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?

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
