1 dzień temu · The moment of inertia depends on how mass is distributed around an axis of rotation, and will vary depending on the chosen axis. For a point-like mass, the moment of inertia about some axis is given by , where is the distance of the point from the axis, and is the mass. For an extended rigid body, the moment of inertia is just the sum of all ...
1 dzień temu · In mathematics, sine and cosine are trigonometric functions of an angle. The sine and cosine of an acute angle are defined in the context of a right triangle: for the specified angle, its sine is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (the hypotenuse ), and the cosine is ...

The equation has critical point at v = v c, through which the solution should pass, so that the flow at a great distance is supersonic.The initial speed cannot be arbitrary, and must be quite definite (~10 km s −1).At a temperature 10 6 K, Eq. gives at a distance of 1 AU a speed of about 300 km s −1This is quite consistent with the slow solar wind.
2 godz. temu · The timestamp distance will be sufficient for both the meteorological and astronomical indicators’ observation given that they can be witnessed by everyone in the area. The Haversine equation presented below was used to compute the shortest distance between two points on an earth surface using latitude and longitude parameters.
2 godz. temu · In this section, we construct an essentially non-oscillatory backward-characteristics scheme to solve highly convective problems. To this end, given a two-dimensional bounded domain \(\varOmega \subset \mathbb {R}^{2}\) with Lipschitz boundary \(\varGamma \) and a time interval [0, T], we are interested in solving the following problem:
