A guitar string is vibrating in its fundamental mode, with nodes at each end. The length of the segment of the string that is free to vibrate is 0.386 m. The maximum transverse acceleration of a point at the middle of the segment is 8.40 * 103 m>s 2 and the maximum transverse velocity is 3.80 m>s. (a) What is the amplitude of this standing wave? (b) What is the wave speed for the transverse traveling waves on this string?
1.1 Our View of the Modern Universe Monday, August 22, 2016 12:57 PM What is our place in the universe • A grand tour of the heavens ○ To survey the universe and the methods astronomersuse to study it ○ To see the measuring units used by real astronomers ○ To assess the scientific method and show how pseudoscience fails scientific tests ○ To boldly go where no class go before • The Universe ○ Some astronomersbelieve that the universe is about 14 billion years old (Maya) ○ The universe is so vast that we are actually receiving light and radio signals from the past ○ Light from the sun takes about 8 minutes ○ Light from the moontakes about 1 second ○ Light travels at a finite speed • A sense
