न करता है। जब दूसरे द्विभुज पर थोड़ा मोम लादा जाता है, तो विस्पंद आवृत्ति घटकर प्रति सेकंड 2 हो जाती है। दूसरे द्विभुज की मूल आवृत्ति थी:
- A. 260 Hz
- B. 264 Hz
- C. 252 Hz
- D. 248 Hz
Solution
The second fork is either 252 or 260 Hz. Loading lowers its frequency; since the beats decreased, it must have been above 256 Hz, i.e. 260 Hz (loading moved it towards 256).
दूसरा द्विभुज या तो 252 या 260 Hz है। लादने से इसकी आवृत्ति घटती है; चूँकि विस्पंद घट गए, अतः यह 256 Hz से ऊपर रहा होगा, अर्थात् 260 Hz (लादने से यह 256 की ओर स्थानांतरित हुआ)।
