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
Briefly explain how elliptically and circularly polarized light is generated. Describe the process for realization of plane polarized light from elliptically polarized light.
a body is thrown horizontally with a velocity of u from the top of a tower. the displacement of the stone when the horizontal and vertical velocities are equal is
A charge q1 is 9.00um is at the origin, and a charge q2 is -4.00um is on the x- axis 0.30m from the origin. find the electric field strength at point P, which is on the y - axis 0.
The voltage drops across two components when connected in series across an a.c. supply are v1 =150sin 314.2t and v2 =90sin(314.2t -∏/5) volts respectively. Determine (a) the v
Ask A rugby player passes the ball 9.75 m across the field, where it is caught at the same height as it left his hand. At what angle was the ball thrown if its initial speed was 12
Unbalanced forces cause accelerations. In this case, the unbalanced force is directed opposite the book's motion and will cause it to slow down. To verify if the forces acting
Magnification is the ratio of size of image to the size of object. hence it is a dimensionless constant. It has no units. 1/m is not its unit.(1/m is the unit of power=DIOPTRE)
The velocity with which the group of waves travels is called as group velocity or the velocity with which a ray packet goes is called as group velocity
WE are estimating the spares requirement for a radar power supply. The power supply was designated with a mean life of 6500 hours. the standard deviation determined from testing is
