The book answers the 26 most common questions people have about 'aqidah of Sunnis, according to Deobandis. Al-Muhannad 'ala al-Mufannad ( Arabic : المهند على المفند , lit. 'The Sword on the Disproved'), also known as al-Tasdiqat li-Daf' al-Talbisat ( Arabic : التصديقات لدفع التلبيسات , lit.
Group 2: Humanities and Social Sciences; Group 3: Sciences; Group 4: Mathematics; Group 5: Creative and Vocational (Professional and Creative) The certificate is awarded to candidates who pass in seven IGCSE subjects — two Group 1 subjects, one subject from each of Groups 2–5, and a seventh subject which can be selected from any Group.
Electrostatics is a branch of physics that studies slow-moving or stationary electric charges. Since classical times , it has been known that some materials, such as amber , attract lightweight particles after rubbing .
The Nobel Prize in physics was awarded to Dutch physicist Frits Zernike in 1953 for his development of phase contrast illumination which allows imaging of transparent samples. By using interference rather than absorption of light, extremely transparent samples, such as live mammalian cells, can be imaged without having to use staining techniques.
A ray diagram for a plane mirror. The incident light rays from the object create an apparent mirror image for the observer.. A plane mirror is made using some highly reflecting and polished surface such as a silver or aluminium surface in a process called silvering. [6]
Oxford, Cambridge and RSA Examinations [2] (OCR) is an examination board which sets examinations and awards qualifications (including GCSEs and A-levels). It is one of England, Wales and Northern Ireland's five main examination boards. OCR is based in Cambridge, with an office in Bourn, Coventry.
The remaining two half-lines in the two X s can be linked to each other in two ways, so that the total number of ways to form the diagram is 4 × 3 × 4 × 3 × 2 × 2, while the denominator is 4! × 4! × 2!. The total symmetry factor is 2, and the contribution of this diagram is divided by 2.
