Troposphere is the highest atmospheric layer.

The percent efficiency of a machine can never be 100% (or greater), because in the real world some energy is always converted into a. heat b. work c. input force d. output force

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

The energy of a photon was found to be 3.38 × 10–19 j. planck’s constant is 6.63 × 10–34 j • s. which color of light corresponds to this photon?
