兩條物理/力學問題，請指教！

1.d 試管在向下時 , 管內空氣始終會被水壓施力而減少了一些體積 ,
管內空氣體積減了會造成壓力增加以抵抗大氣壓力把水壓進試管 ,
而管內空氣始終會縮減了一些很難用眼去看到的體積, 所以系d

2 c 無論圖1和圖2 , 人向上運動要的力都只和自己的重量有關
而圖1和圖2 的人重量一樣 , 所以付出的力量是一樣 ,

1. I suppose the test-tube is inserted into the water in a inverted position (i.e. bottom up).The, the answer is option DReason: water pressure compressed the air inside the test-tube until it is at the same pressure as that at the depth of the mouth of the test tube.
2. I would choose daugram 2.Reason: the increase of potential energy of the body is smaller in diagram (2) than in diagram (1), as the body is already at a higher height at the beginning. The work done to raise the body is thus smaller.
