Blood donations can be used to save lives for people suffering from blood loss due to traumatic injury. However, other times only certain components of the blood are needed. For example, platelets can be donated and used to help in cases where a clotting factor is missing in a patient. The fractioning of blood into its components is shown here. What experimental design was most likely used to provide evidence for the success in blood fractioning?

probably not if net force is zero

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.
