Hey I need help with 0625_s14_qp_32.pdf question 3B physics :D
That is Easy ! Look
Gravitational Potential energy = Mass x gravitational accelaration x Height

So, According to question

G.PE is 16.2 Joules
Mass is 2.0 kg
Gravitational Accelaration is = 10

16.2=2.0 x 10 x Height
16.2= 20 x height
16.2/20 = Height
Height = 0.81 meters

Hope you understand ! If you do have Any doubt feel free to ask

Hi!
I understand this example is talking about dilution... But I haven't really understood the math and the figures used. The conversion of units.
It would be immense if someone could help me out with this!

Thanks...
