Find the surface area of revolution formed by revolving the curve x = 4 - 2sin t , y = 2cos t from 0 ≤ t ≤ π 2 about the y -axis. => 8 π ( π - 1) square units or 8 π ( π + 1) square units or 0 or (8 π - 1) square units..

Find the volume of the solid of revolution formed by revolving the region bounded by f ( y ) = y - y 2 and the y -axis (0 ≤ y ≤ 1) about x -axis. [Use shell method.] => π 6 cubic units or 7 π 1 2 cubic units or π 1 2 cubic units or π 3 cubic units or 1 4 π 1 2 cubic u..

Find the volume of the solid of revolution formed by revolving the region bounded by f ( x ) = ln x , x -axis, x = 1 and x = e about y -axis. [Use shell method.] => 2 π ( e 2 - 1) cubic units or π ( e 2 - 1) cubic units or 2 π ( e 2 + 1) cubic units or π 2 ( e 2 + 1 ) cubic un..

Question: 'Operation flood' is related to: 1. Flood and disaster management 2. White revolution (Milk production) 3. Green revolution 4. Brown revolution Answer: ..

It is the time taken by the particle executing SHM, to complete one oscillation i.e., a to and fro motion. It will be equal to the time taken by the body to complete one revolution or the circle of referen..

One lunar month is the time in which the moon completes one revolution around the earth. Units of all other physical quantities can be derived from the basic units and hence are called "derived units". The following table shows the list of various physical quantities, derived formula and..

Find the EMF in a coil of 50 turns, each of area 80 cm 2 when making 1800 revolutions per minute in a uniform field of flux density 6 x 10 - 3 ..

Question: Give an example of a body moving with a uniform speed but variable velocity. Answer: A body moving along the circumference of a circle. e.g., Revolution of the earth around the sun..

Only when the speed of the circulating ion is less than 'c' the speed of light, we find the frequency of revolution to be independent of its speed. At higher speeds, the mass of the ion will increase and this changes the time period of the ion revolution. This results in the ..
