A graph titled Position versus Time shows time in seconds on the x axis, numbered 0 to 5, position in meters on the y axis, numbered 0 to 4. The graph has a horizontal line starting at (0, 3) to (5, 3). Given the information in the velocity vs. time graph, what is the displacement of the object after 1 second? m After 3 seconds? m After 5 seconds? m

What property is a characteristic of a substance that can be observed and does not change the identity of the substance

1. consider the case in which air fills air shocks on a truck trailer. the pressure in the shocks is 2 mpa. the temperature is 300 k. the diameter of the shock piston is 10 cm and the initial length of the cylindrical cavity containing the compressed air is 40 cm. a. the truck is gradually loaded over a period of a day in a static setting. the temperature is held constant for the atmosphere and thus for the gas shock. calculate the compressibility of the air in the shock for this condition when the truck is initially being loaded. b. if the shocks were loaded in a dynamic setting by driving over bumps, what would be the compressibility? state your assumption. c. what is the initial load on the shock if the shock is in an atmospheric 100 kpa? d. if the shock is compressed using the process described in part a, and the air shock compressed air cavity length decreases to 20 cm, what is the additional load applied to the shock?
