Amount of work done is zero and so power = 0 watts.
<u>Explanation:</u>
Power is the rate at which work is done, or W divided by delta t. Since the barbell is not moving, the weightlifter is not doing work on the barbell.Therefore, if the work done is zero, then the power is also zero.It may seem unusual that the data given in question is versatile i.e. A weightlifter exerts an upward force on a 1000-N barbell and holds it at a height of 1 meter for 2 seconds. But, still the answer is zero watts , this was a tricky question although conceptual basis of question was good! Power is dependent on amount of work done which is further related to displacement and here the net displacement is zero ! Hence, amount of work done is zero and so power = 0 watts.
-- In combination with 610 Hz, the beat frequency is 4 Hz.
So the unknown frequency is either (610+4) = 614 Hz
or else (610-4) = 606 Hz.
In combination with 605 Hz, the beat frequency will be
either (614-605) = 9 Hz or else (606-605) = 1 Hz.
-- In actuality, when combined with the 605 Hz, the beat
frequency is too high to count accurately. That must be
the 9 Hz rather than the 1 Hz.
So the unknown is (605+9) = 614 Hz.
Answer:Habituation is a simple learned behavior in which an animal gradually stops responding to a repeated stimulus.
Imprinting is a specialized form of learning that occurs during a brief period in young animals—e.g., ducks imprinting on their mother.
In classical conditioning, a new stimulus is associated with a pre-existing response through repeated pairing of new and previously known stimuli.
In operant conditioning, an animal learns to perform a behavior more or less frequently through a reward or punishment that follows the behavior.
Some animals, especially primates, are capable of more complex forms of learning, such as problem-solving and the construction of mental maps.
Introduction
If you own a dog—or have a friend who owns a dog—you probably know that dogs can be trained to do things like sit, beg, roll over, and play dead. These are examples of learned behaviors, and dogs can be capable of significant learning. By some estimates, a very clever dog has cognitive abilities on par with a two-and-a-half-year-old human!
Explanation:
Answer:
30 kilometers is a reasonable measurement
They are too small are never in the same place. Electrons are constantly moving in random motion within the electron cloud, making them impossible to follow.
