what is absolute uncertainty? Is it the uncertainty not multiplied by 100? like a reading on a meter rule is 5 cm so absolute uncertainty is 0.1/5 na? and % uncertainty is 0.1/5 *100 ? Am i correct?
yes u r rite!

slide left to right to get either zero resistance or 100 percent resistancecan any1 tell me how to use variable resistor??
Not sure about that! As far as I know, you dont have to change the height. Just the distance from which you're dropping the ball!Exactly ,confirmed. Basically the height of the slope is to be changed.
I hate electricity practicals blah. I'm really hoping somehow first question doesn't even have a graph.
Has it ever happened that a electricity part didn't have a graph?
alrite guys...finaly here it is..!
two questions....one electcial other mechanical... electricity one will consist of -Variable Resistor, switch, battery, a sample wire, connecting wires, an ammeter and voltmeter...u willhave to measure the V & I after setting the apparatus after changing resistance of the rheostat on the variable and make a graph using the values....
while the second one has a clamp stand, a marble, stopwatch...u need to slide down a ball from a certain height, note the time.....
simple eh?
Could be the case. Atleast the instruments are confirmedNot sure about that! As far as I know, you dont have to change the height. Just the distance from which you're dropping the ball!
isn't the least count of a meter rule 0.1 mm, which is 0.01 cm and thus uncertainty = 0.005/calculated-value ?yes u r rite!
itz neva tht complicated dude....do you have to find the value of the resistance of that wire.. ?
lol it wont be complicated ... we just have to do what the instructions says and in the end gradient or something will give the resistance of the wires..itz neva tht complicated dude....
Anything on Physics 31 please?Okay guys.
Physics 33 Tomorrow will have an electricity experiment. And another simple one.
The electricity one will consist of -Variable Resistor, switch, battery, a sample wire, connecting wires, an ammeter and voltmeter. You`d have to measure the V & I after setting the apparatus after changing placing of the rheostat on the variable and most probably make a graph.
The second one has a clamp stand, a banta ( I dunno whats that called in english ). stopwatch. And you need to slide down a ball from a certain height, note the time.
Note : These are not the confirm experiments. However these instruments are confirmed, and probably the experiments will be somewhat the same as above. Don`t ask about the validity, for sure these will be there tomorrow.
i cant say anything bout tht thou?lol it wont be complicated ... we just have to do what the instructions says and in the end gradient or something will give the resistance of the wires..
