Take Quiz D Question 58 1 pts Which statement is correct? O Waves carry energy by transporting parts of the medium through which it travels from one place to another. Only transverse waves can transport energy. You can feel the energy transported by a wave if you hold one end of a rope while someone else vigorously shakes the other end up and down. It is possible to increase the energy carried by a wave by increasing only its wavelength.

True O False D Question 50 1 pts On a warm day, you blow up a balloon. If you place it in the refrigerator, which of these will explain what happens? The balloon will expand because the air molecules get cooler and exert more pressure on the sides of the balloon. The balloon will get smaller because the air molecules get cooler and exert more pressure on the sides of the balloon. The balloon will expand because the air molecules get cooler and exert less pressure on the sides of the balloon.
