A lighthouse is a structure used to house a light source that acts as an aid to navigation for those at sea. It can also use a sound source for warning. They are also used to warn of dangerous coastlines, reefs, and other hazards, while indicating safe entries to harbors. Most remaining lighthouses are automatic rather than being manned. Questions should relate directly to all aspects regarding lighthouses, including their use and history.

How did the early humans make canoes?

Early humans made canoes two ways, depending on the culture.

1. By burning out the inside of a fallen log and using bone or flint tools to periodically scrape away the burnt wood.

2. By using metal tools to chisel out the inside, and often the outside for a smoother finish. The canoe might then be covered in hot tree sap which, when hard, waterproofs the finished boat

What materials do you need to build a fence on a farm?


Wood and lead wire. Spade to dig hole for concrete or wooden posts, a rammer to make them firm. Steel posts can be driven in with a sledge hammer. Steel wire is then strung along the posts after being tied off at one end. It is stretched or "strained up" tight, then attached to the post using staples and hammer on wooden posts; or threaded through or tied on to concrete or steel posts.

Dont use lead wire, it is too soft, and toxic to stock

They turn the huge light on top of that thing so they can see that there is a big lighthouse there and also so that the ship don't run into any rocks or things like that!!

Tattoos and Body Art

What does a lighthouse tattoo represent?

Lighthouse, as the world sails by.Many things, some folks are just plain attracted to lighthouses....My wife has a collection of about a thousand of the things.....{Course I like them too}

To many a lighthouse represents a new change for the better, a light to the lost or even rescue....To the Christian types they have come to mean salvation.....

To me they are a romantic symbol of yet anther time gone by, and yes, my wife has a lighthouse tattooed on her.....TatuBaron

Well I know that I'm thinking of getting one because my grandma loved them for some reason and both my grandparents died. Their house was the only place I ever felt i belonged and now i dont feel like i belong anywhere but anyways im thinking a lighthouse is where you're supposed to go to be safe from the storms metaphor stuff. It just the idea of a strong home and the place you always go to be safe for me. And of course anyone can connect objects to memories or use objects to represent something in their life.

How far back does a title search go?

A typical "title search" or abstract goes back anywhere from 20 to 60 years depending on the laws and practices in the particular jurisdiction and the complexity involved in a particular matter. A prudent title searcher would certainly go back as far as possible if there is some sort of ambiguity or question.

Most jurisdictions regulate the period that must be covered by a title examination that will be used to certify the title to property. A title examination in the southeast generally goes back 30 years. In Massachusetts the statutory period is 50 years, in Connecticut it is 40 years. Those periods are also stated in title standards promulgated by the real estate bar associations in most jurisdictions. If there is no deed at 30, 40 or 50 years back then the examiner must keep chaining back until an arm's length conveyance is found. A professional title examiner knows how to determine a good starting point then examines the title forward from that point.

The title examination is the key factor in determining whether you will own the land free and clear of all other claims.


Why were lighthouses built?

Mostly for ships at sea so they know where the coast line is.

What is the oldest bar in the US?

The White Horse Tavern in Rhode Island, built in 1673, is the oldest operating tavern in the United States. The Union Oyster House is the oldest restaurant in Boston and the oldest restaurant in continuous service in the U.S. The doors have always been open to diners since 1826.

The oldest continuously operated bar in the United States is Lafitte's Blacksmith Shop in New Orleans. It has been open since 1772. The White Horse has been closed for various lengths of time since its founding.

Math and Arithmetic
Empire State Building

What kind of math is used in physical science?

We basically use calculus(integration,differenciation)and then there's vectors and trignometry. Without maths you cant do physics

The kind of math used in physical science depends on the level of the work. In a high school-level science class, it is likely that nothing more complicated than algebra will be used. However, in many undergraduate classes, at least single-variable calculus is required. Even more advanced classes may require multi-variable calculus or even more complicated math.

Home Electricity

How long does a fluorescent bulb last?

Every once in a while, you will get a dud, but for the most part they are intended to last for up to 10,000 hours. For comparable Lumens, they save about 75% of the energy that a regular filament based incandescent (the regular kind) will use.

Even with the duds, it saves you significant amounts of energy. Get a good bulb, though. You're going to want to like the light quality and a good bulb will last longer. You will save money even if they're giving away the incandescents.

Ideal conditions for a compact fluorescent bulb (CFL) are when the bulb comes on, has a chance to warm up, and then stays on. Closet lights will burn out sooner (per hour of use, but since they're used so less frequently), but you will still save energy.

Modern bulbs come on instantly, but they take about 30 seconds to heat up.

Best of luck!

How does a zener diode work?

A zener diode is designed to be operated in reverse bias, and have a specified breakdown voltage. For example, if you wanted a part that is supposed to get 10V applied to it, and you only have a 12V rail, you can put a resistor and a 10V zener diode in series, and the zener diode will make sure that only 10V get dropped across it. Any more and it will begin conducting.

It will draw enough current to drop the excess voltage across the series resistor. If the load on the output terminals increases, tending to reduce the output voltage, the Zener just takes less current. The idea is that the total current through the series resistor is enough to stabilise the output at 10V.

ANSWER: A zener is a diode that has the property that when reversed bias is applied to exibit a breakdown of a voltage with a sharp knee. This property can be used as a regulator since the voltage will not change it the current trough the zener changes.


Who invented lighthouses?

The first lighthouses could be said to be those of ancient times when fires were set along waters' edges to warn boats about rocky and dangerous reefs and shorelines. The Egyptians were actually the first group of people to build a lighthouse, complete with wick lamps for light. Between 285 and 247 BC, the Egyptians completed the tallest lighthouse ever built. It was believed to be up to 660 feet tall and lasted for over 1,500 years. This was the famous "Pharos", or Lighthouse of Alexandria, and one of the wonders of the ancient world. Other early builders of lighthouses were the Phoenicians, Greeks, and the Romans.
