When you sit still in a chair with your feet on the ground and your back pressing against the back of the chair, are the forces acting on you balanced? explain. are the forces acting on you balanced if you lift your feet off the floor but remain still? explain. lastly, if you tilt back in your chair (not recommended! ) and you fall backwards to the floor, are the forces acting on you balanced while you are falling? explain. how about after you have hit the floor? explain.

Yes, the forces are balanced, gravity pulling you down and normal force supporting you up. The same works if you are holding your feet up only difference would be that you would have no normal force supporting your feet but more normal force supporting you at your bottom.
As you are falling you now have unbalanced force, the force of gravity pulling you down is greater than the forces holding you from moving (pretty much just a little bit of drag (air resistance)
Once you come to rest on the floor and stop the forces are balanced once again as the force of gravity pulling you down is equal to the normal force of the floor supporting you.

elly's long hair:

a. if the salon only takes cash, then this isn't the problem. it doesn't matter how much she has in her checking account. she can't get a haircut until she has the cash.

b. if she has overdraft protection, then there's no problem. she can go ahead and write a check that her account can't cover, then sometime later, pay the bank some outrageous usury for loaning her a few bucks for a few days, but with beautiful hair.

c. if elly has some principles, and doesn't want to write a bad check, then now she has a problem. her desire for the new hairstyle is in conflict with her honesty and integrity.

d. if the bank will not process a check she writes, then even if she had a million $$ in her account, she couldn't use any of it. the amount she has in her account is not the problem. and if i may suggest, she might as well close her checking account, and put the money where it'll work for her. it's not doing her a bit of good in a checking account, since she can't write any checks.

justin can't pay the full balance:

a. he can't even handle the credit limit he has now. under no circumstances should he ask for a higher limit.

b. he can ask for the grace period to be extended. but that's no solution, the bank will almost certainly refuse anyway, and there are much better options. he knew the rules of his credit card when he started using it.

c. he definitely should pay the interest on the balance, plus as much of the balance as he can cover at the same time.

d. he definitely should pay the minimum otherwise they could shut down his card. he should also pay as much more as he possibly can. he should also remember the awkward situation he's in, stop buying stuff on credit that he can't afford, and avoid adding any more debt.

i'd say that justin's best best option isn't on this list of choices. what he has to do: pay as much as he can at least the minimum payment plus as much more as he can and then avoid adding more debt.

Iread this book last year so take this with a grain of salt.gene jumps from the tree to compete with finny due to the fact that gene is always trying to do better than finny. he is put under the grasp of peer pressure due to finny almost forcing him to do this. ever since he first jumped finny kept pressuring him to jump since he thought gene enjoyed jumping.rather than uses this answer you should probably just reread chapters 3-4
