Displacement: - The modification in position of a body in a particular direction is called as displacement. It is a vector function and its unit in SI system is meter.
Distance: The actual length of path traversed by a body in a sub interval of time is known as distance. It is the actual path travelled by an object between its final and initial positions. It is a scalar function and its unit in SI is meter. Displacement can be positive, zero or negative but distance is always positive. If a particle goes in a straight line without modification in its direction, the value of displacement is same to the distance travelled. Otherwise it is usually less than it. Thus, Displacement distance
Eddy current loss is proportional to the (A) Frequency. (B) Square of the frequency. (C) Cube of the frequency. (D) Square-root of the frequency.
"The volume of needed mass of gas at fixed pressure is directly proportional to the Kelvin's temperature of the gas".
A 10 kilogram mass rests on a horizontal frictionless surface. A horizontal force of 5 Newtons is applied to the mass. After the force has been applied for 1 second, the velocity

Q. State the law of conservation of electric charges? The entirety charge in an isolated system always remains constant. For instance Uranium ( 92 U 238 ) can decay by emittin
Imagine a car tire that contains 5.1 moles of air when at a gauge pressure of 2.1×105N/m2 (the pressure above atmospheric pressure) and a temperature of 27 °C. The temperature incr
Ques: Point out the direction of the current if any induced to flow in the loop by the changing magnetic field. (Describe is the loop as viewed from above.) Answer:
A bucket of water is suspended from a ?xed point by a rope. The bucket is set in motion and the system swings as a pendulum. Though, the bucket leaks and the water slowly ?ows
Screw gauge works on the rule of screw. It has a linear scale called as the main scale, and another scale called as the circular scale. The circular scale can be moved by a head sc
