A 8000kg engine pulls a train of 5 wagons, each of 2000kg along a horizontal track.if the engine exerts a force of 40000N and the track offers a friction force of 5000N, then calculate.a)the net accelerating forceb)the acceleration of the trainc)the force of wagon 1 on wagon 2. |
|
Answer» Mass of the engine = 8000 kg Mass of each wagon = 2000 kg, Np. of wagons = 5 Total mass of train = 8000+2000×5= 18000 kg Force, F = 40000 N Track resistance , R = 5000 N Total accelerating force = F −R =40000−5000=35000 N Let acceleration = x m/s² Acceleration , = Accelerating force / mass x=35000/18000= 35/18=1.94 m/s² FRICTIONAL resistance of 4 wagons = 5000×(2000×4)/18000 =2222 .22 N Accelerating force on 4 wagons =2000×4×1.944 =15552 N Hence total force exertred by wagon on wagon 2= Accelerating force +Frictional resistance =2222 .22 +15552=17774.22 N Total force REQUIRED to produce acc hope it works plz brainlist me plzzzzzzzzzzzzzz |

An incompressible liquid of density riscontained in a vessel of uniform cross-sectional area A. If the atmo-spheric pressure is p, then the fore acting on a horizontal plane of area a situated at a depth d in liquid is givenby:(1) ap+apgh(2) P÷a +Pgd÷a(3) p+pgd÷ a(4) A(Pgd +p) |
|
Answer» <P>Answer: In an incompressible liquid, Pressure increase with increase in DEPTH. Hence force acting on horizontal plane of area a at depth d is given by, Force = Pa, where p is pressure acting on horizontal plane and a is area of plane. Pressure of incompressible liquid P acting along horizontal plane is GREATER than atmospheric pressure by ρgd ,where ρ is density of given liquid, g is acceleration due to gravity and d is depth. P=p+ρgd Hence Force= (p+ρgd)a Explanation: the correct OPTION is d |

इस अभिक्रिया का प्रेक्षण तीव्र बुदबुदाहट के साथ कार्बन डाइऑक्साइड निष्काषित होती हैplizz questions the answer |
|
Answer» Answer: कार्बन डाइआक्साइड (अंग्रेजी:CARBON DIOXIDE; रासायनिक सूत्र CO2), एक रंगहीन तथा गन्धहीन गैस है जो पृथ्वी पर जीवन के लिये अत्यावश्यक है। धरती पर यह प्राकृतिक रूप से पायी जाती है। धरती के वायुमण्डल में यह गैस आयतन के हिसाब से लगभग 0.03 प्रतिशत होती है। कार्बन डाईऑक्साइड कार्बन डाइआक्साइड का निर्माण आक्सीजन के दो परमाणु तथा कार्बन के एक परमाणु से मिलकर हुआ है। सामान्य तापमान तथा दबाव पर यह गैसीय अवस्था में रहती है। वायुमंडल में यह गैस 0.03% से 0.04% तक पाई जाती है, परन्तु मौसम में परिवर्तन के साथ वायु में इसकी सान्द्रता भी थोड़ी परिवर्तित होती रहती है। यह एक ग्रीनहाउस गैस है, क्योंकि सूर्य से आने वाली किरणों को तो यह पृथ्वी के धरातल पर पहुंचने देती है परन्तु पृथ्वी की गर्मी जब वापस अंतरिक्ष में जाना चाहती है तो यह उसे रोकती है।

Why life is exists on the earth but not on the planets such as venus and marsthese question in short qithin the limit of 40 to 50 words directed(2marks each) |
|
Answer» Answer: Both Venus and Mars have captured the human imagination during the twentieth century as possible abodes of life. Venus had long enchanted humans—all the more so after astronomers realized it was shrouded in a mysterious CLOAK of clouds permanently hiding the surface from view. It was also the closest planet to Earth, with nearly the same size and surface gravity. These attributes brought myriad speculations about the nature of Venus, its climate, and the possibility of life existing there in some form. Mars also harbored interest as a place where life had or might still exist. Seasonal changes on Mars were interpreted as due to the possible spread and retreat of ice caps and lichen-like vegetation. A core element of this belief rested with the CLIMATOLOGY of these two planets, as observed by astronomers, but these ideas were significantly altered, if not dashed during the space age. Missions to Venus and Mars revealed strikingly different worlds. The high TEMPERATURES and pressures found on Venus supported a “runaway greenhouse theory,” and Mars harbored an apparently lifeless landscape similar to the surface of the Moon. While hopes for Venus as an abode of life ended, the search for evidence of past life on Mars, possibly MICROBIAL, remains a central theme in space EXPLORATION. This survey explores the evolution of thinking about the climates of Venus and Mars as life-support systems, in comparison to Earth. Please follow me and like my answer.

Praveen took lead nitrate solution in a test tube and added sodium chloride solution toit. How will he prove that the reaction satisfies the law of conservation of mass? |
|
Answer» Answer: The residue left on evaporation will mostly be a mixture of three salts.The two definite ones are lead CHLORIDE and sodium NITRATE formed by the double displacement between sodium chloride and lead nitrate.2NaCl (aq) + PB(NO3)2 (aq) ——→ PbCl2 (s) + 2NaNO3 (aq)The THIRD constituent will be either the unreacted NaCl or Pb(NO3)2 that is present in excess of the 2:1 molar ratio in which these two salts react as per the above equation.But if NaCl and Pb(NO3)2 are taken in the exact 2:1 molar ratio in the test tube with sufficient water, the contents on evaporation are expected to yield, at least theoretically, a solid mixture having only NANO3 and PbCl2, in the 2:1 molar ratio. There should not be any unreacted NaCl or Pb(NO3)2 as a third constituent. |

Answer» An equation for the reaction of: a) iron with steam When a metal REACTS with steam then the products formed are metal oxide and hydrogen GAS. Metal + steam Metal oxide + Hydrogen When red hot iron reacts with steam to form iron(11,111) oxide and hydrogen. Fe304 (s) 3Fe(s) + 4H2O(g) steam + 4H2(g) B) calcium with water: When a metal reacts with water( cold water or hot water) then the products formed are metal hydroxide and hydrogen gas. Metal hydroxide + Metal + steam Hydrogen Calcium reacts with cold water to form calcium hydroxide and hydrogen gas: Ca(s)+ 2H2O(1) ----- H2(g) Ca(OH)2(aq) + c) potassium with water. Potassium reacts violently with cold water to form potassium hydroxide and hydrogen gas: 2K(s)+ 2H2O(1) --------> 2KOH(aq) + H2(g) + HEAT.

Topare placed in the air. Which blade is shriller?c) Both the ladies have same shrillnessthe enement to entif pitch of sound wo blades of length 20 cm and 25.d) There is no relation between shrillness and length of the blade. |
|
Answer» Answer: Amplitude and Overtones Present There are 3 properties of sound, based on which we can distinguish one sound-note from the other. They are Loudness, pitch(or shrillness) and Timbre. Loudness of a sound depends on the Amplitude of the sound-wave. Greater the amplitude, louder is the sound. Pitch or shrillness depends on the FREQUENCY. Greater the frequency, shriller is the sound. Quality or Timbre depends on the overtones present in the sound, along with the fundamental note and their amplitudes. Timbre is the property by which two SOUNDS may appear DIFFERENT even if they are EQUALLY loud and SHRILL. |
