Three resistors A, B and C are connected in parallel and take a total of 7.9 ampere. Resistor A takes 2.5 ampere and has a resistance of 48 ohms. The current through B is twice as much as that of C. How can I calculate the currents of resistors B and C?
Subtract 2.5 from 7.9, and divide the result by 3. The result is the current of C. Multiply this by 2 to find the current of B.

Why am I seeing a message that says my local group isn't there if I am being stopped at the point of entering the command line into the second stage of this process?
Check which language you are using. The local group is probably a bit different.

How can I find the resultant if angles are not given and only magnitudes are given?
If these are vectors, and you have no other information about their direction, you can't! Since you don't know the angles (or the relative alignment) between them, it's possible that...

After I read the dry bulb and wet bulb temperature from the given hydrometer, how do I find out the relative humidity of air from the given relative humidity and table?
Try to find the difference between the wet-bulb and dry-bulb temperatures. After that, take the dry-bulb temperature and the difference you calculated, and where the columns meet on the chart...

How do I construct a line parallel to a given line if the point is from a second given line?
You can use any of the methods described above. It doesn't matter if the point is on another line; technically, every point is on an infinite number of lines, even...

I have a problem that is asking if the 2 given lines are parallel; the 2 lines are x=2, x=7. How do I do this?
The two lines are each vertical. That is, they're both perpendicular to the x-axis and parallel to the y-axis. Any two lines that are each parallel to a third line...

How do I know if lines are parallel when I am given two equations?
You would have to find the slope of each line. If the two slopes are equal, the lines are parallel. The slopes are equal if the relationship between x and...
