A wave on a string is described by y(x, t) = 15.0 sine 1Tx/8 - 4171), where x and yare in centimeters and t is in seconds. (a) What is the transverse speed for a point on the string at x = 6.00 cm when t = 0.250 s? (b) What is the maximum transverse speed of any point on the string? (c) What is the magnitude of the transverse acceleration for a point on the string at x = 6.00 cm when t = 0.250 s? (d) What is the magnitude of the maximum transverse acceleration for any point on the string?

1.) Earthquakes (3-13-17) Earthquake Strength • => intensity and magnitude scales. • 1. Intensity Scales => based on the damage done. • ⇒ Modified Mercalli Intensity Scale I to XII. This scale is used most commonly. As you go up the scale, you look at what kind of buildings are suffering damage. It is useful because people actually...
