An Illustration of a transverse wave and four crests and four troughs are labeled 1 s total. Which shows the perceived sound wave heard by a stationary observer when the source moves toward the observer? An illustration of a transverse wave and three crests and three troughs are labeled 1 s total. An Illustration of a transverse wave that is taller than the previous. Three crests and three troughs are labeled 1 s total. An Illustration of a transverse wave and four crests and four troughs are labeled 1 s total. An Illustration of a transverse wave and seven crests and seven troughs are labeled 1 s total. Mark this and return

Aperson gives a shopping cart an initial push along a horizontal floor to get it moving, and then lets go. the cart travels forward along the floor, gradually slowing as it moves. consider the horizontal force(s) on the cart while it is moving forward and slowing. which of the following statements is correct? (a) both a forward and a backward force are acting on the cart, but the forward force is larger. (b) only a forward force is acting which diminishes with time. (c) both a forward and a backward force are acting on the cart, but the backward force is larger. (d) only a backward force is acting, no forward force.
