Thx Chadn... By the way, as a cation, does the element with lower electronegativity tend to loose the electrons??? Meanwhile, as an anion, does the element with higher electronegativity tend to accept the electrons?? Albert

????? Any body could helpppppppp??????

????? Any body could helpppppppp??????

So, Swan, Why there is a force exerting perpendicularly from the slope to the object, and a reaction back to the slope??? I think there are no such forces..... Can you tell me why?? Albert

Above is the picture of what I think instead of the picture in the site.... the Fg is the action that first pull every particle of the object downwards.... The slope, having an action on it, gives a reaction back with equal amount of force upwards... Any more explanation towards the topic?? Albert

Any body could help me???

by the way, what is the difference of "active" and "reactive"?? Albert

Yes.... I know there is a table for that.... Does that mean the more reactive element the more willing to give up electrons?? if so, if both elements have same amount of electrons at the outer shell, how do you determine their reactivity?? can we refer this to their electronegativity?? if so, how?? thx for any respond!! Albert

............ I still dont get my question answered..... Ask again!! How can you determine that one cation/anion is more likely to displace the other cation/anion at cathode/anode?? By the way, please also tell me a scientific reason for this determination... thx Albert

why???

Can any body help according to my first post?? thx in advance

Just merely and seriously refers to the topic... Albert

since water are just molecules, why can they have ions?? ALbert

Sorry for duplicating post.... but can any one help me?? about how to determine the ions at cathode/anode?? thx in advance Albert

YT, what do you mean by least likely to be displaced??? Any body can help?? Albert

I just want to ask... How do you determine which ion gives/accepts the electrons if there are more than 1 cations/anions at cathode/anode?? Please do tell me also why..... thx Albert

well, yes, but shouldn't it look like solid??? that's why it is interesting... they are both ionic and molecules representing in water...., but more likely they are mostly molecules, and if there are ions....why we dont get the solid water when we evaporate the molecules?? Albert

I am quite interesting in this.... in water, there are H+ and OH- being attracted by the partial charges of H2O.... but I never see mere Hydrogen Hydroxide.... Why is that??

is the force moving diagonally downwards the resultant force??

I still dont get the principle..... You guys tell me about how to find the force when the plane is inclined... but I want to ask why.... Since gravitational force is first applied on the trolley downwards, the slope at whatever angle, should act with the same amount of force reversely (upwards)... Why the direction is changed??? I never know that g's direction can be diagonal.... I know how to calculate, but I want to know why does this happen.... Maybe a picture with arrows, numbers, and caculations would dexcribe better?? thx in advance Albert

sorry for being not understandable..., but this is my first time dealing with the change of acceleration due to the inclined angle.... This is an useful site: http://lectureonline.cl.msu.edu/~mmp/applist/si/plane.htm but also where I need explanation from... for the red arrow, there is no question, it is the force due to gravity.... but what I dont get are those two black arrows, why the force due to gravity change its direction for those?? I mean, the gravitational force is always downwards, if it can go in those directions, can the gravity force goes upwards direction???? such confuse..... Any body can help?? Albert

But wouldn't building on X86 architecture be better to sell Apples?? there are many hardwares that are compatable with X86... Albert

so what is that vertical acceleration??? is'nt it due to gravity??? During my experiment, I just placed the trolley on a slope, and simply let loose my hand, it went... Albert

By the way, apart from my previous post, why the acceleration from gravity changes due to the inclination angle?? Albert

Then how it differ to my teacher's explanation?? Albert
