Give an example in which kinetic energy can be converted to thermal energy.
 
  What will be an ideal response?

Question 2

The reason that most extrasolar planets discovered by the Doppler technique are found close to their parent stars is
 
  A) the closer to a star, the hotter and therefore brighter the planet is.
  B) more of the starlight is blocked by the planet when it transits the star.
  C) planets that are close to a star are heated up and therefore larger.
  D) they transit more frequently, and have thus been more likely to be detected in the short time we have been searching for them.

Answer to Question 1

The brakes on a car: applying the brakes on a car slows it down through friction of the brake pads with the brake drums. The car slows down, losing kinetic energy, and the pads warm up, gaining thermal energy (try touching your wheels-but be careful because they can become very hot-after using your brakes for a long time, e.g.,going down a steep mountain road).
