Let's say an average cow emits 100kg of methane per annum.

If coal consists of 80% carbon and 20% moisture and ash, how much
coal would I have to burn per annum to have the same global warming
potential as one cow.

Assume that the carbon in the coal burns completely.

Global warming potential is the potential of a greenhouse gas to trap heat or absorb heat

For reference CO_{2} GWP(global warming potential )=
1

and GWP of other gases is measured with

CO2 as reference

For methane GWP = 86(GWP) _{CO2} commonly
(approximately)

Cow emits 100 Kg methane /annum

Coal produces CO2 undergoing combustion

To have have same GWP as 100 Kg Methane

Amount of CO2 needed = 86(100) = 8600 Kg

CO_{2} needed = 8600 Kg/year

M. W of CO2 = 44 Kg/kmol

Moles of CO2 needed = 8600/44 = 195.454 Kmol

Coal reaction

According to stiochiometry amount of C needed to produce 195.454 kmol CO2 = 195.454(1) = 195.454 Kmol

M. W of C = 12 Kg/kmol

Kg of C needed = 12(195.454) = 2345.448 Kg

Coal contains 80% C

All C is burned

Coal needed = 2345.448/(0.8) = 2931.81 Kg

Coal burned = 2931.81 Kg/annum

Coal burned = 2.931 tons/annum

So 2931.81 Kg of Coal is burned to have same gllbal warming effect as 100 Kg methane

If a 80 W lightbulb emits 3.5 % of the input energy as visible
light (average wavelength 550 nm) uniformly in all directions,

A firm that produces electricity using coal that emits
pollution. For every part per million, P, the firm is fined
$10,000. However, it can invest in scrubbers, S, that cost $25,000
each and reduce pollution according to the formula P=10/S
Explain how the firm should approach this problem.
The cost of the fine is given by ($10,000)(P) or
($10,000)(10/S). So, each additional scrubber reduces the cost of
the fine by $100,000/S2. Find the optimal number of
scrubbers to invest in,...

In 1940 the average size of a U.S. farm was 174 acres†. Let's

Let's say your health insurance plan has the following
features:
• Deductible: $500 • Coinsurance: 80/20 (you pay the
20%; insurance company pays 80%) • Out-of-Pocket Maximum:
$5,000
Now, let's say that you go to the hospital and incur
$7,500 worth of medical expenses. How much do you have to pay out
of pocket?
What would be your out-of-pocket cost for $20,000 of
annual medical expenses?
What would be your out-of-pocket cost for $40,000 of
annual medical expenses?
