Begin with a diagram of the system, and definition of directions. Vertically up and clockwise rotations are positive. It must be recalled that in SHM force is proportional to displacement from equqilibriu...
2u-32=53=15, 2u=15+6. Therefore, u=10.5m/s. This is a standard type of question, it is simply about conservation of momentum. Momentum (p) is equal to massvelocity. Initially, the first body ...
When any question requires a formula, it is best to write down what is given to you in symbol form. You can then easily select the relevant equasions from the data sheet. Remember the multipliers! Take fo...
E=1.5MeV = (1.5x10^6)(1.6x10^-19)J = 2.4x10^-13J E=hf, f=E/h = (2.4x10^-13)/(6.63x10^-34)=3.6x10^20Hz
The alternating current flows through the transmitted coil and produces a magnetic field around the coil. (1 mark) When the detector passes over a magnetic object, the magnetic field passes through the ob...
