godfather93:
can someone please brief me on the properties of shapes (kite, rhombus, square, rectangle, parallelogram, trapezium)
It's extremely urgent!!
Thanks

astarmathsandphysics:
Square - equal sides, angles. roational symmetry 4, lines symmetry 4
Rectangle  2 pairs equal paralell  sides, all equal angles. roational symmetry 2, lines symmetry 2
 rhombus all equal sides, 2 paralell pairs, 2 pairs equal angles. roational symmetry 2, lines symmetry 2
 kite 2 pairs equal sides, 1 pair equal angles. roational symmetry 0, lines symmetry 2
paralellogram 2 pairs equal paralell sides, 2 pairs angles. roational symmetry 2, lines symmetry 0
Trapexium 1 pair paralell sides. In general no lines symmetry, no roational symmetry or equal angles

Must leanrn how to draw a table for posts like this

thanks astar!! :D ;) ;D

this question confuses me (physics)
it's question 1 (the paper is attached). the markscheme gives no clear answer.

sweetsh:
You have to take readings they are easy =O
a) 0.65A -1.65V
the mass you calculate it by subtracting: 6.58-3.26=3.32g
the volume is 150cm3
the gap between electrodes is 0.8 cm
b)to overcome this problem take the electrodes out of the beaker carefully without changing the length of gap and then measure it by a ruler
c)for me i will answer the -temprature-
