I am a Gas. I am found throughout the entire Universe. You may know me as one of the elements that makes up water. I am the most important of the 3 main building blocks of the Solar System & the Universe. I fuel stars like your Sun.

Match each scenario to the form of energy it represents

An owl dives toward the ground with a constant velocity of 4.40 m/s at 53.0° below the horizontal. the sun is directly overhead and casts a shadow of the owl directly below it. what is the speed (in m/s) of its shadow on level ground?

1. do the particles in the medium material move in the same direction of the wave or at opposite direction to the wave? explain your answer. 2. by inputting more energy into the wave, i.e a large shake of the spring, which wave property also increases? 3. are there forces of friction acting while a wave is passing through a medium?
