No, this website is not for study groups. It's more of a 'question and answer' website. There is no actual communication on one certain subject. Although I do know a few websites that have worked really well for me,where you can create and participate in study groups;
-studyblue
- studyhall
- getstudyroom
all of these are safe websites that are used by wide variety of students, therefore i'm sure you can find plenty of people interested in learning the same things as you!
Answer:
It simply means that other teams can independently complete the feature.
Explanation:
PI or program increment is a planning interval during which an agile release train (ART) plans and produces working and tested software and systems. It takes a duration of 8 to 12 weeks
Agile teams can access and independently complete various ARTs found in their swim lanes with no strings.
Answer:
The Lead Designer
Explanation:
The Lead designers main role is to oversee how a game looks and is played. They manage a, normally small, design team. They work with them to come up with many aspects of the game itself like; characters, props, and plots to the game. they also, makes sure that the team itself stays on track, is within budget, and meets the designated deadlines.
convection requires a medium is not the main difference, it is simply the most obvious aspect of what is a fundamentally different mechanism for transfering energy. Convection is the transfer of energy by movement of a medium, whereas radiation is the transfer of energy by, well, thermal radiation. Conduction also requires a medium, but, again, it is a fundamentally different mechanism than either convection or radiation; in this case it is the transfer of energy through a medium.
Unfortunately, analogies are hard but if you can visualize the particles involved, it would help. Picture the red hot iron you mentioned. On a molecular level, the material is emitting lots and lots of photons (hence why it is glowing red). The creation of these photons takes energy; energy from the heat of the iron. These photons leave the iron, pass through the environment, and eventually collide with some other object where they are absorbed and deposit their energy. This is radiative heat transfer. If that energy is deposited on your retina or a CCD (like in a digital camera), an image forms over time. This is how infrared goggles work and they would work equally well in high vacuum as here on earth.
In conduction, the next simplest example, there is no generation of photons (physics nerds forgive me for the sake of simplicity). The individual atoms in the object are vibrating with heat energy. As each atom gains energy from it's more energetic neighbors, so it gives up energy to its less energetic ones. Over time, the heat "travels" through the object.
In convection, the molecules of gas near the object gain energy, like in the conduction case, but those same molecules that gained energy then travel through the environment to some other location where they then give off their heat energy.
In summary:
radiation = generated and absorbed photonsconduction = molecules exciting their neighbors succesivelyconvection = molecules heated like in conduction, but then move to another location
