Relationship between period of pendulum and length?
The longer a pendulum is, the more time it takes a pendulum takes to complete a period of time. If a clock is regulated by a pendulum and it runs fast, you can make it run slower by making the pendulum longer. Likewise, if the clock runs slow, you can make your clock run faster by making the pendulum shorter. (What a pendulum actually does is measure the ratio between time and gravity at a particular location, but that is beyond the scope of this answer.)
Will a pendulum clock that is accurate at room temperature of 30 degrees gain or lose time when the temperature increases to 40 degrees celsius?
Virtually all solids expand when they get warmer. Especially in the neighborhood of30° to 40° C, and especially common materials used to construct common householditems.So the pendulum bar or rod ... (I don't know what it's called but I mean the straightrigid thing between the pivot and the weight on the end) ... expands when it warms,and its effective center of mass moves farther from the pivot. This has the effect ofincreasing the period of the pendulum, so the clock runs slower, and "loses time".°
What has two hands a round face always runs but stays in place?
A clock.
How many lemons are needed to run a clock?
2 big juicy runs could make a clock run for 5 month but 2 regular ones would make a clock run for 1 month
What is clock-doubling?
Technology used in microprocessors used to instruct information twice the normal bus speed. The Intel 80486DX2/50 MHz was the first processor with clock-doubling and was capable of running doubled to 50MHz. Today, clock-doubling is not required as the CPU runs independently of the Front Side Bus and connects directly to the North bridge.

A slow running pendulum clock can be sprreded up by?
A slow pendulum clock is sp[eeded up by decreasing the effective length of the pendulum. The weight on the pendulum is usually mounted such that it can be slid up and down the swinging arm. Sliding the weight up slightly decreases the effective length of the pendulum, and slightly increases the rate at which the clock runs. It should be done only in tiny adjustments, because the size of the change might not even be noticeable until a day or two later.
Rosa's family has a grandfather clock with a pendulum The clock is not keeping time correctly because the pendulum is swinging too quickly What could Rosa do to slow down the pendulum swing?
Rosa can adjust the pendulum's length by moving the bob (weight) up towards the base to make it swing slower. This can usually be done by turning a nut or screw located on the bottom of the pendulum. Gradually adjust the length and observe how it affects the swing until the desired speed is achieved.
Why do pendulum-based clocks require weights and springs to operate for extended periods of time?
Pendulum-based clocks require weights or springs to operate for extended periods of time because they provide the necessary energy to keep the pendulum swinging and the gears moving, ensuring accurate timekeeping. Without these energy sources, the clock would stop running once the initial force used to start it runs out.
How can people in good shape have trouble breathing at high altitudes?
At high altitudes, there is less oxygen available in the air, which can cause shortness of breath even in people who are in good physical condition. This is because the body needs more oxygen to function properly in low oxygen environments, and at high altitudes, the heart and lungs have to work harder to deliver enough oxygen to the body.
State two undesirable effects of expansion and contraction and how they can overcome?
One of the greatest advances in timekeeping was obtained by cancelling out the effect of temperature on the pendulum length of a clock. When a clock is warmed the expansion of the metal pendulum makes the clock run slow. Cooler temperatures contract the pendulum and the clock runs fast .John Harrison, a famous 18th century watchmaker, designed a 'Grid Iron' pendulum to counteract the effects of expansion by maintaining the same length regardless of temperature. The alloy metal known as 'Invar' was developed for the balance wheel in mechanical chronometers. This alloy neither expanded nor contracted with temperature making clocks and watches so stable that the determination of a ship's longitude became very reliable. These clocks can be seen in the National Maritime Museum in Gereenwich, London.They are known as H1 to H5 after Harrison and were famously described in the best selling book 'Longitude' by Dava Sobell.

Why should a pendulum be swung less than ten degrees?
The time it takes for a pendulum to make one swing is almost exactly the same regardless if it swings thru any small angle. Once the angle starts getting large, like more then 10 deg, the difference in swing time becomes noticable. If you use a pendulum as a clock,so each second is one swing, then if you start the pendulum swinging at about 10 deg it will continue to be one second per swing even as it runs down to a smaller swing angle.
What has three legs and runs?
a clock
Why does a clock run slower in summer?
A clock doesn't actually run slower in the summer. However, changes in temperature and humidity levels can affect certain types of clocks, such as mechanical clocks, causing them to run slightly faster or slower due to expansion and contraction of materials. It is always a good idea to keep clocks away from direct sunlight and extreme temperature changes to maintain their accuracy.
What nursery rhyme does the mouse run up the clock?
The nursery rhyme where a mouse runs up the clock is called "Hickory Dickory Dock." In the rhyme, the mouse runs up the clock, the clock strikes one, and the mouse runs down.
What runs but never gets out of breath?
A clock, or water.
