D is the wrong answer. New information does often completely change the theory. Its hard to change something and leave the major theory intact.
The answer is A). Moving from A to C the temperature and the kinetic energy increases.
We use a fundamental kinematic equation as follows:
V = Vo + g*t.
<span>Tr = (V-Vo)/g = (0-10)/-10 = 1 s. = </span><span>time to reach max. height </span>
<span>Tf = Tr = 1 s. = Fall time or time to fall back to edge of bldg. </span>
<span>3-Tr-Tf = 3-1-1 = 1 s. Below edge of bldg. </span>
<span>d = Vo*t + 0.5g*t^2. </span>
<span>d = 10*1 + 5*1^2 = 15 m. <---- OPTION C</span>
A :-) a = v^2 by r
Given - radius = 25 m
velocity = 10 m/s
Solution -
a = v^2 by r
a = ( 10 )^2 by 25
a = 100 by 25
( cut 25 and 100 because 25 x 4 = 100 )
a = 4 m/s^2
.:. The centripetal acceleration of the car
= 4 m/s^2.
The answer to the given question above is option C. In a classical conditioning experiment, you ring a bell but no longer provide dinner to your subject, a beagle and at last, the CS no longer evokes the CR so therefore, <span> you've accomplished behavioral EXTINCTION. Hope this helps.</span>
