Physics nd bio atp tips needed??

[Talha]

can any 1 tell me the general answers to physics nd bio atp ques. like the one askng :

wat r the precautions for the experiment?
hw can u improve the experiment?
wat is the relationship between two quantities? etc etc etc

For Physics:
Repeat the experiment a couple of times, ignore values with huge differences and plot a graph with a line of best fit.
Avoid 'Parallax error' by getting eye level perpendicular to the scale.
Avoid zero error when using instruments like 'Vernier Calipers' or 'Micrometer Screw Gauge'.
When measuring distances, use set squares perpendicular to point and then use a rule to measure distance.
Depending on experiment, turning off fans and closing windows might improve experiment results.
When involving electricity, use high voltage supply, clean contact & use continuously variable supply.

For Biology:
Wash the apparatus with distilled water followed by the chemical you'll be using.
When taking readings, avoid 'Parallax error' by getting eye level perpendicular to the scale.
Repeat the experiment a couple of times, ignore values with huge differences and plot a graph with a line of best fit.
Depending on experiment, turning off fans and closing windows might improve experiment results.

And these are just a few..

always use



C----control


O----organism


R----repetition and record


M----measurements


S----scale
