The following is a list of notable unsolved problems grouped into broad areas of physics. [1]Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result.
W/(m⋅K) L M T −3 Θ −1: intensive Thermal resistance R: Measure for the ease with which an object resists conduction of heat K/W L −2 M −1 T 3 Θ: extensive Thermal resistivity R λ: Measure for the ease with which a material resists conduction of heat K⋅m/W L −1 M −1 T 3 Θ: intensive Viscosity: η: The measure of the internal ...
The entrance examination has a time limit of one hour. 100 marks are allocated based on objective questions, in which the mark allocation is distributed between a variety of subjects. Biology questions carry 30 marks, Chemistry carries 25, Physics carries 20, English carries 15, and general knowledge carries 10.
Other qualifications include IGCSE which replaces SSC. GCE and GCSE O Level, IGCSE and GCE AS/A Level are managed by British examination boards of CIE of the Cambridge Assessment and/or Edexcel International of the Pearson PLC. Generally, 8–10 courses are selected by students at GCE O Levels and 3–5 at GCE A Levels.
