A nonrelativistic proton is confined to a length of 2.0 pm on the x-axis.What is the kinetic energy of the proton if its speed is equal to the minimum uncertainty possible in its speed? ,h = 1.055 × 10-34 J • s,mproton = 1.67 × 10-27 kg)
ABA Design
An experimental design in which participants first experience the baseline condition (A), then the intervention or treatment (B), and finally return to the baseline (A) to assess change.
Reversibility
The ability of a process or condition to be reversed or returned to its original state.
Quasi-experimental Designs
Research designs that attempt to establish a cause-and-effect relationship but lack random assignment to groups.
Random Assignment
Random assignment is a method used in experiments to assign participants or subjects to different groups in a way that is completely by chance, ensuring the groups are statistically similar in all respects at the start of the experiment.
