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
a small object is 10cm in front of a plane mirror if you stand behind the object 30cm from it and look at its image for what distance must you focus your eyes
Why diffraction can't occur if slit width is less than the wavelength of the light? Can you explain?
This is due to the surface tension of water. Because of the surface tension , the drop tends to have minimum possible surface area, and the shape which is possible with minimum su
What is intramodal dispersion in optical fibres? Intramodal dispersion (Δτ mat ) Intramodal dispersion is nothing although material dispersion. The velocity dissimilarity of
EXAMPLES: (i) A book lying on the table remains at rest until it is listed or pushed by exerting a force. (ii)A rolling ball on the ground comes to rest after covering some
What is Power? Power is how fast work is done or energy is used. Example: Remember that cheeseburger (~1/4 pound) I lifted up one meter to do one joule of work? If you now
The effects of open circuits: An open circuit is essentially a break in the circuit. An open circuit in a series circuit will prevent the flow of current through the circuit. W
If 3 particles of different mass located at different positions: 1- 1kg position : (0,0) 2- 2kg position: (0,5) 3- 3kg position : (-1,0) If a force of 2 N at 45 degrees is applie
A copper rod which is 1 centimetre in diameter carries a current of 5 amps. The current is distributed uniformly throughout the rod. The magnetic field half way between the axis
A 10 kilogram body initially moving with a velocity of 10 meters per second makes a head-on collision with a 15 kilogram body initially at rest. The two objects stick together
