question 1\nwhich of the following situations represents released energy:\n(1) a dart shot out of a dart gun,\n(2) a compressed spring in a dart gun, or\n(3) active transport of a substance across a cellular membrane?
Answer
Brief Explanations:
- When a dart is shot out of a dart - gun, the elastic potential energy stored in the compressed spring is converted into the kinetic energy of the dart, releasing energy.
- A compressed spring in a dart - gun has stored elastic potential energy, but it hasn't released energy yet; it is in a state of storing energy.
- Active transport of a substance across a cellular membrane requires energy input (usually in the form of ATP hydrolysis) rather than releasing energy.
