A mass of 0.079 kg hangs from a vertical spring in the lab room. You pull down on the mass and throw it vertically downward. The speed of the mass just after leaving your hand is 3.80 m/s.(a) While the mass moves downward a distance of 0.11 m, how much work was done on the mass by the Earth? Include the appropriate sign. Work done by Earth = J(b) At the instant in part (a) when the mass has moved downward a distance of 0.11 m, the speed of the mass has decreased to 1.52 m/s. How much work was done on the mass by the spring? Include the appropriate sign. Work done by spring = J

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d

c) up is the direction the magnetic force is acting on the charge.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.

part 1: which substance has a higher solubility?

a

smallest amount left undissolved atall temps in table shown most has dissolved high sol'by
