A sinusoidal wave moving along a string is shown twice in the figure, as crest \( A \) travels in the positive direction of an \( x \) axis by distance \( d=6.10 \mathrm{~cm} \) in \( 4.20 \mathrm{~ms} \). The tick marks along the axis are separated by \( 13.0 \mathrm{~cm} \); height \( H \) \( =6.80 \mathrm{~mm} \). If the wave equation is of the form \( y(x, t)=y_{m} \sin (k x \pm \omega t) \), what are (a) \( y_{m} \), (b) \( k \), (c) \( \omega \), and (d) the correct choice of sign in front of \( \omega \) ? (a) Number \( \mathrm{mm} \) (b) Number Units (c) Number Units
