The vertical force per unit area pushing down at a height h+dh would be the same, in the absence of gravity, but here it is not, because the force from below must exceed the force from above by the weight of gas in the section between h and h+dh. Now mg is the force of ...

Then we add 2 to both sides to find x = 6 + 2 = 8. 二、物理学科力学基础章节中级难度 The frictional force \(F_f=\mu N\), where \(N = mg\) (m isthe mass and g is the acceleration due to gravity, \(g = 9.8m/s^{2}\)). So \(N=5\times9.8 = 49N\), and \(F_f...
(Atomic Physics) the acceleration of a body falling freely in a vacuum near the surface of the earth in the earth's gravitational field: the standard value is 9.806 65 metres per second per second or 32.174 feet per second per second. Symbol:gAlso called:acceleration due to gravityoraccelera...
