What is the actual pressure at a depth of 125 m in a dam? State your answer in m H. O and pascal.
[Atmospheric pressure = 10.3 m H2O, density of water, p = 1 000 kg m and
gravitational acceleration, g = 9.81 m s]​

Which is not true about oxygen-17 and oxygen-18?

Along the line connecting the two charges, at what distance from the charge q1 is the total electric field from the two charges zero? express your answer in terms of some or all of the variables s, q1, q2 and k =14ï€ïµ0. if your answer is difficult to enter, consider simplifying it, as it can be made relatively simple with some work.

The atoms in a nickel crystal vibrate as harmonic oscillators with an angular frequency of 2.3 × 1013 rad/s. the mass of a nickel atom is 9.75 × 10-26 kg. what is the difference in energy between adjacent vibrational energy levels of nickel? (h = 6.626 × 10-34 j • s, , 1 ev = 1.60 × 10-19 j)
