Ben is super late to his Physics class and so he bolts up the stairs 15m and makes a right and runs down the hall 20 m to get to his class. Determine the magnitude of Ben's
displacement.
Hint: On your scratch paper, draw a diagram of your vectors. Use tip to tail method.
Draw a dotted line from where he started to where he finishes to make a triangle. Use
the Pythagorean theorem to solve and figure out the magnitude.

Amplitude is a measure of a waves a; speed b; distance c; energy d; frequency

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?

Which statement is best supported by the information in the chart? wave y is moving the fastest. wave x is moving the fastest. all of the waves are moving at the same speed. all of the waves have the same value of wavelengths per second.
