Study Design 2009-2014 erratum

As published in the VCAA Bulletin, March 2008, p.9.

Teachers are advised that

1. On page 27, Unit 3: The second sentence in the second paragraph should not refer to ‘at least two independent, continuous variables’.
   The sentence should read:
   • They design and carry out an extended practical investigation.
2. On page 37, Unit 4, Area of Study 1, Electric power, the second dot point is incomplete.
   The dot point should read:
   • calculate magnitudes, including determining the directions of, and magnetic forces on, current carrying wires, using F = nIℓB where the directions of I and B are either perpendicular or parallel to each other;
3. On page 40, Unit 4 Area of Study 3, Detailed Study 3.1: Synchrotron and its applications, the equation at the end of sixth dot point in the Key Knowledge is incorrect and should be qvB = mv²/r.
   The dot point should read:
   • calculate the radius of the path followed by a low-velocity electron in a magnetic field, qvB = mv²/r.
4. On page 31, Unit 3, Detailed study 3.1: Einstein’s special relativity, the equation in the last dot point is incorrect and should be m = m_oγ.
   The dot point should read:
   • explain the impossibility of motion faster than light in terms of relativistic mass m = m_oγ at speeds approaching c.
