Refer to the following information for the next six questions.
Little Nellie Newton wishes to be a gymnast and hangs from a variety of positions as shown. Since she is not accelerating, the net force on her is zero. This means the upward pull of the rope(s) equals the downward pull of gravity. She weighs 300 N.
Enter the scale reading, in newtons, for each case.

Refer to the following information for the next four questions.
When Burt the painter stands in the exact middle of his staging, the left scale reads 600 N.
When he is standing in the middle, the reading on the right scale would be ___ .
This tells us that the total weight of Burt and staging must be ___ .
Burt now stands farther from the left. The reading on the right scale would be ___.
In a silly mood, Burl dangles from the right end. The reading on the right scale would be ___.
