ray creates an energy transfer diagram for a hair dryer. however, the diagram contains an error that could be corrected in several different ways. which of these changes would make the diagram error - free? check all that apply. kinetic energy 125 j reducing the amount of thermal energy to 475 j increasing the amount of electrical energy to 825 j increasing the amount of sound energy to 225 j reducing the amount of kinetic energy to 50 j reducing the amount of electrical energy to 675 j sound energy 150 j electrical energy 750 j thermal energy 550 j

Answer

Explanation:

Step1: Recall energy - conservation principle

In an energy - transfer process, the total output energy should equal the input energy. Here, the input electrical energy is 750 J and the sum of output energies (kinetic + sound+ thermal) is (125 + 150+550=825) J. The error is that the sum of output energies is greater than the input energy.

Step2: Analyze each option

Option 1: reducing the amount of thermal energy to 475 J

The new sum of output energies would be (125 + 150+475 = 750) J, which equals the input electrical energy. This corrects the error.

Option 2: increasing the amount of electrical energy to 825 J

The sum of output energies ((125 + 150+550 = 825) J) would then equal the input electrical energy. This corrects the error.

Option 3: increasing the amount of sound energy to 225 J

The new sum of output energies would be (125+225 + 550=900) J, which is greater than the input electrical energy of 750 J. This does not correct the error.

Option 4: reducing the amount of kinetic energy to 50 J

The new sum of output energies would be (50+150 + 550=750) J, which equals the input electrical energy. This corrects the error.

Option 5: reducing the amount of electrical energy to 675 J

The sum of output energies ((125 + 150+550 = 825) J) is greater than the new input electrical energy of 675 J. This does not correct the error.

Answer:

reducing the amount of thermal energy to 475 J, increasing the amount of electrical energy to 825 J, reducing the amount of kinetic energy to 50 J
