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

定積分の計算で∫∂/∂x～～～dxというような形の式があるのですが、この場合 ∂/∂xがあるので先に～～～の部分をxで微分してからxで定積分するということでしょうか。

This assumption may be valid because the air column being considered is deeper than the nocturnal turbulent boundary layer. QE is the latent heat flux which is released into the air column with the phase change of water vapor. When there is no phase change of water vapor, QE=0. QR is the heat flux of the long wave radiation and defined by QR=pC * a 0z where (30 /a1), s the warming rate of air due to convergence of long wave radiation, L t(z) and L(2) are the upward and downward long wave radiation at a height of z respectively. Among several kinds of calculation methods for long wave radiation (Stephens, 1984), formulae
