GCSE Bitesize was launched in January 1998, covering seven subjects. For each subject, a one- or two-hour long TV programme would be broadcast overnight in the BBC Learning Zone block, and supporting material was available in books and on the BBC website. At the time, only around 9% of UK households had access to the internet at home.
Standard electrode potentials offer a quantitative measure of the power of a reducing agent, rather than the qualitative considerations of other reactive series. However, they are only valid for standard conditions: in particular, they only apply to reactions in aqueous solution. Even with this proviso, the electrode potentials of lithium and ...
For GCSE Science the old single-award ‘science’ and ‘additional science’ options are no longer available, being replaced with a double award ‘combined science’ option (graded on the scale 9–9 to 1–1 and equivalent to 2 GCSEs). Alternatively pupils can take separate qualifications in chemistry, biology and physics.
Combined Science results in two GCSEs. Those with GCSEs in Combined Science can progress to A Levels in all of the three natural science subjects. Prior to this, around 1996, Combined Science GCSEs were available as an alternative to three separate Sciences for many exam boards. Combined Science consists of either Higher Tier (HT) or Foundation ...
In Scotland, Highers and Advanced Highers replace GCSEs and A-levels respectively. The content of the qualifications is fairly similar. Since Scottish post-16 school students finish school a year earlier than their counterparts in the rest of the UK, the content of the first year of the physics degrees offered at most Scottish universities is similar to the second year of A-level physics.
Typically, a human's center of mass is detected with one of two methods: the reaction board method is a static analysis that involves the person lying down on that instrument, and use of their static equilibrium equation to find their center of mass; the segmentation method relies on a mathematical solution based on the physical principle that ...
In mechanics and physics, simple harmonic motion (sometimes abbreviated as SHM) is a special type of periodic motion an object experiences by means of a restoring force whose magnitude is directly proportional to the distance of the object from an equilibrium position and acts towards the equilibrium position.
A potential-flow solution exists for any value of the circulation and any value of the lift. One way to resolve this indeterminacy is to impose the Kutta condition, [109] [110] which is that, of all the possible solutions, the physically reasonable solution is the one in which the flow leaves the trailing edge smoothly. The streamline sketches ...
