In normal Newtonian physics, it is usually considered that the Moon revolves around the Earth. With a lower mass, the Moon is affected by the Earth’s gravity more than the Earth is affected by the Moon. The two bodies orbit around the barycenter, a point of gravitational equilibrium approximately 3/4 of the Earth’s radius from the center of the planet.

The motions of these celestial bodies depend on your point of reference, and the mass of the bodies. The Earth, Moon, Sun, and the other planets are traveling in eccentric paths around the center of the Milky Way Galaxy, which is itself moving relative to the other galaxies in the vicinity.

Using de Broglie's equation, λ = h/mv which would have a larger wavelength, a slow-moving proton or a fast-moving golf ball? Exp

Answer: Proton will have larger wavelength

Explanation:

$\lambda =\frac{h}{mv}$ (de-Broglie's equation)

$\lambda =\text{wavelenght of the particle}$

h= Planck constant

m= mass of the particle

v= velocity of the particle

As we can see from the de-Broglie's equation , that wavelength is inversely proportional to the product of mass into velocity of the object.

The wavelength of proton will be higher than that fast moving golf ball because mass of proton $(1.67 \times 10^{-24}g)$ is very small than that of the golf ball (45.93 g). Proton is moving at slow velocity and the golf ball is moving with fast velocity by which value of product of mass into velocity of proton will be lower than the value of product of mass into velocity of the golf ball which will result in larger value of wavelength of the proton.
