c ur t value is 4 sf so if u square it although u get till 5sf but u only ryt down 4sf cuz thts the no. of minimum significant is the raw values

Thank You

anytym ;)

neno:
uncertainity of an angle is 1/value(degrees)
uncertainty of redaing from a ruler is 0.1/value(cm)
uncertainity from a micrometerscrew guage is 0.01/value(mm)
uncertainity from a venier calliper is 0.01/value(cm)
uncertainity of time is 0.01/value(seconds)

is this all correct can sum1 check ??

neno:
and another question in a table of reading do all the readings have to be the same sf or only the entire group nd the groups related with it(like t and tsq shud have the same sf or like even the distance measured for tht time also has to be the same sf??)
