Which direction must the string run for the sundial to work properly? Which direction must the string run for the sundial to work properly?
To learn how to tell time on a sundial, one must understand how the shadow cast by the sun moves around the dial. The shadow will indicate the time based on the position of the sun in the sky. By observing the direction and length of the shadow, one can determine the approximate time of day. Practice and observation are key to mastering the art of reading time on a sundial.
A rainbow must always be in the opposite direction from you compared to the sun. So if you see a rainbow in the morning, its center would be in a generally westerly direction from you.

because they both rotate. If you hold the string with your and swing the ball around, the ball going around your hand is like a planet going around its star.
Clocks are timekeeping devices everyone is familiar with, and it is easy to take their ability to show their users the exact time down to the second. However, at one time, clocks weren’t nearly as sophisticated, and didn’t even use the same principles as today’s timepieces. The sundial was one of the first clocks that was used by many people. By looking at the shadow cast by a sundial’s “styleâ€� – a rod or straightedge that projects from the surface of the sundial. To work properly, the style has to be pointed towards true North, and the angle it has compared to the horizontal surface must be adjusted for the latitude of its location. The biggest hitch is that the Earth doesn’t rotate at a perfectly constant speed. This can throw off sundial time by as much as 15 minutes. Also, sundials show the local solar time unless compensations are made to bring them in line with clock time. Keeping up with Daylight Savings Time changes would require a further realignment of the sundial. It is no wonder that people kept looking for another kind of clock, given the drawbacks of using sundials. Mechanical clocks had the promise of being able to keep accurate time regardless of the sun’s position, as well as working during all 24 hours instead of just during the day. At first, however, mechanical clocks weren’t very accurate or reliable. Therefore, people would still arrange meetings and other events by using terms like “around lunchtimeâ€� instead of trying for specific times. As technology improved, the ability to accurately track hours, and then minutes, became standard. These clocks, powered by springs, first appeared in the 1400s. Clockmakers then worked on various mechanisms to allow them to keep time at a constant rate, even as the spring relaxed. One big development in clock design was the basic concept of using an oscillating mechanism to tick off the increments. This allowed clocks to be much more accurate and reliable. This development, along with other continual advances in design, have made clocks such a workable method for telling time that it’s hard to imagine a society without them.
The direction the sun is in!!! and you are soooo from Macleran's class -Sarah
The gnomon must be facing north and the base must be level
You can make a sundial with some very simple materials. Click on "Add Related Links" to see specific instructions.
A wind vane must be located in an open space such as a roof of a building but with very few obstructions. Open space makes sure that the wind direction and any changes in the wind direction are accurately recorded.
Yes, but it would be difficult, as the markings on a sundial must firstly be measured very accurately (the markings are not evenly spaced) and tend not to show particularly low figures. However, theoretically, it would be possible - just find an accurate enough sundial.
A numeric string.
The synchroscope must be moving clockwise to indicate that the generator frequency is slightly higher than the system frequency. This ensures that when the breaker is closed, the two frequencies will synchronize properly.
You must pluck the A string to get the pizzicato A.
In such a direction that it is not 'standing into danger'.
They must be properly sized for the intended wearer
You must receive the Eucharist properly because it is a solemn and ancient religious ritual, and if you do not do it properly you would be showing disrespect to that tradition.
Through the string connecting the cans. This string must be kept under tension at all times for the device to operate. Therefor the two cans must be on a direct line of sight with no obstructions to interfere with the string.
