question 14

Multiple Choice

Two bars,A and B,each of length 2.0 m and cross sectional area 1.0 m²,are placed end to end as shown in the figure.
The thermal conductivities of the bars are
k_A = 439 J/(s × m × K) and k_B = 887 J/(s × m × K) ,respectively.The left end of bar A is maintained at 373 K while the right end of B is maintained at 273 K.
-Which one of the following statements is true concerning the above situation?

• A)For a given time t,the amount of heat transferred through bar A is the same as that through B.
• B)For a given time t,the amount of heat transferred through bar A is smaller than that through B.
• C)For a given time t,the amount of heat transferred through bar A is less than that through B.
• D)The time for a quantity of heat Q to pass through bar A is less than that for B.
• E)Time is not a factor in determining the quantity of heat conducted through these bars.

Definitions:

Secondary Reinforcement

A process wherein a stimulus reinforces a behavior because it is associated with a primary reinforcer (e.g., praise that becomes rewarding because it is linked to receiving a physical reward).

Negative Reinforcement

A behavior modification technique that involves the removal of an unpleasant stimulus to increase the likelihood of a desired response.

Positive Reinforcement

Any pleasant or desirable consequence that follows a response and increases the probability that the response will be repeated.

Punishment

A consequence that reduces the likelihood of a behavior being repeated in the future.
