Motion of an object in a straight line is called one dimensional motion. The location of a particle in one dimensional motion can be explained by only one variable (say x). For a particle rolling along a straight line (1-D motion) all the vector quantities like velocity, position, acceleration and displacement have only one non-zero element.
A medium is known as denser if the velocity of ray in that phase is fewer than the speed of the wave in other phase. In comparison to air velocity of sound is main in water,
Explain the Photoelectric Effect Atomic Models Heinrich Hertz first observed the photoelectric effect in 1887. He noticed that if a photon with enough energy is absorbed by an
what is the angle of incidence when the refracted and the reflected ray are parallel to one another? does this angle depend on the wavelength of light? Ans) The angle of inciden
Figure shows a simple model of spring-mass system. The mass is released from the rest with the springs un-stretched. It's downward acceleration is a=9.81 - 15.24y m/s 2 where y is
Here's what is given: A. There are three 1 meter sticks B. There are four weights: Weight #1 = 1kg Weight #2 = 1.2kg Weight #3 = 1.5kg Weight #4 = 2kg The sticks don't hav
