Answer
He indroduced the intelligence quotient (IQ) as a test in intelligence
Explanation
William Stern's contributions were majorly influenced by previous works of Binet and the study of children intelligence. He introduced an intelligence quotient IQ as the ratio of mental age to chronological age.
<span>COGNITIVE bias describes when your likes and dislikes affect how you think about something.
Cognitive bias encompasses a lot of biases. This bias is identified as an objective thinking limitation because your brain perceives information based on your personal experience and preference.
A lot of people tend to think negatively of things and ideas that they deem impossible or improbable or they have not personally experienced. They tend to be closed minded thus their life experiences will be limited.
Another example is when you undergo a trauma in any time of your life, the long term effect would be that you veer away from situations that are similar to the situation that led to the traumatic event. Because you already have a preconceived notion of an object or ideas, you tend to draw conclusion from this preconceptions and make generalizations that may be erroneous.</span>
B.
increases as the tension of the string increases
Explanation :
As the ambulance got closer, Marge noticed that the pitch of the siren got higher. This is due to the Doppler's effect.
The siren of the ambulance has a higher pitch when it approaches Marge. When the waves move away from him, it will have a lower pitch.
As the waves come closer to us, the waves become compressed and hence the frequency of the wave increases.
A) Using:
2as = v² - u², where v will be 0 at max height
s = -(160)² / 2 x -32.174
s = 397.8 ft
b) Using:
s = ut + 1/2 at²
256 = 160t - 16.1t²
solving for t,
t = 2.0, t = 7.9
Now, v = u + at, for both times:
v(2) = 160 - 32.174(2)
v(2) = 95.7 ft/sec on the way up
v(7.9) = 160 - 32.174(7.9)
v(7.9) = -94.3 ft/sec; 94.3 ft/sec on the way down
c) -32.174 ft/s², which is the acceleration due to gravity.
d) s = 0
0 = 160t - 1/2 x 32.174t²
t = 9.94 seconds
