A pulse of the shape below originates in spring A. The speed of the pulse in this spring is 4.0 m/s. Another spring, B, is connected to spring A. The speed of the
pulse in spring B is 2.0 m/s. The "short" end of the original pulse is the right side
with the steep decline.
1) Draw a diagram showing the reflected pulse. In your diagram, pay particular
attention to the wavelength of the reflected pulse, the amplitude of the pulse,
whether or not it is inverted, and in what direction the "short" end of the pulse is
facing

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.

Abag of potato chips contains 2.00 l of air when it is sealed at sea level at a pressure of 1.00 atm and a temperature of 20.0 deg c. what will be the volume of the air in the bag if you take it with you, still sealed, to the mountains where the temperature is 7.00 deg c and atmospheric pressure is 70.0 kpa? assume that the bag behaves like a balloon and that the air in the bag is in thermal equilibrium with the outside air.
