How do you calculate the density of a non-uniform object?
The density of a non-uniform object can be found by using its mass and volume. The volume can be measured by placing the object in volumetric glassware filled with water. The increase in volume is equal to the volume of the object. The object can then be weighed using a scale. The density of the object will be given by the ratio of mass / volume.
Which of these terms is defined as observations that are made using the scientific method and used as evidence?

How would throwing an object affect the fingerprint left on it?
Assuming the fingers are in contact to push or pull the object, the amount of pressure put on the fingers to move an object would increase with the weight of the object. This results because friction force that must be overcome to push or pull the object is proportional to the object's weight. [Elementary physics.] And the print definition varies with the pressure used to implant the fingerprint. If the fingers are not pressed hard enough against the object, some of the print will be missing from the object. If they are pressed too hard, the print will be smudged and ill-defined. And that's the answer. Fingerprints are likely to be smudged with moving heavy objects, missing in part with moving light objects, and better defined when moving medium weight objects. All this assumes we're using the fingers in all cases. In fact, we'd probably use the palms of our hands if we are moving heavy objects; so the fingers might not even touch the object.
