Direction of the Angular Velocity Vector
In physics, the angular velocity is described as the rate of change of angular displacement and is a vector quantity (more precisely, a pseudovector) that exacts the angular speed (rotational speed) of an object and the axis about that the object is rotating. The SI unit of angular velocity is radians per second, while it may be measured within other units such as degrees per second and degrees per hour and etc.
A physics student performs a double-slit diffraction experiment on an optical bench, as shown in the figure below. The light from a helium-neon laser has a wavelength of 632.8
A motor has an output of 4.8kW, an efficiency of 80% and a power factor of 0.625 lagging when operated from a 240V, 50Hz supply. It is needed to improve the power factor to 0.9
A cooling drum consists of a (horizontally) rotating, large stainless steel cylinder. The cylinder has a diameter D and a width of W. The cooling at the inside of the drum is so ef
is it possible for the couple forces to be more than two?
You just need to use numerical methods to find temperature distribution in two or three dimensional plate; cylinder, sphere or you can model heat flow in any geometry with boundary
in what depends the charge that each material has? like glass positive; polystyrene negative; and ebonite negative; at the moment of charge a rod of those materials...?
Q. How is a galvanometer converted into (a) an ammeter and (b) a voltmeter? A galvanometer is transformed into an ammeter by connecting a low resistance in parallel with it. Th
REST: A body is said to be at rest if it does not alter its position with respect to its surroundings.
Q. An X-ray diffraction of a crystal gave a closest line at an angle of 6o27'. If the wavelength of X-ray is 0.58Ao, find the distance between the two cleavage planes. 2d Sinθ
Anti ferromagnetic materials such as chromium have a small but positive susceptibility. They cannot possess any magnetization is the absence of an applied field, in contrast to fer
