Explain in brief the vertical circular motion. Hence derive the expressions for velocities at different positions. |
|
Answer» Vertical circular motion:A body spins in a vertical CIRCLE in such a way that its motion at different points is different from the motion of the body being assumed to be vertical circular motion.Consider an object of mass m, wrapped at ONE end in a stretchable string whirled in a vertical circle of radius r. DUE to the influence of gravitational FORCE on Earth (g = 9.8 m/s²), The object's velocity and stress vary due to earth gravity in maximum magnitude form at the lowest to the SMALLEST at the highest location. |

(12) A voltmeter of resistance 500 can measure a maximum voltage of 5V. How can it be made to measure a maximum voltage of 100 V? |
|
Answer» you add a resistor of 500 OHMS, you will be able to read 10 VOLTS actual as 5 volts measured. So to read 100 Volts actual as 5 volts measured, you NEED to add 10 x this as the total resistance value. So 1,000 x 10 = 10,000 ohms.28-Jun-2020 |

Difference between uniform motion and non- uniform motion |
|
Answer» motion is a type of motion that is characterized as the motion of an object wherein the object moves in a straight line and its velocity remains unchanged along that line, regardless of the duration of time, as it occupies EQUAL distances at equal time intervals.If a car’s speed is 10 m/s, it implies that in one SECOND the car covers 10 meters. The speed is unchanged in each second.Movement of the ceiling fan’s blades.Non-uniform motion is described as the motion of an object wherein the object moves at DIFFERENT speeds and does not cover the same distance at equal time intervals, regardless of the duration of the time interval.If in the FIRST two seconds, a car occupies 10 meters and in the next two seconds it covers15 meters.A train’s movement. |

1. Look at the activities listed below. Reason out whether or not work is done in the light of your understanding of the term 'work'. Suma is swimming in a pond. A donkey is carrying a load on its back. A wind-mill is lifting water from a well. A green plant is carrying out photosynthesis. An engine is pulling a train. Food grains are getting dried in the sun. A sailboat is moving due to wind energy. |
|
Answer» tion:Work is being done by Seema because she displaces the WATER by APPLYING the force.No work is being done by the donkey because the direction of force i.e the load is vertically downward and displacement is along the horizontal. If displacement and force are perpendiculars then no work is done.Work is done because the windmill is lifting the water i.e., it is changing the position of water.No work is done because there are no force and displacement.Work is done because the ENGINE is changing the position of the train.No work’ is done because there is no force and no displacement.Work is done because the force acting on the BOAT is moving it. |

Two charges of +10 – 6 C are located 1 cm apart. (a) What is the force on a charge +10 – 8 C halfway between them? (b) What is the force on a charge of –10 – 8 C at the same place? |
|
Answer» In both cases the net force is ZERO because the third charge is exactly in the middle between 2 equal CHARGES. In part (a), the 10-8 C charge is repelled equally to the right and left by the 2 positive charges, so the net force is zero. In part (b), the -10-8 C charge is ATTRACTED equally to the left and the right by the 2 positive charges, so the net force is zero. You can compute the net force in both cases using Coulomb's law and SEE that you get zero. |

Property of matter which is dependent of gravity is |
|
Answer» into the universe as it is, I understand that the matter is as it is, because the electromagnetic FIELD (even nuclear forces tend to be electromagnetic in high temperatures) and the gravitational field are as they are. On the other HAND, these fields are as they are because the matter is as it is.Electromagnetic fields results from the electric nature of the matter constituting blocks. They carry electric charge. Gravitational fields are closed associated with MASS. Electromagnetic forces are formally described by the VALUES of charges in presence. Gravitational forces are formally described by the values of the masses in presence.So, there is a property of the matter (electric charge) that we link to electromagnetic fields.Hence, what is the corresponding property of the matter, that we should associate with gravitational field?the fact that there are two types of charge, is EXCELLENT- It allows for information flow. There would be no life, if this was not possible.but we need energy storage. Is the mass, responsible for that? is this energy storage mechanism that demands that gravitational forces are always attractive? |

Answer» Given parametersMass of the engine (M) = 8000 kgNumber of wagons = 5MASS of the wagons (m) = 2000 kgForce exerted by the engine (F ) = 40000 NFrictional force offered by the track (Ff) = 5000 N(a) Net ACCELERATING force (Fa) = F – FfFa = 40000 N – 5000 NFa = 35000 N(b) Let us consider the acceleration of the train to be a m/s2Acceleration is the ratio of net acceleration force by mass, i.e.a = Fa/mWhere m is the mass of the train, it can be calculated as followsThe total mass of the train (m) = Mass of the engine + (Mass of the wagons × NUMBER of wagons)m = 8000 + (5 × 2000)m = 18000 kgAcceleration of the train (a) = 35000/18000a = 1.944m/s2(c) The external force is only applied to waggon 1 directly. On the last four waggons, the net force is equal to the force added to waggon 2 by waggon 1.Let us consider the acceleration of the wagons is aw35000 = 5M × awaw = 35000/5maw = 35000/(5 × 2000)aw = 3.5 m/s2Then the mass of the last four wagons can be considered as mwmw = 2000 × 4mw = 8000 kgNow let us calculate the net force on the last four wagonsF’ = mw× awF’ = 8000 × 3.5F’ = 28000 N∴ The force of wagon-1 on the wagon-2 is 28000Nhope helps... |

A bus decreases its speed from 72 kmph to 60 kmph in 5 s. Find the acceleration of the bus. |
|
Answer» 0.66m/s² is the required acceleration Explanation:According to the QUESTIONIT is given that ,Initial velocity ,u = 72km/hFinal velocity ,v = 60km/hTime taken,t = 5swe need to calculate the acceleration of the bus. Firstly we change the unit here Initial velocity ,u = 72×5/18 Initial velocity ,u = 4×5 Initial velocity ,u = 20m/sFinal velocity,v = 60×5/18Final velocity ,v = 16.66m/sas we KNOW that acceleration is defined as the RATE of change in velocity. a = v-u/twhere,a denote accelerationv denote final velocityu denote initial velocityt denote time takenSubstitute the value we get➻ a = 16.66-20/5➻ a = -3.34/5➻ a = -0.66m/s²here NEGATIVE sign show RETARDATION Hence, the acceleration of the car is 0.66m/s². |
