Answer:
Both attempt to explain human behavior
Explanation:
Psychology is generally regarded as the science of human behavior. Behaviourism is the psychological theory which holds that behaviour can be fully understood in terms of conditioning, without actually considering thoughts or feelings. The theory holds that psychological disorders can be aptly handled by simply altering the behavioural patterns of the individual. It involves the study of stimulus and responses.
Cognitive psychology attempts to decipher what is going on in people's minds. That is, it looks at the mind as a processor of information. Hence we can define cognitive psychology as the study of the internal mental processes. This according to behaviorists, cannot be studied in measurable terms as in behaviourism (stimulus response approach) even though mental processes are known to influence human behavior significantly.
Hence, both behaviourism and cognitive psychology attempt to study human behavior from different perspectives.
No because point A has to be higher for more KE to push the object and make the look
Frequency is given in units of Hertz (Hz) and is defined as the number of cycles per second. The sound wave has 30,000 cycles per second, so its frequency is 30,000Hz.
This is more conveniently expressed as 30kHz, where the k indicates a multiplier of 1,000.
Answer:
<em>The correct answer is (a) 312.5nm and (b) 125nm</em>
Explanation:
<em>The first step to take is to find The minimum thickness of the slick of the oil</em>
<em>Given that,</em>
<em>(a) tmin λ/2n </em>
<em>We substitute 750nm ( in air) for λ and 1.20 for n for the expression of minimum thickness t of the oil slick at that spot</em>
<em>thus,</em>
<em>tmin = (750nm)/2(1.2) = 312.5nm</em>
<em>The minimum thickness of the oil slick at that spot is =312.5nm</em>
<em>(B) we find the minimum thickness t </em>
<em>The minimum thickness of the oil slick at the spot will be calculated by,</em>
<em>tmin = λ/4n</em>
<em>we then 750nm ( in air) for λ and 1.50 for n in the expression for the minimum thickness of the slick of the oil.</em>
<em>tmin = (750nm)/4 (1.5) = 125nm</em>
<em>Therefore the minimum thickness t will now be = 125nm</em>
