a) One day, Arif is kidnapped by aliens who come to his carpet shop to take him a completely different planet. When Arif sees the world through the window of the cabin he is in, he is shocked and realizes that he is in space. When he calms down, he begins to look for ways to return to the world. He decides to call Muhittin, one of his close friends, to ask help. Assuming Arif is within the area that his mobile phone operator can work, does his mobile phone work in space? In other words, can the Muhittin's phone ring when Arif calls him? Explain why Arif's mobile phone can or cannot work. (Hint: Mobile phones work by emitting electromagnetic waves) (17 pts). b) When Arif gets off the spaceship in space, he sees a big explosion about 3 km away from him. Can Arif hear the explosion? Explain why he can or cannot hear (Assume that Arif is at a safe and appropriate distance to hear the sound at the time of the explosion and his clothes do not shield the sounds) (17 pts). 3
