T The earth is built up and torn down in many ways. Physical and chemical weathering
are processes which are very important in making soil. Which statement accurately
describes an example of chemical weathering?
O Sinkholes are formed in Florida as water dissolves underground limestone rocks.
In order for rock to become metamorphic rock, it must be heated and extreme pressure
applied.
O In Alaska, rocks are broken due to continuous freezing and thawing of water sitting in cracks.
Beautiful and strange rocks, shaped by blowing sand, dot the Western United States
landscape

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?

Auniform crate c with mass mc is being transported to the left by a forklift with a constant speed v1. what is the magnitude of the angular momentum of the crate about point a, that is, the point of contact between the front tire of the forklift and the ground
