A 2.44 gram penny is on a turn table. It starts from rest at a radius of 0.136 meters and the turn table speeds up until the pen
ny flies off with a tangential speed of 0.574 m/s.a. What coefficient of static friction exists between the penny and turntable if the penny doesn't fly off until it reaches this speed? b. Suppose a 5.7-gram quarter has the same coefficient of static friction between it and the turntable as does the penny? In what way will the speed at which it les off differ from that of the penny?
Person A hears the highest frequency from the horn than Person B because Person A is present in front of a Car 1 while the Person B present behind the Car 1. The car horn is present at the front so the Person A will hear the highest frequency from the horn as compared to Person B which hears lower frequency from the horn. If the horn is present at the back side so Person B will hear highest frequency from the horn.
