광전효과(光電效果 photoelectric effect): 물질이 빛을 흡수하여 자유전자(전도전자 포함)를 생성하는 현상. 또는 이에 따라 전기전도도가 증가하여 기전력이 나타나는 효과이다. 여기서 생긴 자유전자를 광전자라 한다. 원자 등에서 광전자가 방출되는 광이온화, 고체 표면에서 광전자가 방출되는 외부광전효과, 절연체나 반도체 등의 전도전자 증가에 따라 전기전도도가 증가하는 내부광전효과(광전도), 경계면에 기전력이 나타나는 광기전력효과 등이 있다. 일반적으로 외부광전효과를 말할 때가 많다.
I'm sorry, all of you are wrong. It is true that ice is less dense than liquid water: it is most dense at 4 degrees C. However, please read the explanation and the link: a floating object (which ice does) displaces its MASS in liquid, not it's volume. because the melted ice cube has the same mass (i.e. same number of molecules) as when it was frozen, it will take up the same amount of space in the glass. you would be correct that the glass would overflow if the ice had been pushed down and submerged (because submerged objects displace their VOLUME). is that clear?
It sure is clear. Though it already was with the explanation under the question only. Very interesting question anyway. Simple answers, requiring some reflexion though.
Your question was would you weigh less if the moon was full but the answer talks about your weight *on* the moon. It's too bad we can't fix questions that are incorrect...
I'm sorry Sam, but this one is not entirely right. It might seem so, if you consider the earth as a point-mass, as is often done for the sake of simplicity, which renders your question a bit moot. Both earth and the baseball considered a point mass, there will be no difference.
However, in reality each particle exerts a gravitational pull on the space station. The center of mass and mass is the same in both scenarios, however the distance from each particle changes. I haven't done the math to check if this is correct, but your question is not as simple as it appears. I suspect that due to squared inverse relation of distance, that resultant force of the baseball will be less than that of Earth.
To clarify that should be "... only on the center of mass and the distance ..." since the baseball would have the same center of mass as the earth (both round) the space station would be AOK.
