Title: Given 4 tuning forks of frequency 446, 440, 443, and 449 Hz, how many different beat frequencies ... Post by: Hoshuia on Mar 19, 2018 Given 4 tuning forks of frequency 446, 440, 443, and 449 Hz, how many different beat frequencies could be produced and what are they?
What will be an ideal response? Question 2 The mass of a mass-and-spring system is displaced 10 cm from its equilibrium position and released. A frequency of 4 Hz is observed. What frequency would be observed if the mass had been displaced only 5 cm and then released? A) 8 Hz B) 4 Hz C) 6 Hz D) 2 Hz Question 3 Consider point charges of +Q and +4Q, which are separated by 3 m. At what point, on a line between the two charges, would it be possible to place a charge of -Q such that the electrostatic force acting on it would be zero? A) 3/5 m from the +Q charge B) 1 m from the +Q charge C) 1 m from the +4 charge D) 3 m from the +4 charge E) There is no such point possible. Question 4 A heavy bus bar is 20. cm long and of rectangular cross-section, 1.0 cm 2.0 cm. What is the voltage drop along its length when it carries 4000. A? (The resistivity of copper is 1.69 10-8 -m.) What will be an ideal response? Question 5 The fact that Encephalization Quotients (EQs) of organisms have generally increased with time provides evidence for A) cross-breeding between organisms B) artificial selection C) genetic mutations D) convergent evolution toward intelligence Question 6 In which eon of Earth's history did life originate? A) Proterozoic B) Phanerozoic C) Archean D) Hadean Title: Given 4 tuning forks of frequency 446, 440, 443, and 449 Hz, how many different beat frequencies ...
