Apparent magnitude was first documented by the Greek scientist and mathematician Hipparchus. In about 130 B.C., Hipparchus recorded how bright the stars were to each other when viewing them in the night sky. Hipparchus gave the brightest stars in the sky a value of '1'. The next brightest ...
What is the magnitude of the gravitational force due to the sphere on a particle of mass 2.2 kg located at a distance of: (a) 8.5 m and (b) 0.82 m from the center of the Find the density of the earth if its mass is 6 times 10^3 kg and radius is...
The magnitude of complex power i.e. |S| = (P2+ Q2)½is known as theapparent powerand its unit is volt-ampere. This quantity is a product of absolute value of voltage andcurrent. Again absolute value of current is directly related to heating effect as perJoule’s law of heating. Hen...
axial diffusivity, while the diffusivities in the two minor axes are often averaged to produce a measure of radial diffusivity. It is also possible to calculate the magnitude of diffusion, reflected by the mean diffusivity, and the degree of anisotropy, which is a measure of tissue organi...
In this paper, it is shown that the theoretical “ratio” between the moment magnitude Mw and Me and therefore Mw and ML for an individual earthquake can be determined directly from the earthquake fault aspect ratio β using the equation Mw/Me = p where p = 2/3 (1 + β...
