If an unsaturated air parcel with a temperature of 20 degrees c rises, forms a non-precipitating cloud, then returns to its original altitude, a. the parcel's final temperature will be less than 20 degrees c b. the parcel's final temperature will be greater than 20 degrees c c. the parcel's final temperature will be exactly 20 degrees c

The answer is: b. The final temperature of the package will be greater than 20 degrees C.

Explanation:

When an airbag with a temperature of 20 degrees Celsius is forced to pass through a mountain range of 2,500 m. of altitude. The dew point is reached at 900 m. and clouds form. The air is cooled approximately 1 degree Celsius every 100 meters to reach the dew point.

When the air begins to descend, its temperature rises at a rate of approximately 0.5 degree Celsius every 100 meters.

Therefore, the temperature will rise to 28 degrees Celsius after the descent.

The answer is: b. The final temperature of the package will be greater than 20 degrees C.

answer; /// the above statement is (true);

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.
