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
Nortan'sTheorem can be stated as follows: Any two-terminal active network having voltage source and resistances when viewed from its output terminals is equal to a constant-curren
Find amplitude of electric field ina parallel beam of light of intensity 2W/m2 Ans: Given that intensity I=power/area=2W/M2 by using this formula :intensity I=(Emax^2/2c mue not
