Question

which statement best describes the work and energy in these examples? example 1: running a car requires gas. example 2: humans require food to live. the gas and food are examples of energy. the gas and food are examples of work. the gas and humans are examples of work. the food and car are examples of energy.

Explanation:

To solve this, we analyze each option:

• Option 1: Gas (chemical energy) and food (chemical energy from nutrients) are sources of energy. A car uses gas energy to run, humans use food energy to live.
• Option 2: Work is the transfer of energy, gas and food are energy sources, not work.
• Option 3: Gas is energy, humans perform work, so this is incorrect.
• Option 4: A car is a machine, not energy; food is energy. So this is incorrect.

Answer:

The gas and food are examples of energy.
