Engine of a car of mass 1500 kg, keeps car moving with constant velocity 5m/s. If frictional force is 1000 N, power of engin is ________ (A) 5 kW (B) 7.5 kW (C) 15 kW (D) 75 kW |
|
Answer» Power = 5kWExplanation:mass of car = 1500 kgvelocity = 5 m/sfrictional force = -1000 ( SINCE it APPLIES in opposite direction of MOTION)The force required to be produced by the engine has to be equal such that the net force acting on the car is 0 Nthus force of engine = 1000 NWork = Force × displacementWork = 1000 N × 5 m ( in 1 sec)Work = 5 kJPower = Work / timePower = 5kJ/ 1sPower = 5kWHOPE IT HELPS U!

A convex lens forms a real and inverted image of a needle at a distance of 50 cm from it Where is the needle placed in front of the convex lensif the image is equal to the size of the object? Also find the power of thelens. |
|
Answer» py Soul ❤Your Answer :The position of image should be at 2F, since the image is real and same size.It is given that the image of the NEEDLE is formed at a distance of 50 cm from the convex lens. THEREFORE, the needle is placed in front of the lens at a distance of 50 cm.Focal length :Object distance (u) = - 50 cmImage distance, (v) = 50 cmFocal length = fAccording to the lens formula,1/v - 1/u = 1/f1/f = 1/50 - 1/(-50)1/f = 1/50 + 1/501/f = 1/25f = 25 cm = 0.25 MPOWER of lens :p = 1 / f ( in meter)p = 1/0.25 = +4 DHope this will helps you ☺Note : Thanks to my answers n ho ske to follow VI kar LO ❤ |

Mention 2 structure & function of small intestine which add to the absorption capacity |
|
Answer» tion:The major portion of digestion and absorption of ingested food occurs in the small intestine (approximately 80% of all major nutrient is absorbed here) . Small intestine (SI) is about 21 feet in length. So actually PLENTY of space.But to INCREASE its capacity of absorption the wall of SI is thrown into a series of folds. These folds actually increases the surface area. These are called PLICAE.The innermost layer of the wall of SI, the mucosa contains 4 to 5 million microscopic finger like projections. These are VILLI. Each villi has in its core a capillary network to pick up absorbed nutrients.In ADDITION, each of the EPITHELIAL cells in the surface of the villi has a brush border of MICROVILLI. It further increases the capacity of absorption. |

Flow chart of chapter wind Storms and Cyclone |
|
Answer» tion:hlo mate here's your answer Winds - When the AIR moves in a flow in a particular direction it is CALLED wind.Air Exerts PressureWhy a tin can with hot water when cooled down with freshwater DISTORTS its shape?Figure 1 Air Exerts PressureAs fresh water is poured over the hot can the steam in the can condensers and CONVERTS into the water. This results in reducing the amount of air that is present in water. The pressure of the air outside the can becomes more than the pressure of the air inside the can. This results in compressing of the can. Therefore, it is proved that air exerts pressure.Flow of AirWhen the speed of the wind increases it lowers down the air pressure. Therefore, we can SAY that air flows from a region of high pressure to low pressure.i hope its help you mark as brainlist |

दौड़ते हुए वर्षा जल को चलता हुआ चलते हुए को रेंगता हुआ तथा रेंगते हुए को रोकना किसका मूल सिद्धांत है |
|
Answer» े पानी का संग्रहण (RAIN water harvesting)Explanation:वर्षा जल संचयन (आरडब्ल्यूएच) बारिश का संग्रह और भंडारण है, बजाय इसे बंद करने के। बारिश के पानी को छत की सतह से इकट्ठा किया जाता है और टंकी, सिस्टर्न, गहरे गड्ढे (अच्छी तरह से, शाफ्ट, या बोरहोल), जलभृत या एक जलाशय के साथ पुनर्निर्देशित किया जाता है।वर्षा जल संचयन प्रणाली में निम्नलिखित घटक होते हैं: कैचमेंट- पकड़े गए रेन वाटर को इकट्ठा करने और स्टोर करने के लिए उपयोग किया जाता है। कन्वेयन्स सिस्टम - इसका उपयोग कैचमेंट से रिचार्ज ज़ोन में काटा हुआ पानी पहुँचाने के लिए किया जाता है। फ्लश- इसका इस्तेमाल बारिश के पहले स्पैल को फ्लश करने के लिए किया जाता है। फ़िल्टर - एकत्रित रेनवॉटर को फ़िल्टर करने और प्रदूषकों को हटाने के लिए उपयोग किया जाता है। टैंक और रिचार्ज संरचनाएं: फ़िल्टर्ड पानी को संग्रहीत करने के लिए उपयोग किया जाता है जो उपयोग के लिए तैयार है। वर्षा जल संचयन की प्रक्रिया में कृत्रिम रूप से तैयार किए गए सिस्टम की सहायता से वर्षा जल का संग्रहण और संग्रहण शामिल है जो प्राकृतिक रूप से या मानव निर्मित जलग्रहण क्षेत्रों जैसे- छत, यौगिकों, चट्टान की सतह, पहाड़ी ढलानों, कृत्रिम रूप से मरम्मत की गई अशुद्ध या अर्ध-विकृतियों की वजह से चलती है। To KNOW moreRainwater harvesting should be encouraged - Brainly.in brainly.in/question/7646522 |
