I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the...

I can't see how that works pinball ... they still have that massive "double" fur coat .. The only way adaptation would occour (according to evolution theory) is if those intollerant to high temperatures died before reproducing , I don't think there are reports of huskies dying .

Huskies are designed for snow and are much happier at -10 C What I can't understand is how they can tollerate living in houses at +25 C when the only way they can efectivly lose heat is by evaporation from the mouth , why arn't they constantly panting.

Well ... it's only the potential which creates the field ... Imagine the +and - above are terminals of a battery ... once you put a wire across , this channels the "field".

I don't see why the moment of inertia of A comes into it , or it's radius , or mass... The force on B is applied at the point of contact , and it's the inertia of B that resists this force.

Your terminology is not quiet correct ... the electric field is across the two ends of the wire , if it is connected to a battery for example . This electric field (more correctly 'electric potential' ) , created by the battery is from a chemically created excess of electrons at one end. The...

Moisture content of the local atmosphere ...particulates ... dust , sand if the prevailing wind mostly comes from land areas .

This is tricky ... You want fairly high pressure with very low flow ... a squirrel cage CPU cooler might just have enough pressure ,,, (the axial type wont) ... Worth a try ,very compact ...just $2 including delivery eBay will almost certainly work if you make the entry hole about 1cm dia...

I guess 'tall' means dia?? ... In which case we have a radius 0.42 meters We are told the torque is 27Nm which means if the wheel had a radius of 1 meter , it would push horizontally on the ground with a force of 27 Newtons ... and this would be the force accelerating the bike and passenger...

"110/80 R17 wheels ." ... This does not help we need to Know the RADIUS of wheel , including tire.

Have a look on eBay ... a vast array of brushless motors at low prices used for RC .. up to many KW in power (1HP=750W) The 'KV' number indicates how fast ... lower KV lower RPM

From an engineering point of view electric trains seem ridiculous , thousands of Km of HV transmition to maintain , the dangers and losses in resistance ... They surely are unable to compete with diesel electric ... trains which have a diesel generator on-board and use electric transmission to...

So the second regulator feeds into the trigger , which when pulled releases the air , which pushes the slug down the barrel ?? It might be best to start at the barrel end , you know the velocity of the slug exiting the barrel ... , that's the velocity of the air leaving the barrel ... at what...

Well ... if any C particles or CO emitted in exhaust then combustion is not complete , many garages have equipment for measuring emissions, I don't know if this is significant and worth bothering about ... temperature of engine could be measured by thermocouple for comparison . This is a...

Solids are negligibly compressed by pressure ... You maybe thinking of a gun type fission bomb , where an explosive fires a chunk of U235 into another piece to make a sphere of the metal .. this shape has minimal neutron loss so creates criticality with the least mass ... compression is not a...
