3.11.1 Answering multiple-choice questions

Multiple-choice questions usually involve you in selecting the right answer from several possible responses. The questions are frequently short, and your answer requires no writing. However, finding the right answer may require you to do calculations on paper or, in some cases, check back through an extract of material very closely to see which is the correct of two possible answers. In the Sciences Good Study Guide there is a good example on pages 265–68, which shows the series of c

Isosceles Triangle Properties
In isosceles (and equilateral) triangles, a segment drawn from the vertex angle to the opposite side is the altitude, angle bisector and median. This video explains how isosceles triangle properties are used in many proofs and problems where the student must realize that, for example, an altitude is also a median or an angle bisector to find a missing side or angle.

Question 1

Envisioning Cyberspace: The Design of On-Line Communities
The development of the World Wide Web into an active, visual social environment poses unique opportunities for the design professions. Multi-user Domains, social meeting places in cyberspace, are mostly text-based virtual realities which use spatial references to set the stage for social interaction. Over the past year design students at the New Jersey Institute of Technology School of Architecture have investigated several text-based domains. In the course of their work, they envisioned and gra

4.5 How wide were the oceans?

Once evidence has been found to prove the existence of an ancient ocean, is it possible to calculate its maximum width? Palaeomagnetic studies can give geologists an idea of the palaeolatitude (N–S) of the ocean but not its palaeolongtitude (E–W), so depending on its orientation, an indication of how wide it was may not be possible. However, an approximate indication of how wide the former oceans were can be obtained by examining the fossil faunal assemblages that are present (e.g.

Model of Clouds during Hurricane Isabel, 2003 (WMS)
The NASA finite-volume General Circulation Model (fvGCM) is used to produce a high-resolution weather prediction system. This model has an increased accuracy of predicting the strength and location of hurricanes over other prediction methods. Several variables are predicted, including cloud cover and precipitable water in the atmosphere. Data from Hurricane Isabel was used to validate the fvGCM model.
