Which of the following effects is produced by the high surface tension of water? which of the following effects is produced by the high surface tension of water? a water strider can walk across the surface of a small pond. water flows upward from the roots to the leaves in plants. evaporation of sweat from the skin to keep people from overheating. lakes don't freeze solid in winter despite low temperatures. organisms resist temperature changes, although they give off heat due to chemical reactions.

A water strider can walk along the surface of earth due to the surface tension of water.

Explanation:

Fluids have a tendency to shrink to minimum possible surface area and this is called surface tension. It usually occurs due to the greater force of cohesion between molecules of same substance when compared to adhesive force between molecules of different substances. Objects with greater densities can float along water surface due to the role played by surface tension.

When insects walk along the water surface they  are pulled down due to gravity. But  the  force of attraction  between the legs of the insect and water molecules is minimal. Thus the surface tension would always tend to maintain the flatness of water overcoming the push by the legs of the strider.  

When the insect’s weight pulls it down , the surface tension pushes it upwards  overcoming this force of gravity. This is how water striders move along the surface of water.  

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.
