According to the law of conservation of energy, energy is not created or destroyed. It changes form or is transformed. What ener
gy transformation(s) is/are depicted here? A) electrical energy ⇒ light energy
B) potential energy ⇒ kinetic energy ⇒ light energy
C) chemical energy ⇒ electrical energy ⇒ light energy
D) chemical energy ⇒ electrical energy ⇒ heat and light energy
2)
Electrical energy is used to turn the blades of a fan. The amount of energy transformed is seen here: 750 J electrical energy is transformed into 400 J kinetic or mechanical energy. What happened to the remaining 350 J of energy?
A) It was lost due to friction.
Eliminate
B) It was transformed into 350 J of heat energy.
C) It was destroyed by the rotating blades of the fan.
D) It was never used and therefore was not transformed
Attitudes are typically more apparent in spoken language than in written text because writing allows us to easily hide our true feelings. Therefore, the correct answer is D.
This bacterium would fall into the nitrogen-fixing category. Nitrogen-fixing bacteria thrive in the soil and associate with legumes like clover, converting atmospheric nitrogen into an inorganic form that plants can utilize for growth.
