... 18c. Work . ... The concept of Work is closely related to that of energy. ... Suppose we lift a weight A of mass m a distance h (for height) from the floor to the table (Figure 1). ... That, however, is just the potential energy added to the weight! ... Energy is always preserved but--as seen in an earlier section--not always in a usable form. ... Because the trains are linked, when one goes up, the other descends, and by giving up its potential energy, it helps pull the other one upwards. ...

... The first of the equations defines the position of the spectral orders, m , in the raw image, while the second equation gives, for each order, the dispersion relation in one dimension. ... where the coefficients are computed using least squares techniques on a grid , i.e. sample number and line number of points located within the spectral orders of the image. These points in the grid are found automatically by an order--following algorithm, normally using the FLAT or STD image. ...

Next: Polarization efficiency: size/shape/orientation effects Up: Optical properties of cosmic Previous: The 2175? feature . To model the interstellar polarization one needs to calculate the forward-transmitted radiation for an ensemble of non-spherical aligned dust grains. ... Let non-polarized stellar radiation passes through a dusty cloud with a homogeneous magnetic field. ... The angle between the line of sight and the magnetic field is ( ). ... where the angle is connected with and ( ). ...

... The greater the distance, the smaller the parallax. ... That triangle has the same proportions as the much larger triangle ABC, and therefore, if the distance B'C to the thumb is 10 times the distance A'B' between the eyes, the distance AC to the far landmark is also 10 times the distance AB. ... The most distant objects our eyes can see are the stars, and they are very far indeed: light which moves at 300,000 kilometers (186,000 miles) per second, would take years, often many years, to reach them. ...

The following definitions of the observing conditions are common between Phase 1 preparation and Phase 2 preparation, as well as between Service Mode and Visitor Mode observations. ... There are additional Service Mode Policies and Service Mode Guidelines regarding the observing conditions. ... Seeing (Phase 1) and Image quality (Phase2) constraints . ... Moon . ...

... Though Flint knows the interface definitions (i.e. number, type and intent of each argument) of standard FORTRAN functions, it is desirable for users to build and use a file (or files) describing the interfaces to their own library. ... The format is: flint -o file .. ... While these interface definitions could be input along with normal source files, preceding the interface file with the -l (library) switch has the advantage that the source of this file does not appear in the listing file. ...

... SGML . The text/html content type . In this section, we begin the specification of HTML 4.0, starting with the contract between authors, documents, users, and user agents. ... These recommendations are not normative and conformance with this specification does not depend on their realization. ... An HTML document is an SGML document that meets the constraints of this specification. ... A user is a person who interacts with a user agent to view, hear, or otherwise use a rendered HTML document. ...

... There has been a heated public discussion in the past few years about whether our ninth planet is really deserving of the name. Since Pluto orbits a star, and is much less luminous, it certainly satisfies the definition we have above. The problem is actually not with Pluto, but with a very large number of other bodies in our Solar System which also satisfy this definition, but which are not called planets. Perhaps the most notable of these is Ceres, the largest asteroid. ... Planet . ...
