nothing can be to the rightt either upwards or downwardsi drew the arrow downwards, and the force right side to the side of paper!

yawhat formula u used for this value? sin i/ sin r?
Angle of incidence= 30 degrees
Me tooi got 42
thats wrong! we had to use sin r/ sin i, it said from water to air!
how?but remember thet angle in air is always greater then in meduim so it wont work

Right, so 42 is greater than 30. 22 is not :B)but remember that angle in air is always greater than in meduim so it wont work
There's no one giving Variant2 now. One'd think YOU're the BIG all-in-all autho.You guys are cruel. You know Xtremepapers is pretty popular and the authorities could have it pulled down... can't you just wait for a few more hours before discussion?
Mass of half the bottle= 1.30-1.90
