You haven't told us what any of those letters represents.
I'm going to assume that ...
-- ' P ' = power
-- ' I ' = circuit current
-- ' V ' = circuit voltage
-- ' E ' = energy
-- ' t ' = time.
Now I'm ready to answer the question that I just invented.
P = I / V
V = P x I
Both of these are false statements, and can't be used to calculate anything.
P = I x V is the correct equation to calculate electrical power.
<em>E = P x t</em> is the correct equation to calculate electrical energy.
Answer:
0.045 J
Explanation:
The work done on a charge moving through a potential difference is given by
where
W is the work done
q is the charge
is the potential difference
In this problem, we have
q = 0.0050 C is the charge
is the potential difference
Using the formula, we find the work done:
Answer:
Because there are other elements that get in touch with it. And over time with, evolution, erosion and temperature their particles tend to mix. So what once was very common became mixed over time.
C.
The kilogram SI unit is based off an original prototype that is kept in France. The prototype itself is based off the mass of water under special conditions for temperature as well as pressure.
Answer:
Steam-methane reforming
Electrolysis of water
Explanation:
Steam methane reforming involves reaction of methane with water in the presence of a catalyst such as nickel to form Carbon oxides and Hydrogen.
CH4 + H2O ⇌ CO + 3 H
Electrolysis of water involves splitting of water through application of electric current to give Hydrogen and Oxygen gas.
2 H2O(l) → 2 H2(g) + O2(g)
