|
Answer» Explanation: This phenomenon USUALLY occurs in mirrors. This phenomenon usually occurs in Lenses. Reflection can SIMPLY be DEFINED as the reflection of light when it strikes the medium on a plane. Refraction can be defined as the process of the shift of light when it PASSES through a medium leading to the bending of light. |

Answer» परिभाषा:- यदि किसी वस्तु की स्थिति में समय के साथ परिवर्तन हो रहा है, तो वस्तु की इस अवस्था को गति (Motion) कहते हैं। Explanation : उदाहरण:- रोड पर चलती कार, पानी में तैरती नाव, समुद्र में चलता जहाज, हवा या वायु में उड़ता वायुयान आदि। गति के प्रकार यह कई प्रकार की होती है, जो कि निम्न प्रकार से हैं- 1.रेखीय गति जब कोई वस्तु एक सीधी रेखा में चलती है, तो उसे रेखीय गति कहते हैैं। उदाहरण:- पेड़ से गिरता फल, चलती हुई कार, चलती हुई ट्रेन आदि। 2.एकसमान गति जब कोई वस्तु किसी निश्चित दिशा में समान समय में समान दूरी तय करती है, तो उसे एकसमान गति कहते हैं। उदाहरण:- यदि कोई वस्तु पहले घंटे में 10 किमी, दूसरे घंटे में 10 किमी तथा तीसरे घंटे में 10 किमी चले, तो उसकी गति एकसमान गति होगी। 3.असमान गति जब कोई वस्तु किसी निश्चित दिशा में समान समय में अलग-अलग दूरी तय करती है, तो उसे असमान गति कहते हैं। उदाहरण:- यदि कोई वस्तु पहले घंटे में 10 किमी, दूसरे घंटे में 15 किमी तथा तीसरे घंटे में 8 किमी चले, तो उसकी गति असमान गति होगी। 4.अनियमित गति जब कोई वस्तु चलती अवस्था में लगातार अपनी दिशा बदलती रहती है, तो ऐसी गति को अनियमित गति कहते हैं। उदाहरण:- फूलों पर मंडराती तितलियों की गति आदि। 5.वृत्तीय गति जब कोई गतिमान वस्तु वृत्तीय मार्ग पर चलती है, तो ऐसी गति को वृत्तीय गति कहते हैं। उदाहरण:- पृथ्वी की गति, लट्टू की गति आदि। 6.एकसमान वृत्तीय गति जब कोई गतिमान वस्तु वृत्तीय मार्ग पर समान समय में समान दूरी तय करती है, तो वस्तु की ऐसी गति को एकसमान वृत्तीय गति कहते हैं। उदाहरण:- सूर्य के चारों ओर पृथ्वी की गति। 7.दोलनीय गति यदि कोई वस्तु किसी निश्चित बिंदु से ऊपर-नीचे या दाएं-बाएं चलती है, तो ऐसी गति को दोलनीय गति कहते हैं। उदाहरण:- झूले की गति, सरल लोलक की गति आदि। Hope it helps |

An ocean-depth sounding device emits a signal 38 kHz in water whose average temperature is 4°C. The impulse is reflected from the ocean bed and returned to the same location 1.62 s after the signal is emitted. Calculate: (i) The depth of the water |
|
Answer» Explanation: The SPEED of sound in WATER depends on the water properties of temperature, salinity and pressure (directly related to the DEPTH). A typical speed of sound in water NEAR the OCEAN surface is about 1520 meters per second. That is more than 4 times faster than the speed of sound in air. The speed of sound in water increases with increasing water temperature, increasing salinity and increasing depth. Most of the change in sound speed in the surface ocean is due to changes in temperature. This is because the effect of salinity on sound speed is small and salinity changes in the open ocean are small. Near shore and in estuaries, where the salinity varies greatly, salinity can have a more significant effect on the speed of sound in water. As the depth increases, the pressure of the water has the largest effect on the speed of sound. |

On a winter day you inhale cold air at a temperature of 13^(@)C and at 0% humidity.The amount of air you inhale is 0.2kg per hour.Inside your body you warm and humidify the air you then exhale the air at a temperature of 37^(@)C and 100% relative humidity.At a temperature of 37^(@)C each kilogram of air at 100% relative humidity contains 0.04kg of water vapor.X kcal are carried out of your body by the air that passes through your lungs in one hour.Find the X .Take into account both the heat needed to warm the air at constant pressure and the heat needed to vaporize the moisture that the exhaled air carries out of your body.The specific heat of air at constant pressure is 0.25kcal/^(@)C the heat of vaporization of water at 37^(@)C is 600kcal/kg . |

Answer» Answer: The sound pressure levels (SPLs) of common infant humidifiers were determined to identify the likely sound exposure to infants and young children. This primary investigative research study was completed at a tertiary-level academic medical center otolaryngology and audiology laboratory. FIVE commercially available humidifiers were obtained from brick-and-mortar infant supply stores. Sound levels were measured at 20-, 100-, and 150-cm distances at all available humidifier settings. Two of 5 (40%) humidifiers tested had SPL readings greater than the recommended hospital infant nursery levels (50 dB) at distances up to 100 cm. In this PRELIMINARY study, it was demonstrated that humidifiers marketed for infant nurseries may produce appreciably high decibel levels. Further characterization of the EFFECT of humidifier design on SPLs and further elucidation of ambient sound levels associated with hearing risk are necessary before definitive conclusions and recommendations can be made. © American Academy of |
