You have your remote pilot certificate and want to fly with another pilot whose certificate has expired. you plan to use a buddy box system. how does this work? group of answer choices each pilot has his or her own control system, and you have the ability to override controls. each pilot has his or her own control station. the pic with the expired certificate is controlling the ua, and you are assisting with your own control station. there is one control system, and you're positioned close enough to the pilot where you can take control within 30 seconds

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?

Could someone . i have tried to solve myself but my calculation is off

What are similarities and differences between refraction, reflection, diffraction and absorption?
