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.

Explanation:
Given parameters:
Distance = 15miles north = 24140.2m
Initial velocity = 0m/s
Final velocity = 4m/s
Unknown:
Speed, velocity and acceleration = ?
Solution:
The speed is the distance divide by time. It is a scalar quantity and has no directional attribute.
Speed =
The speed of the student is 4m/s
Velocity is the displacement divided by time. It is a vector quantity which specifies the direction and magnitude;
Velocity =
The velocity of the student is 4m/s due north
Acceleration is the change in velocity with time;
To find the acceleration, we use
v² = u² + 2as
v is the final velocity
u is the initial velocity
a is the acceleration
s is the distance
4² = 0² + 2x a x 24140.2
a = = 0.00033m/s²
Answer:
Movement of electrons
Explanation:
when electrons move from a point to another, they carry along charges in the course of moving. Charges could be through metallic objects and as well could be through some conducting solution.
That leads us to Ohm's Law : it states that current flowing through a metallic conductor is directly proportional to the potential difference across its ends, provided that temperature remains constant. So for charges to flow through a conductor, there are factors to be considered.
A) if energy is being absorbed, then more hydrogen bonds are being broken (melting). If energy is being released, more hydrogen bonds become fixed (freezing).
<span>b) during melting, hydrogen bonds get broken and movement can occur. During freezing, hydrogen bonds become fixed and water molecules cannot move as much.
