Answer:
0.99 pounds
2,000 oz
0.423 cups
Explanation:
In order to convert this units we need to look up their equivalences.
1 g equals 0,0022 pounds approximately
Then we need to cross-multiply:
450 g equals 0.99 pounds approximately
We can do the same calculation for the other 2 ingredients
1 g equals 16 oz
Then (125 g x 16 oz) / 1 oz = 2,000 oz (or 500 4 oz)
1 cup equals 236.59 ml
Then (100 ml x 1 cup)/ 236.59 = 0.423 cups
The scientist uses an accelerator and high energy electrons to study the particles inside the protons of a helium atom, the particles under study are quarks.
Quarks are the elementary and fundamental part of matter. In Helium nucleus when the high energy is bombarded to study the particles inside the proton it is obvious that the scientist is studying the quarks inside the proton. In a proton there are two up quarks and one down quark present.
Answer: a)
b)
c)
Explanation:
Electronic configuration represents the total number of electrons that a neutral element contains. We add all the superscripts to know the number of electrons in an atom.
The electrons are filled according to Afbau's rule in order of increasing energies and thus the electronic configuration:
a)
b)
c)
