Q:

Which Arab scientist could be given the credit of christening the mathematical discipline of algorithm?

A) Al-Khwarizmi B) Ibn al -Haytham
C) Ibn Rushd D) Ibn Sina
 
Answer & Explanation Answer: A) Al-Khwarizmi

Explanation:

Muḥammad ibn Mūsā al-Khwārizmī, formerly Latinized as Algorithmi,was a Persianscholar who produced works in mathematics, astronomy, and geography under the patronage of the Caliph Al-Ma'mun of the Abbasid Caliphate.

He also developed the concept of the algorithm in mathematics, which is why some have called him the "grandfather of computer science".

Q:

A parallel-plate capacitor of capacitance C1is  made  using  two  gold  plates.  Another parallel-plate capacitor of capacitance C2is made  using  two  aluminium  plates  with same  plate  separation,  and  all  the  four plates  are  of  same  area.  If gand aPare respectively  the  electrical  resistivities  of gold and aluminium, then which one of the following relations is correct?

A) C1>C2 B) C2>C1
C) C1pa = C2pg D) C1 = C2
 
Answer & Explanation Answer: D) C1 = C2

Explanation:

C1= capacitance of gold plates

C2=   capacitance   of   aluminium plates

rg= Gold’s resistivity

ra= Aluminium’s resistivity

As the capacitance depends on the shape,  size  &  geometrical  placing of  the  conductors  &  the  medium between them, hence, the value of capacitance  will  be  independent  of resistivity. Therefore, C1= C2
