Actually i made a mistake with the Vfinal expression. My new answer is B= 5.3 x 10^(8)

Homework Statement A rock at the surface has a density of 2600kg(m^(-3) 90000m down its density is 3100kg(m^(-3) Change in pressure at the depth is due to hydrostatic pressure. Whats the bulk modulus of the rock? Homework Equations Δp=p + ƿgh Δp=-B(ΔV/V) The Attempt at a...

Hi yes that was my question thanks, But why is that a different formula than the one used to calculate the moons influence on tides?

Hi , How could I calculate the acceleration of an object on the Earth's surface , say at the equator , from the influence of the moon , when the moon is directly overhead? I have calculated the force of attraction from the moon to be 1.99 x 10^(20) N. Now to find the gravitaional...

Thanks that does help, but I am still puzzled on how to determine the cartesian coordinates (x,y,z) , for the rotating reference frame ? any ideas please?

Can somebody please explain ( properly)with examples , how the right hand rule describes the direction of coriolis acceleration? please!

Hi what type of calculation errors should i do for my data on the capacitance discharge experiment. I had a voltage of 1.5V ,and I know the resistance, so the aim was to obtain the value of the capacitor, using the time constant RC=t formula. I done 4 trials , with the same voltage, (...
