Avertically hung spring has a spring constant of 150. newtons per meter. a
2.00-kilogram mass is suspended from the spring and allowed to come to rest.

72–73 calculate the total elastic potential energy stored in the spring due to the suspended
2.00-kilogram mass. [show all work, including the equation and substitution with units.]

Describe different biomes. what are some adaptations that organisms (plants or animals) must have to live in each biome?

Aperson stands on a platform, initially at rest, that can rotate freely without friction. the moment of inertia of the person plus the platform is ip. the person holds a spinning bicycle wheel with its axis horizontal. the wheel has moment of inertia iw and angular velocity ωw. take the ωw direction counterclockwise when viewed from above. part a what will be the angular velocity ωp of the platform if the person moves the axis of the wheel so that it points vertically upward?

Avolcano erupts next to a grassland area in a valley. a. describe three ways in which material released by the volcano could impact the grassland area. b. describe three ways in which the grassland ecosystem could recover after a volcanic eruption.
