Explanation:
This calculator will find the missing variable in the physics equation for force (F = M * a), when two of the variables are known.
Answer:
C4H8O4
Explanation:
Let (CH20)x
C=1*12.01=12.01 (12.01, 1.01, 16.00 Avg mass of elements)
H=2*1.01=2.01
O=1*16.00=16.00
12.01 + 2.01 + 16.00 = 30.03
120.12/30,03=4
==> (CH2O)4 = C4H8O4
Answer:
The three models describes the structure of an atom based on different views.
Explanation:
Plum pudding model described the atom of consisting of negatively charged electrons embedded in positively charged substrates; this was later proven to be false. The Bohr's model described the electrons in an atom to orbit round the nucleus at different energy, the closer it's to the nucleus, the lesser the energy it needs. The Rutherford model claims the the nucleus of the atom contains protons and neutrons which forms the mass of the atom, the electrons surrounds the nucleus and it forms the volume of the atom.
The heat of vaporization is when it changes phases from liquid to gas. When it is quite low, it means that it has weak attraction between the liquid particles
Thank you for posting your question here. You just provide a situation, I assume below are the questions:
<span>1. What is the current in the heating element?
</span>
<span>2.What is the resistance of the dryer's heating element at its operating temperature?
</span>
Below are the answers:
1. <span>P = V∙I </span>
<span>I = P/V = 4100 W / 240 V = 17.08 A
</span>
2. <span>Ohm's law: </span>
<span>V = R∙I
</span><span>R = V/I = 240 V / 17.083 A = 14.05 Ω</span>
