Boat Mini will sound waves move a sail boat in water?
for a science project we are going to put a mini sail boat in a big tub of water. we are going to put a big speaker next to the tub and turn on music very loud. do you think this will be successful??? HELP!!
thank you!! )
for moving boat forward (with respect to ground) in water, the medium surrounding the boat (water) must be moved backwards.
---------------------------------------------------------
that is why a huge table fan installed onto a boat can not move the boat forward. because the fan will throw the wind backwards, but water onto which boat is placed can not be moved by the fan
since sound is a longitudinal wave, and it does not require its medium (in which it has to travel) particles to move about in the medium, but vibrate to-and-fro about their mean positions. Thus practically water did not move backwards, so the boat is not obliged to move forward. with each series of wave (ripple) that passes by the boat, boat will rise and fall, and allow the medium to transfer sound energy past it.

Link's most interactive adventure yet.
Have you ever, for a second, envied Link? He saw some awe-inspiring sights by traveling all of the vivid fantasy worlds. Then again he also turned into a wolf in Twilight Princess and attached masks to his face in Majora's Mask that transformed him into some pretty weird beasties.
It's only in Wind Waker that the beautiful blue skies and white beach sands had you dreaming of a similar life. Running after piglets in knee high green grass or jumping into the crisp blue ocean to swim alongside your friends with a rock cliff extending up into bright blue skies. No haste, no stress. How great would that be?
The Legend of Zelda: Phantom Hourglass brings the happy-go-lucky approach to your DS. With this it also brings back the cell shaded graphics that divided audiences back in the Wind Waker days, but there is just no place for a depressed Link on the DS. Nintendo have introduced all manner of new interesting mechanics to account for the DS's abilities. Plodding along between islands takes no more than three minutes at a time as you draw your route on the touch screen. With the technical limitations the DS presents, it is a much more welcome approach than forcing you to trudge your way across Hyrule Field.
While merrily sailing the seas, all manner of beasties bubble up for a piece of Link. The cast of marauders include Rupee-spewing squids, rival ships and one female pirate that seem to be after Link's steamboat Captain Lineback.
To attack these foes is a simple case of tapping them when visible on the touch screen, showing off the stunning explosion - on par with the explosion in Wind Waker. Tap the engine icon and the boat comes to a halt for you to hunt for some treasure on the seabed, in a mine-avoiding mini-game where you make use of a crane to pick the random treasures.
The sailing is action packed, but what it does most importantly is show just how charming the concept is.
An ode to boy and boat; Hourglass champions the spirit of adventure, making it a compelling tale, unlike the all hell breaking loose jumping story of Twilite Princess. With all these new features in the game, what exactly is Link adventuring for this time?
Having dislodged Ganandorf from his throne in Wind Wake, Link is just about to settle down for some well-earned rest when pirate buddy Tetra is nabbed by the phantom ship. Link is thrown overboard and washes up on an island that could save Tetra's life. How convenient? It's also home to the most annoying temple in the Legend of Zelda history – The Ocean King's Temple.
Your ultimate goal is to reach the base of the temple that houses the power necessary to liberate Tetra from the supernatural ship. The temple consists of many, many dungeon-like levels that only become available as you gain more tools on your adventure. Every time you return to the temple, which is unavoidable, you dig deeper with the help of your Hourglass' time which you accumulate by defeating a dungeon boss elsewhere on your map.
While console versions of Zelda can use 3D technology, the humble DS has to make do with lateral 2D arenas. Oh, what's that? The touch screen is a lateral control device? We smell genius brewing. Everything is now controlled via the stylus. Want to smack a troll with a boomerang on his head... around the corner? No problem, just draw a route with your stylus and the boomerang will follow the path and inflict the damage you intend to.
Link's movement in the past on handheld systems have always been a bit dodgy as you really only had the D-Pad for movement, where you can now use the stylus to direct Link in any direction. Drag the stylus further away from Link and he runs; bring it closer to him and he tiptoes his way around a ledge. Tap nearby enemies and Link will slice and dice them.
But it's not just the controls that make Hourglass so special to play; it's the implementation of ideas that works so well. The hookshot, which has virtually been in every Zelda game, is revitalized with some tightrope antics. Nintendo are masters when it comes to reinvention. They find uses for all the DS features - the speakers, the mic and even the hinges (confused? We hope so). It's as if they are showing developers around the world how the DS should be used.
Coming back to the Ocean King's Temple. The constant visits will get very frustrating and having to redo the levels feels like a cheap gimmick to increase the length of the game. The adventure will last you roughly 15 hours, quite short for a Zelda game. This game should be seen from start to finish, if only to witness some of the finest level and puzzle concoctions to grace it. It is one of the best single player titles on the DS, if not the best.
