Answer:
Work done, W = 100 J
Explanation:
We have, Billy the friendly Robot uses 50 N of force to lift a box 2 meters in the air.
It is required to find the work done by Billy.
Work done by an object is given in terms of force and displacement. The formula used to find the work done is given by :

So, the work performed by Billy is 100 J.
1.Lithium has the greater ionization energy
2. Vanadium has a greater ionization energy
In every molecule of

there is 8 atoms of Carbon.
IF we have 3.7 moles of

to find the number of moles of Carbon, just multiply by 8
3.7 * 8 = 29.6 mol Carbon
A mole is most similar to Avogadro's number -
6.02 x 10^23
