An open system is a system that has external interactions.
a closed system is a physical system that does not allow certain types of transfers in our out of the system.
an isolated system obeys the conservation law that its total energy- mass stays constant.
stars are made when atoms of light elements are compress under enough force for their nuclei to undergo fusion.
Alaskan Natives often eat whale blubber while other groups of people typically do not. (d)This is an example of learned preferences.
What are Learning Preferences?
- Learning styles can be defined as the way in which an individual generally responds to specific learning situations and prefers to process different forms of information.
- Often, learning styles are regarded as the preferred methods for undertaking learning, for example, reader/writer, audio/visual etc., but this is a narrow definition.
- Learning preferences as a term is generally considered to take in a broader set of factors than just methods as they also take into account aspects that might impact on learning, such as: the environment and where and when students prefer to do their learning.
- For example, a student may prefer to work alone at home, and do her assignments late in the evening when the family has gone to bed. Another student may thrive in group situations and only wish to study during the day on-campus. In a nutshell, learning styles and preferences help to describe how people learn best in their context, and are useful in raising awareness about this.

To solve this problem, we can assume that the motion is
linear so that we can use the equations:
<span>Xf = Xi + v0 t + 0.5 a t^2 --->
1</span>
<span>vf = v0 + a t --->
2</span>
where Xi = initial distance = 0, v0 = initial velocity, Xf
= final distance = 26.5 m, a = acceleration = - 1.80 m/s^2, t = time = 3.81 s,
vf = final velocity
Substituting the given values into equation 1 to find for
v0:
26.5 = v0 (3.81) + 0.5 (-1.80 m/s^2) (3.81)^2
3.81 v0 = 39.56449
v0 = 10.38 m/s
Using equation 2 to find for vf:
vf = 10.38 + (-1.80) (3.81)
<span>vf = 3.53 m/s</span>
