An Oxygen Molecule,O₂,falls in a Vacuum

question 5

Multiple Choice

An oxygen molecule,O₂,falls in a vacuum.From what height must it fall so that its translational kinetic energy at the bottom of its fall equals the average translational kinetic energy of an oxygen molecule at 920 K? The mass of one O₂ molecule is 5.312 × 10^-26 kg,and the Boltzmann constant is 1.38 × 10^-23 J/K.Neglect air resistance and assume that g remains constant at 9.8 m/s² throughout the fall of the molecule.

• A)49 km
• B)12 km
• C)24 km
• D)37 km
• E)5.2 km

Skinner

B.F. Skinner was an American psychologist and behaviorist who developed the theory of operant conditioning, focusing on how behavior is influenced by its consequences.

Conditioned Emotional Responses

Emotional reactions that have been learned through classical conditioning, such as fear or joy associated with specific stimuli.

Classical Conditioning

A learning process that occurs when two stimuli are repeatedly paired; a response that is initially elicited by the second stimulus is eventually elicited by the first stimulus alone.

Observational Learning

A learning process where individuals acquire new behaviors, skills, or attitudes by watching others, particularly those they consider models.
