What is the wavelength in picometers for an electron moving at 1,495 km ?

Wavelength = 486.51 pm

Explanation:

The expression for the deBroglie wavelength is:

Where,  

is the deBroglie wavelength  

h is Plank's constant having value

m is the mass of electron having value

v is the speed of electron.

Given that v = 1495 km/s (Corrected from source)

Also, 1 km = 1000 m

So, v = 1495000 m/s

Applying in the equation as:

Also, 1 m = 10¹² pm

So, Wavelength = 486.51 pm

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

i would say b

explanation:

but i think i would need more information than that
