4. A simple accelerometer can be made froma U-tube containing water as in 200mm Figure. 1) When the acceleration of a car with the U-tube is a [m/s?] in the horizontal direction (x-direction), find the relation between a and the level difference h [m]. 2) When H vertical tubes at a = 0 is 250 mm, find the maximum accelaration which h = 400 mm and the water level ho for both H h。 can be measured by this accelarometer. Use g = 9.8 m/s? and pwater = 1000 kg/m?. y water x

Earth has two sets of poles: the geographic poles and the magnetic poles. The geographic poles are located at the northemmost and southernmost ends of the earth. The location of the magnetic poles, on the other hand, are ( ア ) moving, This fact has several implications for navigation and transportation. Shifts in the position of the North Magnetic Pole are nothing new. Since 1831, scientists have been tracking its location. The movements are caused by changes in the flow of swirling molten iron in the earth's core which affect how the earth's magnetic field behaves. What is surprising to scientists is the speed at which the pole has been moving in recent years. For most of the 20th century, magnetic north was located around the northern parts of Canada. It drifted around, moving slowly north at an ( イ ) speed of approximately 10 kilometers per year. In recent decades, that rate has increased significantly to about 55 kilometers per year. The North Magnetic Pole is now moving away from Canada toward eastem Russia. While scientists can't fully explain how changes in the carth's molten core are affecting the pole's movement, they can map the earth's magnetic field. Doing so allows them to ( ウ) hé rate of change over time. This, in turn, provides information on how the magnetic field may shift in the future. Information on changes to the earth's magnetic field is used to produce the World Magnetic Model (WMM). This model is used as the basis for all fornms of modern navigation, from how ships move at sea to mapping software in smartphones.

The model is updated every five years, but in 2018, during routine checks of the 2015- 2020 model cycle, scientists noticed a problem. Because of the rapidly shifting pole, the WMM was close to being outside the acceptable limits for navigational errors. This forced the release of an updated version of the model、 It was revised ( オ ) in 2020, and the current version is expected to last until 2024, As well as keeping track of the WMM's accuracy, scientists continue investigating why the magnetic field is changing so dramatically.
