Variable reinforcement schedules generally demonstrate greater resistance to extinction than fixed reinforcement schedules. T F

The answer to the given statement is true.

This is because variable reinforcement schedules are less predictable than fixed reinforcement schedules. There are two possible types of variable reinforcement schedules: variable-ratio or variable-interval.

Variable-ratio reinforcement schedule means that the reinforcement would only be given when the individual exhibits the desired behavior according to a number of responses – these numbers are unpredictable for the subject. Variable-interval uses the same approach, however, the unpredictability lies on the period of time from when the desired behavior appears to when the reinforcement would be given.

This unpredictability causes extinction to be harder for the reinforced behavior since the subject might think that the reward for their behavior might still be given.

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27
