Determine the missing value.
a) Output value/Efficiency: 100 J
Efficiency: 100%
Input E = ???
b) Input: 100 J Efficiency: 30%
Output E = ??
Output= 30 J
c) Output E: 120 000 J
Efficiency: 2%
Input E= ??
How would I solve for the put value?
Thank you!
a. Eo/Ei = 1.0
100/Ei = 1
Solve for Ei.
b. Eo/Ei = 0.30
Eo/100 = 0.30
Solve for Eo.
c. Same procedure as a and b.
Thanks :D
To solve for the unknown value in each scenario, you need to use the formula for efficiency:
Efficiency = (Output Energy / Input Energy) * 100%
a) To find the input energy (Input E), you already have the efficiency (100%) and the output energy (100 J). Rearrange the formula to solve for Input E:
100% = (100 J / Input E) * 100%
1 = (100 J / Input E)
Input E = 100 J
b) To find the output energy (Output E), you have the input energy (100 J) and the efficiency (30%). Rearrange the formula to solve for Output E:
30% = (Output E / 100 J) * 100%
0.30 = (Output E / 100 J)
Output E = 0.30 * 100 J
Output E = 30 J
c) To find the input energy (Input E), you have the output energy (120,000 J) and the efficiency (2%). Rearrange the formula to solve for Input E:
2% = (120,000 J / Input E) * 100%
0.02 = (120,000 J / Input E)
Input E = 120,000 J / 0.02
Input E = 6,000,000 J
So, the missing values in each scenario are:
a) Input E = 100 J
b) Output E = 30 J
c) Input E = 6,000,000 J
