Answer 1

hope it helps u.if any query plz let me know

Answer 2

Answer: The correct answer is $\lambda = 10^{-35 } m}$.

Explanation:

The expression for the wavelength in terms of mass and velocity is as follows;

$\lambda =\frac{h}{mv}$

Here, h is Planck's constant, m is the mass of the object and v is the speed of the object.

It is given in the problem that a 0.66 kg ball is moving with a speed of 100 m/s .

Put m= 0.66 kg, v= 100 m/s and $h=6.6\times 10^{-34} J s$ in the above expression.

$\lambda =\frac{6.6\times 10^{-34}}{(0.66)(100)}$

$\lambda = 10^{-35 } m}$

Therefore, the wavelength of the ball is $\lambda = 10^{-35 } m}$.
