What is the de Broglie wavelength (in meters) of a 45-g golf ball traveling at 72 m/s?
Cerrena [4.2K]

Answer: The de broglie wavelength is 2.037 \times 10^{-34} m.

Explanation:

Calculate  \lambda = \frac{h}{p}as follows.

          \lambda = \frac{h}{p}

where,

          h = plank's constant = 6.6 \times 10^{-34} m^{2} kg/s

         p = momentum = mass \times velocity

Putting the values in the formula as follows.

        \lambda = \frac{h}{mass \times velocity}

                               =  \frac {6.6 \times 10^{-34} m^{2} kg/s}{0.045 kg \times 72 m/s}                        

                               =  2.037 \times 10^{-34} m

Thus, the de broglie wavelength is 2.037 \times 10^{-34} m.

Water is initially present in a state where it's molecules are far apart. During a change of state it's molecules slow down whic
olga nikolaevna [1]

(A) gas to liquid is most likely to take place. This change from gas to liquid is the forming of water molecules. Gas particles have the most energy and therefore speed up the most, whereas solids have the least amount of energy and slow down. The intermediate step from gas to solid is a liquid. We call this process from gas to liquid condensation.
