FLYTEK飛行員－物理小試身手

：嘿，準機師們❗️
還記得培訓機師『筆試』當中，數理扮演了相當重要的腳色嗎？

通常困難程度會介於國三至高一之間，然而每家航空公司的難度又有所差異~像是長榮的數理困難程度是大家有目共睹的（50題，只有60分鐘作答！）

不過別擔心！今天FLYTEK準備了3題『物理題』來讓準機師們小試身手呦‼️

趕快來看看能答對幾題吧！

❶ Two solid spheres of radius R made of the same type of steel are placed in contact, as shown in the figures above. The magnitude of the gravitational force that they exert on each other is F1.
When two other solid spheres of radius 3R made of this steel are placed in contact, what is the magnitude of the gravitational force that they exert on each other?
(A) F1
(B) 3F1
(C) 9F1
(D) 81F1

❷ The figure above shows three resistors connected in a circuit with a battery. Which of the following correctly ranks the energy E dissipated in the three resistors during a given time interval?
(A) E300Ω > E200Ω > E100Ω
(B) E300Ω > E100Ω > E200Ω
(C) E200Ω > E300Ω > E100Ω
(D) E200Ω > E100Ω > E300Ω

❸ A person driving a car suddenly applies the brakes. The car takes 4 s to come to rest while traveling 20 m at constant acceleration. Can the speed of the car immediately before the brakes were applied be determined without first determining the car‘s acceleration?
(A) Yes, by dividing the distance (20 m) by the time (4 s).
(B) Yes, by determining the average speed while braking and doubling it.
(C) No, because the acceleration is needed to use standard equations such as ∆x = v0t + 1/2at^2 .
(D) No, because the fundamental relationship that defines velocity contains acceleration.
