Calculate the de broglie wavelength of a 143 g baseball traveling at 95 mph.

De-Broglie wavelength of the baseball is

Explanation:

It is given that,

Mass of the baseball, m = 143 g = 0.143 kg

Velocity of the baseball, v = 95 m/h

Converting m/h to m/s

1 m/h = 0.447 m/s

Velocity of the baseball, v = 95 m/h = 42.46 m/s

De-Broglie wavelength is given by :

h is Planck's constant

Hence, the De-Broglie wavelength of the baseball is                  

answer: option c. i.e. electric current flowing “downhill” from the negative electrode to the positive electrode in a battery

explanation:

the water analogy to the circuits define the pipes (water flows) to the electric current. now, we know that the electric current flows from the positive terminal to the circuit (as shown in the diagram attached).

hence, option c is the correct answer.
