What is motional emf? Factors on which it depends & expression for motional emf

Image
MOTIONAL EMF : The emf actuated across the closures of a conductor because of its movement in a magnetic field is called motional emf. PFACTORS ON WHICH THE  MOTIONAL EMF DEPENDS: 1. Uniform magnetic field (B) 2. Velocity of the conductor moving in the U-moulded leading rails.(v) 3. Length of the conductor. (L) DERIVE AN EXPRESSION FOR THE MOTIONAL EMF INDUCED IN A CONDUCTOR  DESCRIPTION: Conductor PQ of length L is allowed to continue on a U-moulded leading rails. (Here the slidable conductor PQ is moved outwards with a speed v).When the conductor moved outwards the space of the rectangular circle increments and consequently the attractive transition connected with the shut circle increments. Thus,the magnetic flux linked with the closed-loop increases. An emf is set up across the conductor PQ due to which an initiated current stream in the anticlockwis e course (as displayed in the image).According to Faraday's law of electromagnetic induction the emf incited is - BLv...

What are the factors that affect the projectile motion?

Image
  FACTORS THAT AFFECT THE FLIGHT OF A PROJECTILE: Projection point(angle) : The article is leaned at a point to the vertical or flat (horizontal) (close to the earth) The mass of the article: The flight condition incorporates no data about the item size, shape, or mass. Dispatch speed:  Maximum stature (height) changes as the square of the dispatch speed (launch velocity). Multiplying the dispatch speed creates multiple times the greatest stature. Gravitational speed increase:  It is the rate at which an article's speed is evolving. The change can be the means by which quick the article is moving,a bearing change or both. Air opposition:  Effects will be disregarded. The drag of the air: Drag relies upon air thickness and the square of the velocity.If the drag is overlooked, the flight relies upon starting speed and speed increase due to gravity(near the earth).
