if you roll a quartz ball into another quartz ball...
If you roll a quartz ball into a stationary quartz ball what would happen to any electrical energy in the collision? My guess is that the structures would need to be in perfect alignment for any meaningful electrical energy transfer and any...
so 90kg x 9.8ms x 4.4ms x 0.17 (sin10deg) = 659.7 joule sec which = 659.7 watts.
its the combination of unfamiliar units and algebra not to mention the silly mistake not converting the kph that was the problem. i was pretty sure 2000+ watts was too much but couldn't see wood for the trees...
got it i think, its the units that I am unsure of but:
90kg x 9.8ms gravity x 16 kph x 10 degrees = power needed of 141,120 joule/min or 2352 watts.
my issue was 141120 looked ridiculous to me and i had to work out what i was missing. hopefully I am right thanks to chrisbaird for not...
thanks, think i must have been dropped on my head as a baby... i was aware of the weight/mass difference but not pounds / kg. think I am having a bad day, any chance you could do an example equation with numbers that i can follow from start to finish? i don't want to waste your time for too...
i apologise for having such a base level of knowledge, luckily i have the sense to use the same measurement system, and to check that if i get a silly result. 200 pounds is 90.7kg and m/s squared i thought was acceleration. in an effort to help myself I am looking for just a constant speed so...
im fine with assuming 100% efficiency, so 130kg x 16kph x 20 degrees = power? 41600, joules? i swear I am not deliberately being dumb! I am the poster boy for those who spent school looking out the window only to need to relearn it all later in life. if I am right the end result is in joules?
i failed science at school and often want answers to q's thank God for pf!
i want a nice easy way to work out how much power you would need to climb hills: power versus weight and gradient is what I am after. assume constant speed constant gradient ignore wind resistance. I am after simple ball...
i didnt have time to read every post in this thread but wanted to share my experience. several years ago i was on the m25 (large very busy freeway in england) in light rain with the sun to my right when the traffic slowed, then the light seemed to take on a red,orange, yellow etc tinge about as...
hi, if you had a litre container full of water with negligible air and nothing else and heated it at a linear rate from 50 degrees centigrade upto 200 degrees centigrade does the steam pressure rise linearly or exponentially?
the measurements are plucked from the air, its the rate of steam...
thanks guys, was daydreaming about compressed air energy storage with the ability to ignite the mix as a power boost. Lots of time to daydream as I am a trucker. Thanks
can you delay autoignition of petrol air mixture by preventing it from heating above 20 degree celsius as its compressed. how high pressure could be reached before autoignition? assume 10 to 1 (10:1) air to petrol mix.
