Is nutrient, carbohydrate, calorie or fatty acid a substance needed for body growth |
|
Answer» Answer: A-Z HOME / ... / CARBOHYDRATES, PROTEINS, AND FATS Carbohydrates, Proteins, and Fats By Adrienne Youdim, MD, David Geffen School of Medicine at UCLA Last full review/revision Aug 2019| Content last modified Aug 2019 CLICK HERE FOR THE PROFESSIONAL VERSION Carbohydrates, proteins, and fats supply 90% of the dry weight of the diet and 100% of its energy. All three provide energy (measured in calories), but the amount of energy in 1 gram (1/28 ounce) differs: 4 calories in a gram of carbohydrate or protein 9 calories in a gram of fat These nutrients also differ in how quickly they supply energy. Carbohydrates are the quickest, and fats are the slowest. Carbohydrates, proteins, and fats are DIGESTED in the intestine, where they are broken down into their basic units: Carbohydrates into sugars Fats into fatty acids and glycerol The BODY uses these basic units to BUILD substances it needs for growth, maintenance, and activity (including other carbohydrates, proteins, and fats). |

Why a sound cannot be heard on the moon |
|
Answer» This is because you cannot hear any SOUNDS in near-empty regions of space. Sound travels through the vibration of atoms and MOLECULES in a medium (such as AIR or water). In space, where there is no air, sound has no way to TRAVEL. |

How can sound wave having different frequencies have the same speed in the same medium |
|
Answer» Answer: sound in same medium has its particles averagely of same size and averagely same distance APART from each other. Explaination: This doesn't happen like that only. Sound frequency in different medium VARIES. "all types of sounds have the same SPEED in the same medium" Why ? Because sound in same medium has its particles averagely of same size and averagely same distance apart from each other. when a sound travels, it collides these particles together at the same speed irrespective of the loudness or PITCH so they travels at the same speed.

Does the surface area of an object affect the rate of radiation emission? |
|
Answer» Answer:
The surface area of an object has a DIRECT impact on its absorption and radiation capabilities. The WIDER the surface area the faster the ENERGY loss capability will be. but the wider the surface area and its ability to DISSIPATE heat evenly may impact the radiative affect.

An object is dropped from rest at a height of 220m and simultaneously another object is dropped from rest at a height 180m. The difference in their heights after 4s if both the objects drop with same acceleration is |
|
Answer» Explanation: Initial DIFFERENCE in height Δh=150m−100m=50m Distance for each body with TIME is given by: s=ut+ 2 1
at 2
In the above question both the object are released from REST, so initial velocity is: u=0 Since the object are dropped at same time, so decrease in height is, s 1
=s 2
= 2 1
gt 2 =20 m Height of FIRST body after 2 s, h 1
=150−20=130 m Height of second body after 2 s, h 2
=100−20=80 m Difference in heights =50 m |

