The amplitude of an oscillator decreases to 36.8% of its initial value in 10.0 s. What is the value of the time constant?

What are the (a) amplitude, (b) frequency, and (c) phase constant of the oscillation shown in FIGURE EX15.6?

FIGURE EX15.7 is the position-versus-time graph of a particle in simple harmonic motion.a. What is the phase constant?

An object in SHM oscillates with a period of 4.0 s and an amplitude of 10 cm. How long does the object take to move from x = 0.0 cm to x = 6.0 cm?

FIGURE EX15.7 is the position-versus-time graph of a particle in simple harmonic motion.c. What is vₘₐₓ?

An object in simple harmonic motion has an amplitude of 8.0 cm, n angular frequency of 0.25 rad/s, and a phase constant of π rad. Draw a velocity graph showing two cycles of the motion.

When a guitar string plays the note 'A,' the string vibrates at 440 Hz. What is the period of the vibration?

The intensity of electromagnetic waves from the sun is 1.4 kW/m² just above the earth's atmosphere. Eighty percent of this reaches the surface at noon on a clear summer day. Suppose you think of your back as a 30 cm x 50 cm rectangle. How many joules of solar energy fall on your back as you work on your tan for 1.0 h?

LASIK eye surgery uses pulses of laser light to shave off tissue from the cornea, reshaping it. A typical LASIK laser emits a 1.0-mm-diameter laser beam with a wavelength of 193 nm. Each laser pulse lasts 15 ns and contains 1.0 mJ of light energy.b. During the very brief time of the pulse, what is the intensity of the light wave?
