1) You put a mass on the end of a light string so that it forms a simple pendulum that swings back and forth with a period T. If you double the mass on the end of the string, the period of the pendulum will...double.be cut in half.increase but not double.decrease but not by half.remain the same.2) When our author describes a damped harmonic oscillator, the constant b tells youthe maximum amplitude of the oscillator.how fast the amplitude of the oscillator decreases.the ratio of the spring constant to the mass of the spring.the ratio of the spring constant to the mass of the oscillating object.3) In Example 14-3, what would have been the maximum velocity of the block if it had a maximum displacement of 6.7 cm but the period remained as given in the problem?9.90 cm/sec59.70 cm/sec66.33 cm/sec72.96 cm/sec79.60 cm/sec4) A mass is oscillating up and down on the end of a spring. You would like to increase the number of times the mass goes up and down during one second of time. To do this, you could...increase the spring constant of the spring.decrease the spring constant of the spring.increase the mass of the object.decrease the mass of the object.(a) and (c)(a) and (d)(b) and (c)(b) and (d)5) A mass is swinging back and forth through small angles on the end of a very light string, forming a simple pendulum. You would like to increase the number of times the mass goes back and forth during one second of time. To do this, you could...increase the length of the string.decrease the length of the string.increase the mass of the object.decrease the mass of the object.(a) and (c)(a) and (d)(b) and (c)(b) and (d)6) In lab, you hang a brass mass to the end of a spring. After you give it a push, it moves up and down several times but its amplitude decreases every time and comes to rest after about 23 second. we would say this system is asimple harmonic oscillator.critical harmonic oscillator.damped harmonic oscillator.force harmonic oscillator.7) A mass is oscillating up and down on the end of a spring. The maximum distance the mass moves from the equilibrium position of the spring is its...frequency.period.amplitude.velocity.8) You put a mass on the end of a perfect spring so that it forms a simple harmonic oscillator that oscillates up and down with a period T. If you double the mass on the end of the spring, the period of the oscillator will...double.be cut in half.increase but not double.decrease but not by half.remain the same.9) A harmonic oscillator can be driven with a force that also oscillates. When the driving force oscillates with a frequency that is equal to the natural frequency of the original harmonic oscillator, then this system is..overdriving.underdriving.at resonance.linearly oscillating.10) In Example 14-14, what would the Q factor of the piano string have been if it lost half of its energy in 6.7 seconds?15.91 X 10317.50 X 10319.09 X 10320.68 X 10322.27 X 103
