Answer:
dependent variable -- As it depends on the other variables, changes when they change
These were later renamed to "Specialized Technology" and "Simscape Components" to help explain this difference.
Specialized Technology (Second Generation) is a Simulink based library and has been around for longer. It can still connect to Simscape, but in the same way you can connect Simulink models to Simscape -- that is, you need converters and sometimes to break algebraic loops, etc. It also has more dedicated electrical power systems capabilities. If your model will be only power systems, and especially if it's a larger model, I'd recommend this one.
Simscape Components (Third Generation) is built using the Simscape language and therefore connects directly with other Simscape blocks. If you plan to use other Simscape domains like mechanical, hydraulic, etc. I'd recommend this one.
Answer:
To protect a formula
Explanation:
One common example to apply cell protection to spreadsheet entries is to protect a formula used in the sheet to calculate payouts or rankings for example. A manager might want to share the results of the team to all its team and provides some ranking or other form of calculations in the sheet. He then needs to protect the formula so it's not altered by the team members or anyone else reviewing the file.
Answer:
Following are the response to the given question:
Explanation:
The glamorous objective is to examine the items (as being the most valuable and "cheapest" items are chosen) while no item is selectable - in other words, the loading can be reached.
Assume that such a strategy also isn't optimum, this is that there is the set of items not including one of the selfish strategy items (say, i-th item), but instead a heavy, less valuable item j, with j > i and is optimal.
As 
, the i-th item may be substituted by the j-th item, as well as the overall load is still sustainable. Moreover, because 
and this strategy is better, our total profit has dropped. Contradiction.
