1. When using the scale to measure the mass of the cylinder in an Archimedes' Principle Lab experiment, does it experience a buoyant force due to its immersion in air? If so, approximate the magnitude of this buoyant force.

2. When using the scale to measure the submerged cylinder in an Archimedes' Principle Lab experiment, does it matter if the cylinder touches the bottom of the beaker in which it is submerged? How would such contact affect your measurement, if it all?

***THERE IS NO DIAGRAM MISSING HERE!

1. Yes, the cylinder experiences buoyant force as it is immersed in air(fluid). The buoyant force on the cylinder is equal to the weight of the air displaced by the cylinder = (density of air) * (g) * (volume of the cylinder)

2. Yes it matters when the cylinder touches the bottom of the beaker. When the cylinder touches the beaker, normal force acts on the cylinder. It acts in up direction. The reading of the scale decreases as part of the weight of the cylinder is now supported by the normal force.
