What is the frequency of a mechanical wave that has a velocity of 1.70m/s and a wavelength of 12.05m

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.

If forces acting on an object are unbalanced. true or false

Awater slide of length l has a vertical drop of h. abby's mass is m. an average friction force of magnitude f opposes her motion. she starts down the slide at initial speed vi. use work-energy ideas to develop an expression for her speed at the bottom of the slide. then evaluate your result using unit analysis and limiting case analysis. express your answer in terms of the variables h, m, l, vi, f and appropriate constants. vf v f
