Two lab partners, Mary and Paul, are both farsighted. Mary has a near point of 68.6 cm from her eyes and Paul has a near point o
f 128 cm from his eyes. Both students wear glasses that correct their vision to a normal near point of 25.0 cm from their eyes, and both wear glasses 1.80 cm from their eyes. In the process of wrapping up their lab work and leaving for their next class, they exchange glasses (Mary leaves with Paul's glasses and Paul leaves with Mary's glasses). When they get to their next class, find the following. (a) Determine the distance to the closest object that Mary can see clearly (relative to her eyes) while wearing Paul's glasses.
(b) Determine the distance to the closest object that Paul can see clearly (relative to his eyes) while wearing Mary's glasses.
Atoms in absolute temperature get approximatelly motionless since 0 Kelvin is -273 degrees Celcius. The kinetic energy of atoms/particles in matter has the possible lowest value ( almost zero), so that there is nothing colder than 0 Kelvin.
