Interesting facts about lion can anyone say |
|
Answer» Answer: LIONS are the only cats that live in groups. A GROUP, or pride, can be up to 30 lions, depending on how much food and water is available. Female lions are the main hunters. While they’re out LOOKING for food, the males guard the pride’s territory and their young. A lion’s roar can be HEARD up to eight kilometres away. Lions scent mark their territory, using their wee, to create a border. Explanation: Mark me as Brainlist plsss |

Derive a formula to calculate effective resistance of three resistors R1, R2 and R3 whenconnected in series combination. |
|
Answer» Answer: Hey Mate ♣♣♣ Here's Ur Answer ♣♣♣♣ 1)SERIES Connection Derivation: Let there be 3 resistance R1, R2, and R3 connected in series. A battery of V volts has been applied to the ends of this series COMBINATION. Now suppose the potential difference across the resistance R1 is V1, R2 is V2 and R3 is V3. ∴ V= V1+V2+V3 ...(1) Now, suppose the total resistance of the combination be R, and the CURRENT flowing through the whole circuit be I. So, applying Ohm's law to the whole circuit, we GET : V/I = R or V=IR ...(2) ∵ The same current is flowing through all three resistances, so by applying Ohm's law to three of them we will get V1 = IR1 V2= IR2 and V3= IR3 (3) Now, putting (3) and (2) in equation (1), we get IR = IR1 + IR2 + IR3 i.e IR = I ( R1 + R2 + R3 ) ⇒ R = R1 + R2 + R3 Hence its derived 2) Parallel Connection we show 3 resistors connected 'in parallel' with one another. In this case, the current flowing into P is divided among the 3 resistors i = i1 + i2 + i3 However, the potential difference across any resistors is the same, namely i1 R1 = i2 R2 = 13 R3 These equations can be thought of as determining the currents i1, i2, i3. Substituting, We have i = ( V/R1 + V/R2 + V/R3 ) = V / R or 1/R1 + 1/R2 + 1/R3 = 1 / R. Similarly, For n number of resistors connected in parallel, The Total Equivalent resistance = 1/R1 + 1/ R2 +...+ 1/Rn = 1 / R. Hope this helps U ✌✌✌✌✌✌✌✌ |

|
Answer» 1. When AIR is contaminated with unwanted particles or substances which plays a harmful impact on the Earth, it is known to be air pollution. These substances that contaminate the Earth's atmosphere are known as air pollutants. They are produced or emerged by industries, factories, forest fires, etc. __________________________________ 2. There are several causes for air to get polluted. They are →
__________________________________ 3. The process in which the infrared radiation of the sun is absorbed by the greenhouse gases and not reflected back into space is known as the greenhouse effect. So, a greenhouse is made up of glass and it is used to grow plants in it. The sun's radiation provides warmth to the plants and the air present within the greenhouse. The HEAT that is trapped inside the greenhouse can't escape out and it provides warmth which is necessary for the growth of plants. This is a similar case with the Earth's atmosphere. In the day time, the sun warms the Earth's atmosphere and during the night time when the Earth cools down, the heat is reflected back into the atmosphere. The heat is absorbed by the greenhouse gases in the atmosphere of the Earth during this process. This results in the surface of the Earth to be warmer and makes the survival of living beings possible on Earth. However, the increased levels of greenhouse gases leads to an increase in the temperature of the Earth which leads to global warming. __________________________________ |

11. Draw a labelled diagram of an electric motor. Explain its principle and working.What is the function of a split ring in an electric motor? |
|
Answer» Principle: An electric MOTOR is a rotating device that converts electrical energy to mechanical energy working. Working: Current in the coil ABCD enters from the source battery through conducting BRUSH X and flow back to the battery through brush Y. Notice that the current in the arm AB of the coil flows from A to B. In arm CD it flows from C to D that is opposite to the DIRECTION of current through arm AB on applying Fleming’s left hand rule for the direction of force on a current-carrying conductor in a magnetic field. We find that the force acting on arm AB pushes it downwards while the force acting on arm CD pushes it upwards. Thus the coil and the Axle O, mounted free to turn about an axis, rotate anti-clockwise at half rotation. Q makes contact with the brush X and P with brush Y. THEREFORE the current in the coil gets reversed and flows along the path DCBA. The reversal of current also reverses the direction of force acting on the two arms AB and CD. Thus the arm AB of the coil that was earlier pushed down, is now pushed up and the arm CD previously pushed up is pushed down. There is a continuous rotation of the coil and to the axle. Split RINGS in electric motors acts as a commutator. solution |
