※ 引述《darkeyes (囧rz)》之銘言：
: 1.What is magnitude of the free-fall acceleration at a point that is a
: distance 2R above the surface of the Earth, where R is the radius of the
: Earth?
: (A.) 4.8m/s^2 (B) 1.1 m/s^2 (c) 3.3 m/s^2 (D) 2.5m/s^2 (E) 6.5m/s^2
地表附近的g =9.8 m/s^2是怎樣來的?
這題應該只是換個情境而已.
: 2.A torsional pendulum consists of a solid disk( mass=2.0kg, radius=1.0m )
: suspended by a wire attached to a rigid support. The body oscillates about
: the support wire. If the torsion constant is 16N.m.
: What is the angular frequency(in rad/s)?
: A.2 B.4 C.6 D.8 E.7
: 第1題 我同學算B 我算D...不確定哪個是正解..
: 第2題 算不出題目裡的答-_-...
可以看看你的算式嗎?
這題應該很直接...
