Answer:
Explanation:
It is given that,
The radius of the inflated balloon is 7 cm.
We need to find the volume of air inside the balloon in milliliters.
The balloon is in the shape of a sphere whose volume is given by :
Hence, the volume of the air inside the balloon is .
Line 1: straight horizontal line
Line 2: straight line at a slope
Line 3: exponential growth curve
Line 4: the topmost curve (the one that initially increases but then starts levels out)
The answer is:
1. 500g stainless steel cup

Answer:
oxygen molecule
Explanation:
I belive it is oxygen molecule
Explanation:
It is given that r = 0.283 nm. As 1 nm = .
Hence, 0.283 nm =
- Formula for coulombic energy is as follows.
where, e = C
=
=
- As 1 eV =
So, 1 J =
Hence, U =
= 8.9 eV
- Also, 1 J =
= kJ/mol
Therefore, U = kJ/mol
=
