A body of mass $$m =3.513\ kg$$ is moving along the x-axis with a speed of $$5.00{ ms }^{ -1 }$$. The magnitude of its momentum is recorded as :


ANSWER

$$17.6\ kg{ ms }^{ -1 }$$


SOLUTION
Momentum$$=mv=3.513\times 5.00=17.565\approx 17.57$$
$$\approx 17.6 kg m/s$$
(Since 5.00 contains  least no. of significant figures i.e. 3)

The accuracy of measurement also lies in the way the result is expressed. The number of digits to which a value is to be expressed is one digit more than number of sure numbers. Rules do exist to deal with number of digits after an operation is carried out on the given values. The error can be minimised by many trials and using the correct methods and instruments.
If the length and breadth are measured as $$4.234$$ and $$1.05$$ m, the area of the rectangle is
  • A. $$4.4457 m^2$$
  • B. $$4.45 m^2$$
  • C. $$4.446 m^2$$
  • D. $$0.4446 m^2$$
