Numeric Response 5. If a particular fur furnace is 8.30% efficient and uses 1500 J of energy, then the useful output energy is __ J. (Record your answer in the numerical-response section below.) Your answer: square square square square

To find the useful output energy of the furnace, we need to calculate the amount of energy that is effectively used based on its efficiency.<br /><br />The formula to calculate the useful output energy is:<br /><br />\[<br />\text{Useful Output Energy} = \text{Efficiency} \times \text{Total Input Energy}<br />\]<br /><br />Given:<br />- Efficiency = 8.30% = 0.083 (as a decimal)<br />- Total Input Energy = 1500 J<br /><br />Substitute these values into the formula:<br /><br />\[<br />\text{Useful Output Energy} = 0.083 \times 1500<br />\]<br /><br />Calculate the result:<br /><br />\[<br />\text{Useful Output Energy} = 124.5 \, \text{J}<br />\]<br /><br />Therefore, the useful output energy is 124.5 J.
