5 bibes are required to fill a petrol tank in a hours 20 minuts. How long will it take for 8 pipes of the some type are used? |
|
Answer» We can SEE that if the NUMBER of pipes increases, the time decreases. So, inverse proportion is in action here. So, 5pipes=1hr 20 min=80 min[1hr=60min] 1 pipe=5×80 mins. So, 8pipes=(5×80)÷8mins=50mins So, 8 pipes will fill the tank in 50 mins. or 5/6 hr. Please mark the ANSWER as brainliest if you think this answer deserves it. |

a wire of length L and cross-sectional area has resistance A is divided from the middle. find the resistance and the resistivity of the new length formed. give reason in support of your answer. |
|
Answer» The total amount of resistance to charge FLOW within a wire of an electric circuit is affected by some clearly identifiable variables. The total LENGTH of the wires will affect the amount of resistance. The longer the wire, the more resistance that there will be. There is a direct relationship between the amount of resistance encountered by charge and the length of wire it must traverse. If resistance occurs as the result of collisions between charge carriers and the atoms of the wire, then there is likely to be more collisions in a longer wire. More collisions mean more resistance. The cross-sectional area of the wires will affect the amount of resistance. Wider wires have a greater cross-sectional area. The wider the wire, the less resistance that there will be to the flow of electric charge. When all other variables are the same, charge will flow at higher rates through wider wires with greater cross-sectional areas than through thinner wires. Another factor that affects the resistance to charge flow is the material that a wire is made of. Not all materials are created equal in terms of their conductive ability. Some materials are better conductors than others and offer less resistance to the flow of charge. Silver is one of the best conductors but is never used in wires of household circuits due to its cost. COPPER and aluminum are AMONG the LEAST expensive materials with suitable conducting ability to permit their use in wires of household circuits. |

The area of a square 1600 m find the area of a rectangle whose breadth os same as that of the square and length is 10 m more than its breadth. |
|
Answer» Given :
To find :
Step-by-step explanation: Area of square= 1600 m² [Given] We know that, Area of the square = side²Substituting the values in the above formula, we get, side² = 1600 side = √1600 side = 40 m Thus, the side of the square = 40 m It is given that lenght of the is 10 m greater than the side of the square. So, the length of rectangle = 40 + 10 The length of rectangle = 50 m Breadth of the rectangle as same as the side of the square = 40 cm. [Given] Now, We know that, Area of rectangle = length × breadthSubstituting the values in the above formula, we get, = 50 × 40 = 2,000. Therefore, The Area of the rectangle = 2,000 m². |
