Question

Suppose a cup of hot chocolate is sitting a table. A woman puts her hand close to the cup on its right side, but not touching (as in the image). Nonetheless, her hand begins feeling a bit warmer. When she grasps the cups, she feels her hand warming up even more rapidly The energy diagrams below right demonstrate the mechanisms involved in making her hand warmer. Infrared Radiation Interaction Heat Conduction Interaction Cup of hot chocolate E Cup of hoft chocolate LE Energy Hand Energy Hand Decrease in thermal energy Increase in thermal energy Decrease in thermal energy Increase in thermal energy Hand near cup Hand holding cup (Note that these diagrams are incomplete, because both the cup and hand also transfer energy to the surroundings through heat interactions. These interactions are not shown because they are not needed for answering this question.)

Answer 1

Option a is correct.

Because electromagnetic radiation is emitted when charged particles are accelerated.
