Pl i need 35 points! 1. how are the different types of waves are formed? how do waves travel? 2. how do scientists use waves to track and analyze earthquakes? 3. discuss a recent event in the news involving earthquakes and/or tsunamis that illustrates the points you made in your answers to number 1 & 2 above. pls guys i really need with 35

Hello to answer your questions properly

Waves derive their energy and motion from the wind.All waves have the
same characteristics. The top is known as a crest,and crests are separated by troughs.Waves height is measured from trough to crest and wavelength from crest to crest.
Waves consist of energy passing through water.The wave energy moves,not the water itself.
As waves approach the shore,the water becomes shallower and the waves get higher.Finally,the wave front collapes,or breaks.The turbulent water created by breakers is called surf.

2.
They use waves to track earthquakes because the waves are jolted by the shifting of the plates causing the earthquake. Scientists use buoys in the ocean that track how big that wave is and know the magnitude of it.

3. tokyo tsunami 2011 was a recent one beacause a 9.0 earth quake caused a devastating tsunami which was tracked by buoys and was able to warn people ahead of time.

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.

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?

Consider a double atwood machine constructed as follows: a mass 4m is suspended from a string that passes over a massless pulley on frictionless bearings. the other end of this string supports a second similar pulley, over which passes a second string supporting a mass of 3m at one end and m at the other. using two suitable generalized coordinates, set up the lagrangian and use the lagrange equations to find the acceleration of the mass 4m when the system is released. explain why the top pulley rotates even though it carries equal weights on each side.
