Sounds travel through solids "best" in that the sound wave moves very quickly. However, it also takes more energy to vibrate a solid object,... Learn more about this topic: Sound Energy: Lesson for Kids from Chapter 6/ Lesson 42
For more than a century, scientists have proposed the idea of using the pressure of sound waves to make objects float in the air. As sound waves travel, they produce changes in the air pressure — squishing some air molecules together and pushing others apart. ...
We’re still playing the game, but we thought I’d jot a few notes down before we forget. First, it’s so refreshing to play a hidden object game where it takes some time and effort to find the objects — that’s the most enjoyable thing about this game for us, aside from the po...
yeah, that's a hard one. It's not possible with just constructor calls, that's for sure. Something needs to gets instantiated first and then accept it doesn't have any instances of the other object yet. I'm guessing that as a static inner class builders have access to the fields of ...
Would the object cast a shadow? Would that shadow be visible in the reflections? Or refract in case? And would the reflection of the refraction be visible? Objects behind the non reflected, but refractive object, would be bent? It seems a fairly odd thing to ask a pure...
2002). These sorts of characteristics of the cognitive agent likely produce individual differences in aesthetic preference. Most modern analyses of aesthetics suggest that aesthetics emerge from a dynamic interaction between the cognitive agent and the object, rather than solely from explicit ‘objective...
ferry revellers to and from the site.If even attending sounds too likely to be dirty and/or loud, you can just watch on the caravan's flatscreen hi-def TV, sit back and play PlayStation, listen to your iPod through the supplied dock - or dig into local produce from the campsite ...
1. The forgetting curve shows that we forget things easily, so we should help our audience remember our speech as much as possible. 2. Always remember public speaking is about “what you say”, and “how much your audience can remember” what you say. 5. 舞台表现力 I. What Is De...
Commands that controlled an actuator based on this algorithm would produce a force proportional to the user object's motion to simulate movement through a fluid. Movement in other mediums, such as on a bumpy surface, on an inclined plane, etc., can be simulated in a similar fashion using ...
it is expected that a genuine banknote will produce relatively low responses from both photosensors. Accordingly, if the comparators 142 and 152 compare their inputs with a simple threshold, the logic gate 146 may be arranged to produce an output only if each input indicates that the respective...
