The mass of a ball is $$1.76 kg$$. The mass of $$25$$ such balls is 


ANSWER

$$44.0 kg$$


SOLUTION
Mass of a ball   $$m = 1.76 \ kg$$
Number of balls   $$N = 25$$
So. mass of such 25 ball,   $$M = mN = 1.76\times 25 = 44.0 \ kg$$

The maximum number of significant digits in the mass and number of balls is 3. So, the answer will also have 3 significant digits.

Q1 Subjective Hard
 Einstein’s mass-energy relation emerging out of his famous theory of relativity relates mass (m) to energy (E) as $$E= mc^2$$, where c is the speed of light in vacuum. At the nuclear level, the magnitudes of energy are very small. The energy at nuclear level is usually measured in MeV, where $$1 MeV = 1.6 \times 10^{-13} J$$; the masses are measured in unified atomic mass unit (u) where, $$1 u = 67 \times 10^{-27} kg$$.
a)
Show that the energy equivalent of $$1 u$$ is $$931.5 MeV.$$
b)
A student writes the relation as $$1 u = 931.5 MeV$$. The teacher points out that the relation is dimensionally incorrect. Write the correct relation.
