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

$44.0 kg$

##### 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.