निम्नको परिभाषित कर,स्पष्ट कीजिए-(a) समभारिक(b) समस्थानिक(c) रेडियो एक्टिव पदार्थ का अर्ध आयु काल। |
|
Answer» (a) समभारिक ► समभारिक वे तत्व हैं, जिनके परमाणुओं के परमाणु द्रव्यमान तो समान होते हैं। लेकिन उनके परमाणु क्रमांक अलग-अलग होते हैं, ऐसे परमाणुओं को समभारिक कहा जाता है। हम जानते हैं कि किसी परमाणु में उपस्थित प्रोटॉनों की संख्या को ही उनका परमाणु क्रमांक माना जाता है, इसलिए यह कहा जा सकता है कि समभारिक परमाणु वाले तत्वों में प्रोटॉनों की संख्या तो अलग होती है लेकिन उन में कुल प्रोटॉन और न्यूट्रॉन का योग समान होता है, इसलिए उनका परमाणु भार भी समान होता है लेकिन उनमें उपस्थित प्रोटॉनों की संख्या अलग-अलग होने के कारण उनका परमाणु क्रमांक अलग-अलग होता है। इसलिए आवर्त सारणी में ऐसे तत्वों का स्थान अलग-अलग होता है तथा इनके रसायनिक गुण भी अलग-अलग होते हैं। उदाहरण के लिए कार्बन और नाइट्रोजन दोनों का परमाणु भार 40 होता है, लेकिन दोनों के परमाणु क्रमांक अलग-अलग है। कार्बन का परमाणु क्रमांक 6 जबकि नाइट्रोजन का 7 है। समान परमाणु भार होने के कारण दोनों समभारिक हैं। (B) समस्थानिक ► समस्थानिक वे तत्व होते हैं, जिनके परमाणुओं की संख्या तो सामान होती है, लेकिन उनका परमाणु भार अलग-अलग होता है। ऐसे तत्वों के परमाणु में प्रोटॉन तो समान होते हैं, लेकिन उनमें नयूट्रॉनों की संख्या अलग-अलग होती है। चूंकि प्रोटॉनों की संख्या को ही परमाणु क्रमांक माना जाता है, इस कारण उनकी परमाणु संख्या तो सामान रहती है, लेकिन उनका परमाणु द्रव्यमान अलग होता है। आवर्त सारणी में ऐसे तत्वों को एक ही स्थान पर रखा जाता है। उदाहरण के लिए कार्बन का परमाणु क्रमांक 6 और उसके तीन समस्थानिक है, जैसे कार्बन-12, कार्बन-13 और कार्बन-14। इन सभी का परमाणु द्रव्यमान 12, 13 और 14 होगा, क्योंकि कार्बन का परमाणु क्रमांक 6 है। इसका मतलब कार्बन के सभी परमाणु में 6 प्रोटॉन होते हैं और इनके में न्यूट्रॉन की संख्या कार्बन-12 में 6, कार्बन-13 में 7 और कार्बन-14 में 8 होगी। इस प्रकार ये कार्बन के समस्थानिक हुए। (C) रेडियो एक्टिव पदार्थ का अर्ध आयु काल ► रेडियोएक्टिव पदार्थ के अर्ध आयु काल से तात्पर्य उस काल से है, जब किसी रेडियोएक्टिव पदार्थ की कुल मात्रा का अपनी आधी मात्रा तक विघटित होने में जितना समय लगता है, उस समय को उस रेडियोएक्टिव पदार्थ का अर्थ आयु काल कहते हैं। अर्थात जिस कालावधि में एक रेडियो एक्टिव पदार्थ अपनी मात्रा का आधा रह जाता है, वह कालावधी उस रेडियोएक्टिव पदार्थ की अर्ध आयु काल कहलाती है। उदाहरण के लिए यदि किसी रेडियो एक्टिव पदार्थ का अर्थ आयु काल 100 दिन है, तो इसका तात्पर्य यह है कि 100 दिन में वह पदार्थ अपनी कुल मात्रा का आधा रह जाएगा। कुल 200 दिन में वह पदार्थ अपनी प्रारंभिक मात्रा का 3/4 विघटित हो जायेगा। ☼☼☼☼☼☼☼☼☼☼☼☼☼☼☼☼☼☼☼☼☼☼☼☼☼☼☼☼☼☼☼☼☼ |

How does sound from a sound producing body travel through air to reach of ear |
|
Answer» Answer: A vibrating body is a sound producing body , when a body vibrates it causes motion in the nearby PARTICLES and particles pass their energy(motion) to the nearby particles AFTERWARDS the moving particles strikesto our ear DRUMS causing HEAR sensation in ourears and thus sound is heard |

When an object starts its motion from rest, the velocity time relation becomes |
|
Answer»
velocity-TIME. The relation between velocity and time is a SIMPLE one during UNIFORMLY accelerated, straight-line motion. The longer the acceleration, the GREATER the change in velocity. Change in velocity is directly PROPORTIONAL to time when acceleration is constant.

a particle experiences constant acceleration for 20 second after starting moving from rest. if it travels a distance s1 in the first 10 second and distance s2 in the next 10 second. find the relation between s1 and s2. |
Answer» ANSWER:GIVEN
TO FIND:
EXPLANATION:
u = 0 a = a m/s² t = 10 s v = 0 + a(10) v = 10a m/s
After 10s the PARTICLE will have the velocity of v = at which is the final velocity for the first ten seconds and INITIAL velocity for the next ten seconds. u = at m/s a = a m/s² t = 10 s |

Given the minimum force applied in parallel to the liquid to move an object of mass 100 g in the microscopic area, the material coefficient of friction is 0.4 |
|
Answer» Given: Given the MINIMUM force applied in parallel to the liquid to move an object of mass 100 g in the MICROSCOPIC AREA, the material COEFFICIENT of friction is 0.4 To find: The minimum force applied. Solution: From given, we have, The mass of object = m = 100 g The coefficient of friction = μ = 0.4 As the minimum force applied in parallel to the liquid, so we have, θ = 0° we use the formula, f = μmg cos θ f = 0.4 × 100 × 9.8 × cos 0° f = 392 N Therefore, the minimum force applied is 392 N |
