本試卷包括兩部分,第一部分填空題不需列出過程,第二部分計算題需詳列計 算過程。 一、填空題(計 15 小題,每小題 4 分,共計 60 %) 請按空格號碼次序,以所給的單位將答案寫在答案卷上 1. A meter stick(米尺) balances horizontally on a knife-edge(刀刃) at the 50.0 cm mark. With two 5.00 g coins stacked(堆) over the 12.0 cm mark, the stick is found to balance at the 45.5 cm mark. 1 What is the mass of the meter stick ? ○ g 2. A mass M is split into(分裂成) two parts, m and M-m, which are then separated by a certain distance. What ratio m/M maximizes the magnitude of the gravitational force between the parts ? 2 ○ 3. An office window has dimensions(尺寸) 3.4 m by 2.1 m. As a result of the passage of a storm, the outside air pressure drops to 0.96 atm, but inside the pressure is held at 1.0 atm. What net force 3 pushes out on the window ? ○ N (1 atm = 1.013 × 105 Pa) 4. What is the maximum acceleration of a platform(演講台) that oscillates at amplitude 2.20 cm 4 and frequency 6.60 Hz ? ○ m/s2 5. The speed of a transverse wave(橫波) on a string is 170 m/s when the string tension is 120 N. To 5 what value must the tension be changed to raise the wave speed to 180 m/s ? ○ N 6. A 1.0 W point source emits sound waves isotropically(均向性地). Assuming that the energy of 6 the waves is conserved, find the intensity 1.0 m from the source. ○ W/m2 7. What inductance(電感) must be connected to a 17 pF capacitor in an oscillator capable of(能夠) 7 generating electromagnetic waves of wavelength 550 nm ? ○ H 8. A double-convex lens(雙凸透鏡) is to be made of glass with an index of refraction of 1.5. One surface is to have twice the radius of curvature(曲率半徑) of the other and the focal length is to be 8 60 mm. What is the smaller radius ? ○ mm
