When a spherical body goes by a viscous fluid, it feels a viscous force. The value of the viscous force increases with the enhance in speed of the object falling under the function of its weight. As a result, the viscous force soon becomes the driving force and the object starts rolling with a constant speed, called as its terminal velocity. Let us now produce a relation for the terminal velocity, as an application of stokes' principle.
Q. Two slits 0.3 mm separately are illuminated by light of wavelength 4500 0A. The screen is placed at a distance 1m from the slits. Find the separation among the second bright fri
An astronomer observes that a molecule in a galaxy travelling toward Earth emits light with a wavelength of 514 nm. The astronomer identifies the molecule as one that actually
The Maximum displacement of a vibrating particle of medium from its mean position is known as amplitude.
A bicycle is supported so that it is stopped from falling sideways but can move forwards or backwards; its pedals are in their highest and lowest positions. A student crouches
The signal which has only two values. I.e. either a constant high value of voltage or zero value is known as digital voltage signal
Phase in sinusoidal functions or in waves has two different, but closely related, meanings. One is the initial angle of a sinusoidal function at its origin and is sometimes called
