The Bohr model of an atom is contradicted by

The uncertainty in position and velocity of a particle in motion are $1 \times 10^{-8} \ m$ and $6.627 \times 10^{-20} \ m/s$, respectively. The mass of the particle is $(h = 6.627 \times 10^{-34} \ J \cdot s)$

Write down Heisenberg's uncertainty principle.

$A$ golf ball has a mass of $40 \, g$ and a speed of $45 \, m/s$. If the speed can be measured within an accuracy of $2 \%$,calculate the uncertainty in the position.

The product of uncertainty in the position and uncertainty in the velocity of a particle is $5.79 \times 10^{-5} \ m^2 \ s^{-1}$. If the uncertainty in the position is $1 \ nm$, what is the uncertainty in the measurement of its velocity in $m \ s^{-1}$?

The mass of an electron is $9.11 \times 10^{-31} \ kg$,and the Planck constant is $6.626 \times 10^{-34} \ J \ s$. The uncertainty involved in the measurement of velocity within a distance of $0.1 \ \mathring{A}$ is:
