The graph below shows the distance traveled by the skateboarder on each of the different road conditions. Using the graph, determine which of the roads was dry, wet, or muddy. Explain your answer using complete sentences. Road A in the graph would represent (dry, wet, muddy), and here is why:

Road B in the graph would represent (dry, wet, muddy), and here is why:

Road C in the graph would represent (dry, wet, muddy), and here is why:

Wo audio speakers are placed on a vertical rail. speaker a is placed at head-level while speaker b is place at some variable height, \delta yδy, above speaker a. both speakers receive simultaneous input from a sine-wave generator so the speakers each produce a pure sinusoidal sound wave with a wavelength of 0.531 meters. calculate the lowest height that speaker b can be placed above speaker a to produce a minimum of sound heard by person standing \delta x = 7.86δx=7.86 meters directly in front of speaker a.

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k
