The correct answer is A.
W is sound because it is transported by mechanical waves, which are vibrations of materials.
X is heat because it is transported by mechanical waves, which are vibrations of materials.
Y is mechanical because it is transported by mechanical waves, which are vibrations of materials.
Z is electrical because it is transported by electromagnetic waves, which are the interaction of charges.
The table identifies how several types of energy are transported and generated.
Energy Type Method of Transportation How Generated
W electromagnetic waves internal motion of particles
X mechanical waves vibration of materials
Y mechanical waves application of work
Z electromagnetic waves interaction of charges
Which of the following correctly identifies each energy type?
A
W is sound, X is heat, Y is mechanical, and Z is electrical.
B
W is electrical, X is mechanical, Y is heat, and Z is sound.
C
W is electrical, X is mechanical, Y is sound, and Z is heat.
D
W is heat, X is sound, Y is mechanical, and Z is electrical.
