Just as large distances are measured in AU, parsec or light year, atomic or nuclear distances are measured with the help of microscopic units.

Monjur Alahi

Just as large distances are measured in AU, parsec or light year, atomic or nuclear distances are measured with the help of microscopic units. Match the units given in column A with their corresponding SI unit given in column B.

Column A Column B
i. Angstrom (A) a. 10-15 m
ii. femtometre (fm) b. 10-10 m
c. 10-12 m

Two particles start from point (2, -1), one moving two units along the line x+ y = 1 and the other 5 units along the line x - 2y = 4, If the particle

Correct Answer - `(2-sqrt(2), -1+sqrt(2)) " and " (2+2sqrt(5), -1+sqrt(5))` Given lines intersect at P(2,-1). Slope of line x+y-1 = 0 is -1. `therefore "tan"theta = -1` `therefore "cos"theta = -(1)/(sqrt(2)),...

Energy produced in nuclear fusion is much larger than that produced in nuclear fission. Why is it difficult to use fusion to produce energy ?

Nuclear fusion involves the fusion of lighter nuclei to form a heavy nucleus which is accompanied by an enormous amount of energy (heat). Fusion reaction requires extremely high temperature typically of...
