They are made up of chains of Hydrogen and c) Carbon
Explanation:
(a):their malleability:
>iron making. iron worker heat the meat and hammer it to give them the desired shape.
> in the jewelry making process, like the gold or silver you wear are results due to the malleability of metal
(b):their ductility:
>for the making of high tension cable that connects different cities for transferring of electricity.
>for making wire gauze
(c):their ability to conduct electricity:
>for lighting up your house with light bulbs
>for using cooking stoves
>to make refrigerator work.
Answer:
the difference of electrical potential between two points
Explanation:
Answer:
photons
Explanation:
Where,
n is the number of photons
h is Plank's constant having value
c is the speed of light having value
is the wavelength of the light
Given that, wavelength = 514 nm = ![514\times 10^{-9}\ m](https://tex.z-dn.net/?f=514%5Ctimes%2010%5E%7B-9%7D%5C%20m)
Energy = 10.0 mJ = 0.01 J ( 1 mJ = 0.001 J )
Applying the values as:-
![\frac{19.878n}{10^{17}\times \:514}=0.01](https://tex.z-dn.net/?f=%5Cfrac%7B19.878n%7D%7B10%5E%7B17%7D%5Ctimes%20%5C%3A514%7D%3D0.01)
