comment What planets are visible to the naked eye from Mars?
You can actually see Europa from earth if you block out Jupiter with something. Tricky, but apparently doable - I haven't managed it, but have seen all four moons easily with cheap binoculars.

Doh - yes, moons:-) and yes, you can see them with the naked eye from earth - a few astronomers have reported sighting Callisto and Ganymede. Io and Europa are masked by Jupiter's glare.

Hang on - this definitely means whisky stones are better. We don't want whisky below zero degrees!

Graham, you don't have cold whisky, but you definitely want to make sure it isn't warm.

comment How do whisky stones keep your drink cold?
Interestingly: Soapstone appears to be renowned for its high Specific Heat Capacity: 0.98 J/gK - about 20% greater than other natural stone. It is also incredibly dense and non-porous, which is why it is chosen for whisky stones

comment What's the surface area of a liquid? How does evaporation increase if the surface area of a liquid is increased?
Akanksha - did you mean to comment on your own answer to say it was excellent? I am guessing you meant it to go on one of the other ones. ..

comment How does the energy in a standing wave travel beyond a node?
Key thing is - energy does travel past nodes. Once you understand that, the rest is easy. See Brandon's comment above.

comment How does the energy in a standing wave travel beyond a node?
Remembering my laser optics course at university twenty-something years ago, I would say that skullsinthestars website has a lot of bad physics. Energy does travel past nodes, diffraction is not how dvd players work etc.

comment How does the energy in a standing wave travel beyond a node?
It travels along the whole string and interferes. The frequencies which fit will remain, the others will be rapidly attenuated. Still not sure what the tuning fork has to do with it though.

What has the tuning fork got to do with your question? This seems entirely unrelated. So what is ityou are trying to understand?
