This is an example of classical conditioning, and the library is a conditioned stimulus.
The idea of classical conditioning was first put forward by the man Ivan Pavlov, a Russian physiologist.
In his studies, he was able to successfully associate a once neutral stimulus to a conditioned response. The neutral stimulus hitherto does not produce the expected response until after conditioning has taken place.
In this case, the library was a neutral stimulus. When it becomes associated with a bakery, it provokes the conditioned response of hunger any time you go to the library.
The library is now a conditioned stimulus.

Answer:
a) Centripetal force = 80.4 N
b) Tension in the monkey's arm = 167.7 N
Explanation:
The centripetal force is the force keeping the monkey in circular motion and it is given by
F = (mv²/r)
m = mass of the monkey = 8.91 kg
v = velocity of the monkey = 2.61 m/s
r = 75.5 cm = 0.755 m
F = (8.91×2.61²)/0.755
F = 80.4 N
b) At the lowest point, there are 3 forces acting on the monkey, the tension in the arm, the monkey's weight and the centripetal force.
A quick force balance on the monkey at the lowest point gives
F = T - mg
80.4 = T - (8.91×9.8)
T = 80.4 + 87.32
T = 167.72 N
Answer:
, 6.1 s
Explanation:
The motion of the dropped penny is a uniformly accelerated motion, with constant acceleration
towards the ground. If the penny is dropped from a height of
the vertical position of the penny at time t is given by the equation
where the negative sign is due to the fact that the direction of the acceleration is downward.
We want to know the time t at which the penny reaches the ground, which means h(t)=0. Substituting into the equation, it becomes
And re-arranging it, we find an expression for the time t:
And substituting the numbers, we can also find the numerical value:
2 meters per second for 10 seconds is speed(2) multiplied by time(10)which is equal to 20meters
All u have to do is see how much mass the rover has, and then multiply that value by 3.71
