plz any ideas for 3
If you have been drawing free body diagrams, you should note that the reading on the scale is the tension in the cord.
hmmm i am trying it should be equal to zero the other force so they cancel each other isnt right?
In part a, the tension in the cord 'cancels out' the weight of the salami, and therfore, the salami doesn't move (F_net = 0 per Newton 1 for bodies at rest). But that does not imply the spring scale reads 0 for that case, does it? Is the scale reading in part c different from the scale reading in part b? Why or why not?
its is the same but i guess they cancel each other cuz of the same force is this correct?
The tension on each side of the spring scale is the same. But what does the spring scale read in part c?
Yes. In Newtons.
there is another problem here is the link if u could help me with that i dont even know how to start https://www.physicsforums.com/showthread.php?p=2677818#post2677818
Separate names with a comma.
