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

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
