Question

d) A short ton of coal holds about 2.24 x 107 J of energy and costs about $56.45 per short ton. How many Joules of energy in the form of coal can you get for a dollar?

Answer 1

396811.337 J

Step-by-step explanation:

The cost of one short ton of coal = $56.45

The energy related to the short ton of coal =
`2.24* 10^(7)\ J`

Thus, As according to the question,

$56.45 of coal have
`2.24* 10^(7)\ J` of energy.

$1 of coal have
`(2.24* 10^(7))/(56.45)\ J` of energy.

The amount of energy = 396811.337 J
