A students performs an experiment to determine the young’s modulus of a wire , exactly 2m long buy Searle’s method . In a particular reading ,the student measures the extension in the length of the wire to be 0.8 mm with an uncertainty of ±0.05 mm at a load of exactly 1.0 kg the student also measures the diameter of the wire to be 0.4mm with an uncertainty of ± 0.01mm. Take g = 10.0 m𝑠^(−2) . The young’s modulus obtained from the reading is A) (2.0 ±0.3) x 〖10〗^11 N𝑚^(−2) B) (2.0 ±0.2) x 〖10〗^11 N𝑚^(−2) C) (2.0 ±0.1) x 〖10〗^11 N𝑚^(−2) D) (2.0 ±0.05) x 〖10〗^11 N𝑚^(−2)

class 10 video  what ohm's law? Ohm’s Law states that the current flowing through a conductor is directly proportional to the potential difference applied across its ends, provided the temperature and other physical conditions remain unchanged. Mathematically it can be represented as, objective question based on electric current open this link for objective    https://nexttopperinstitute.blogspot.com/2020/07/class-10th-objective-questions-on.html   Class 10       HOW TO ORGANISM REPRODUCE Question. 1(i) What is fertilisation? Distinguish between external fertilisation and internal fertilisation. (ii) What is the site of fertilisation in human beings? Answer. (i) Fertilisation is defined as the fusion of a male gamete (sperm) with a female gamete (an ovum or egg) to form a zygote during sexual reproduction. (ii) The site of fertilisation in human beings is in the fallopian tube of female reproductive system. Question.2 Define th...
