In metallurgy, non-ferrous metals are metals or alloys that do not contain iron in appreciable amounts. Generally more costly than ferrous metals, non-ferrous metals are used because of desirable properties such as low weight, higher conductivity, non-magnetic property or resistance to corrosion
The Servant does not kill the child Oedipus as he was ordered to do because "He pitied the child" based on the Oedipus Rex story. The servant was ordered to kill the child because of the prophecy that predicted King Laius' death. The king already had attempted to hurt Oedipus by piercing Oedipus's ankle. However, the servant did not finish the job and he rather saved the baby Oedipus.
Answer:
Frequency = 
Wavenumber = 
Energy = 
Energy = 1.4579 eV
Energy = 
Explanation:
As we are given the wavelength = 850 nm
conversion used : 
So, wavelength is 
The relation between frequency and wavelength is shown below as:

Where, c is the speed of light having value = 
So, Frequency is:


Wavenumber is the reciprocal of wavelength.
So,


Also,

where, h is Plank's constant having value as 
So,


Also,

So,


Also,

So,


Answer:
I think true
Explanation:
Well I mean...we cant see the future. Certain things will be achieveable in different ganerations like going on mars
