What are the limitations of Bernoulli\'s theorem |
| Answer» Limitations of Bernoulli\'s equation are:(i) The Bernoulli\'s equation is derived by assuming that there is no loss of mechanical energy i.e. sum of pressure energy, potential energy and kinetic energy is constant. But when fluid is in motion, a part of mechanical energy is converted into heat energy.(ii) The Bernoulli\'s equation is derived by assuming that liquid is non-viscous. But actually none of the liquids is non-viscous.(iii)The Bernoulli\'s equation is derived by assuming that velocity of every fluid particle across any cross-section of pipe is same. But the particles of central layer have maximum velocity and velocity decreases towards the walls of pipe. | |

What is the difference between oscillation and shm |
| Answer» There is no significant difference between oscillations and vibrations. ... Simple harmonic motion is the simplest form of oscillatory motion.

What is Heisenberg principle |
| Answer» The Heisenberg Uncertainty Principle states that we cannot determine the position and momentum of a microscopic particle simultaneously which means that if Momentum is certain then the position becomes uncertain and if the position is certain then the momentum becomes uncertain...The product of the uncertainty in momentum and position is always less than or equal to h/4π. | |

Why we take accelaretion due to gravity ? |
| Answer» When the object falls towards the earth due to the earth\'s gravitational force, it something we call as free fall of the object. ... The acceleration due to gravity is the acceleration produced in the freely falling body due to the influence of the gravitational pull of the earth. So it is necessary to consider acceleration of gravity also | |
| 1631. |
Why in centripetal force , work done is zero? |
| Answer» We know that Work, W = F. S Cos θ. As the centripetal force is perpendicular to the dispalcement = 90 0 ⇒ Cos θ = Cos 90 0 ⇒ Cos θ = 0 ⇒ W = F. S Cos θ = 0 ⇒ W = 0<br>Because centrifugal force is also acting just opposite to it | |

Can anybody make me understand what is conservative force |
| Answer» Not easy for me ??<br>Conservative forces are those for which work done depends only on initial and final points.Example- Gravitational force, Electrostatic force.Non-Conservative forces are those where the work done or the kinetic energy did depend on other factors such as the velocity or the particular path taken by the object.Example- Frictional force.<br>Very easy topic...dear | |

What is angular displacement |
| Answer» Angular Displacement Formula: The angular displacement is defined as the angle through which an object moves on a circular path. It is the angle, in radians, between the initial and final positions.(θf - θi) = angular displacementθ = s/rθ = angular displacement through which movement has occurreds = distance travelledr = radius of the circle<br>Nothing | |

explain elastic collision in detail pls dont copy from google |
| Answer» ELASTIC COLLISION: - (1.) If in a collision, kinetic energy after Collisons is equal to kinetic energy before collisions is said to be perfectly elastic. (2.) Coefficient of restitution, e = 1. (3.) (KE)final = (KE)initial (4.) Eaxmples :- a.) Collision between atomic particles. b.) Bouncing of ball with same velocity after the collision with earth. Hope this will help you........<br>thanks<br>Elastic collision in simple words...is collision which takes place without loss of kinetic energy...momentum is conserved ....elastic energy is conserved and kE is conserved | |

what is momentum and its unit |
| Answer» We can define momentum as the quantity of motion of the body. It is measured by mass × velocity , as momentum depends upon velocity, and it depends on the direction of the motion of the body as well.Momentum = Mass × Velocityp = mvThe S.I. unit of momentum is kilogram metre per second (kg ms-1) | |

Streamline flow |
| Answer» Streamline flow in fluids is defined as the flow in which the fluids flow in parallel layers such that there is no disruption or intermixing of the layers and at a given point, the velocity of each fluid particle passing by remains constant with time. Here, at low fluid velocities, there are no turbulent velocity fluctuations and the fluid tends to flow without lateral mixing. Here, the motion of particles of the fluid follows a particular order with respect to the particles moving in a straight line parallel to the wall of the pipe such that the adjacent layers slide past each other like playing cards.<br>flow of a fluid in which its velocity at any point is constant or varies in a regular manner. It can be represented by streamlines. It\'s other name is laminar flow. | |
