正文 第八十四章 熊又是什么颜色的熊(第1页/共3页)
物理月考卷子前面的题目都是应试范围内的,在秦克眼里没什么难度,他斩瓜切菜般,在十分钟不到的时间内就做完了。
但最后那道明显是额外为自己准备、要考究自己的附加卷题目,让秦克有点头疼。
他揉揉额角的太阳穴,这是什么怪题目?你确定你出的是物理题?
“附加题:夏国时间十月的一天,一只熊掉落猎人专门为它而设的陷阱中,现在知道这个陷坑深19.6124米,下落时间正好2秒,请回答,猎人最可能是哪个大洲的人?熊又是什么颜色的熊?”
秦克心里吐槽不已,这么深的大坑,猎人用什么来挖?熊掉下去了几乎是挂定了,你猎人又怎么将笨重的熊拉起来?如果全由一个人纯手工操作,这工作量加起来怕都超过一只熊的价值了!
但显然题目没让他解决这些让人吐槽的问题,而是问猎人的出身,熊的颜色。
物理考试居然还和地理、生物联动了?
秦克咬着笔头沉思。
他用心算都能轻易就根据h=1/2gt2,计算出g=9.8062,这明显不是北极的9.832,也不是赤道的9.780,那可以排除北极熊,只能是在南北半球范围的中间区域。
由g=9.7803 m/s (ψ为纬度)
计算出纬度ψ为45°,即南纬45度或者北纬45度。
秦克努力回忆了一下,余下熊的种类大概就南半球的眼镜熊,北半球的棕熊、黑熊、黑棕色的马来熊。
会挖这么深的坑,不可能对付小体型的熊,所以眼镜熊和马来熊的概率不大。
只剩下棕熊和黑熊。
根据生物分布地理图,棕熊主要栖息在寒温带针叶林,也就是北纬50°~65°之间,与计算出来的45°不符,而且寒温带地表太硬,无法挖深坑。
黑熊的分布则更广泛,从低海拔的热带雨林到亚热带的常绿阔叶林、河谷灌林丛,温带落叶阔叶林、针叶林以及山地寒温带暗针叶林等林间环境都有栖息,而且它们还有垂直迁徙的习惯,夏天时的主要栖息地在较高的山林,入冬前却会高地逐渐转移到海拔较低处的河谷。
十月正是入冬前,极可能是黑熊下山后中了陷阱。
何况陷阱能挖到19.6124米,土质一定是较软的冲击母质,才易于挖掘,河谷地形最为符合条件。
况且黑熊也称熊瞎子,视力不行,中陷阱可能性大。
另外再从经济的角度来考虑,一般的熊掌、熊胆都主要取自攻击性没棕熊那么强的黑熊。
