why pendulum clocks dont work at sea
so you dont get stuck out at sea when the tide comes in you dummy
whyy dont yuu go somewhere with a beach early in the mornning LOL
well it moves the tides, so if your work involved the sea it would be affected.
it used thick metal and glass to observe deap sea wild life and measure the ocean floor
To me, calm, like the sea. The sea is calm, sea is blue, blue is calm. :)
..weigh less and the pendulum will swing at a slower rate. It might become more valuable (high mountain areas have less access to fine clocks than many sea level communities).
There were only clocks prior to John Harrison's invention of the "Sea Clock". It was invented to find your current longitude on the earth used for ships at sea. Regular Clocks which used a pendulum were too susceptible to movement, humidity and temerpature for reliability until Harrison's invention of a balance spring and escapement which replaced the pendulum. Later Harrison miniaturized his Sea Clock which resulted in better accuracy and reliability into what is now known as a pocket watch.
It's faster at sea level and slower at the top of a mountain.
Denser, heavier air.
The Earth spins at a precise and known speed. If we use a sextant to observe the height of the Sun above the horizon and note the precise time when it is highest - when it stops going up and starts going back down, at "Local Apparent Noon" - we can look up the Sun's location in our Nautical Almanac and very easily calculate both our latitude and longitude. However, this requires an ACCURATE clock, and in the 1600s and early 1700s, no such clock existed. Oh, there were lots of fairly good clocks, but they were all pendulum clocks - and the one thing you cannot use on a ship at sea is a pendulum clock! The British Royal Navy offered a standing prize for the developer of an accurate spring-driven clock that could be used at sea.
Has anyone really been far as decided to use even go want to do look more like a hammer in the clock pendulum sea saw?
Early sailors used the sun and constellations to fix longitude and latitude before they had clocks. In 1761, John Harrison designed and built a "sea watch" that was accurate to 25 seconds in a trip across the Atlantic. The problem was the change in temperature, pressure and humidity as the ships sailed.
As the force of gravity increases the period would decrease. So shortest period on the sun (if you can keep it intact), then sea level, then mountain top and then moon.
i dont see the sea
Well you should sit down and talk to her. If things dont work u than just dont worry. There are other fish in the sea. But only 1 is for you.

A deep sea submersible is a type of machine and I dont really know how it works but I Do know that my msn is cheesey_jasmine@hotmail.com if you want to add me go ahead i add everyone
