Operant chamber is
laboratory apparatus consisted of the response lever, electrified grid and food dispenser.
Operant chamber (also known as Skinner’s box) is a
typical laboratory chamber (apparatus) in which the behavior and learning
process of rats was examined. This chamber is mostly empty, it has a food
dispenser, response lever which gives food when it’s pressed and sometimes
electrical greed. With this chamber, Skinner has learned in his research that
rats firstly press the lever by mistake, but that begins to happen more and
more. After some time, rats learn that when they press the lever they get food
as a reward. At the other experiment, rat have learned the same way that when
they press the lever, the electrified grid is turned off.
First, convert watts to kilowatts.
500w/1000= .5 kW per hour
.5*4 hours= 2kwh*365 days= 730 kWh
The answer is 730 kwh per year
Answer:
Explanation:
Assume that after each shaking, a silver dollar has an equal chance of "head" or "tail" up.
There will be likely 100/2 = 50 dollar coins with "heads" up. Removing them leaves 50 coins.
Again after the second shakes, 50/2 = 25 coins will likely be "heads" up. Removing them leaves 25 coins.
After the third shakes, approximately 25/2 = 12.5 coins will be "heads" up. Of course there is no 0.5 coin. Rounding up you likely get to keep 13 dollar coins.
