ERRATA

We've found a couple few more of errors in the text.

Chapter 1, p11: Subheading "Further Examples" (a) should be "radius of the Sun". Thank you to Joshua Noronha, St. Laurences College, Brisbane.

Chapter 2, p33: 4th line from bottom. Answer to final part of example should be negative (-3.3 m s-1). Credit to Michael Schobbe, Year 11, Caboolture SHS.

Chapter 2, p37 and p41. Table 2.7: the last column should have units for acceleration as ms-2. Same for acceleration in Table 2.10 p41. My thanks to students of Richard Baker, E-Learning Leader, St Stephen's Catholic College, Mareeba, Qld.

Chapter 2, p50, Q37d. The correct answer is 715 km not 715 m. It was just a typo. My thanks to eagle eyed student Caitlin Ramsay in my Year 11 class at Moreton Bay College.

Chapter 2, p50, Q37f. The correct answer is 53846 hours not 55846. It was just a typo. My thanks to student Joshua Napier in Grade 11 at Meridan State College.

Chapter 2, p 50, Q40 about Brett Lee. Answer is 20 ÷ (157.4 ×1000/(60×60) = 0.46 s not 0.55 s as stated on p761. Credit to Alyssa Young, Year 11, Caboolture SHS.

Chapter 2, p50,Q46(a) about the skateboard. The answer should be a displacement of 225 m (area = 38 x 15/2 - 12x10/2 = 285 - 60 = 225 m). I misread the question and worked out the time for 60s NOT 50s as required. My thanks to Kristoff Todd, Physics Teacher, Parklands Christian College, Park Ridge, Qld, and to Michael Leask and his students Joseph Weyer and Ryan Weston from Meridan State College. The answer for Q46(b) is probably closer to 395 m than 392.5. The line actually crosses the x-axis at 38 s not 37s as I originally worked out. Not that Q46(b) asks for DISTANCE not displacement.

Chapter 3, p57: Lines 4 & 5 should read "...but is heading north-west." Spotted by Michael Leask.

Chapter 3, p 60. The answer to Q4 should say that "height" is a vector (not a scalar) at it indicates direction as well as magnitude. Thank you to Michael Leask, Caboolture SHS

Chapter 4, Q20: Answer should be (a) (i) 3.04 m s-2; (ii) T = 104 N

Chapter 4, Q49: The angle was wrong. the answer is: Using trigonometry: the wind force FH = FW tan 37° = 2.26 x 10-3 N. Thank you to Bryan Corcoran for his eagle eye.

Chapter 4, Q59: Answer should be 15.3 m s-1 (see worked solutions web page).

Chapter 4, Q61: Answer is 953 N. Thank you to Brianna Towers for finding this.

Chapter 4, p56-57. Physics teacher Rowan Barber points out: Looking at the example on the bottom of page 66 and the top of page 67 of New Century Senior Physics (2004) I am actually not sure how you got s= 37m for part (f). If one reads off the graph it looks like s = 40m, when t =15s. However if one substitutes t = 15s into the equation of best fit, s = 1.7t +16 s = 1.7 x 15 + 16 s = 25.5 + 16 s = 41.5 m. My response to Rowan (besides thanking him) is: "I think the question probably asked for the displacement at 12.5 s but a typo made it 15.0 s."

Chapter 4, p76. Q1(c) should be N22°W; Q1(d) should be S18°W. My thanks to Gaetano Caputa for alerting me to this.

Chapter 5, p112: Novel Challenge. The Acapulco cliff diver landed 5 m from the base of the cliff, not 5 mm. Thank you to Joshua Noronha, St. Laurence's College, Brisbane.

Chapter 5, p 114. Activity 5.3.  (a) should read Horizontal range sh= u cos θ × t = R; velocity at maximum vertical height vv = u sin θ + at/2 = 0. Thanks to Rod Duncan for pointing that out.

Chapter 5, p129, Q26(d). The answer on page 763 for the horizontal range should be in "m" not "m/s". Thank you to Tristan Ockwell, St. Laurences College, Brisbane.

Chapter 6, p140. In Figure 6.2, the last number on the x-axis should be 1015 not 10-15. Thank you to Michael Leask, Science Teacher at Caboolture State High School.

Chapter 6, p 137. Table 6.1 has wrong data in the Ca-H and Ha columns. The correct values are shown below. My thanks to Physics teaches Victor Braun (for pointing out the error) and Mark Shields (for giving me the correct values). Scratchies on their way chaps.

Chapter 6, p143. Physics fact: the spin of 1998KY26 takes 10.7 minutes not seconds. And the next line about the day being 0.09 seconds doesn't even make sense. Delete it! Thank you again to Michael Leask at Caboolture State High School.

Chapter 7, Q5, p172. The answer should be 9458 N not 9690 N as we have in the back of the book. We (I) used the density of freshwater (1000 kg m-3 instead of saltwater (1030 kg m-3). Thank you yet again to Michael Leask at Caboolture State High School. We owe you a moche latte.

Chapter 8, Q16. Correct answer is 16.3 m s-1. I'm not sure how we got that one wrong. A big thank you and two cans of Red Bull to the men with the keen eyes from St Laurences' College, Brisbane: Joshua Noronha and Duy Nguyen. Thanks again chaps!

Chapter 8, Q 14 (b), p197. The answer is 2.71 m/s not -1.86 m/s. The working is as follows:

As the jet is backwards (v=-35m/s) then (with bullet a, melon b and jet c)

ma.ua  = (ma + mb - mc).v + mc.vc

0.01x545      = (0.01+3-0.3)v+0.3x-35

5.45 + 10.5  = 2.71 m/s    (not -1.86!?). A big thank you to the Kennedy Assassination buff and Physics teacher Chris Smith (and his Yr 11 Physics class) at Sunshine Coast Grammar School.

Chapter 8, p206. In the solution to the example, the linear momentum should be 2.9 x 10-3 not 2.9 x 10-3. Also, for the rotational momentum the radius part should read (2.78 x 10-3)2 not (2.78 x 10-3)2. That's not my fault - that's the typesetter stuffing things up afterwards. But, I guess I should have checked. Thanks boys: that's Joshua Noronha & Ryan Schumacher from St Laurences' College, Brisbane again. This is getting embarrassing.

Chapter 10, Q40. Correct answer is 0.2 cm. See worked solutions. Credit to Anthony Reid, North Lakes State College. We owe you a half-strength decaf mocha latte.

Chapter 11, page 264 Table 11.1. The units for alpha should be °C-1 not m°C-1 Thank you to Vic Braun for spotting that.

Chapter 11, page 267 Table 11.2. The units for beta should be °C-1 not m°C-1 Thank you again to Vic Braun for spotting that.

Chapter 13, Q38. Correct answer is Open Pipe formula: L = nλ/4, where n = 1, 2, 3, 4, 5 (see webpage for diagram). Big thank you to the eagle eyed Joshua Noronha (St Laurances).

Chapter 15, page 337, Q15. The answer is the back (1.1 x 10-5m is wrong; it should be 8.281 x 10-6 m. The solution is thus:
For a soap film in air, the refractive indices go L-H-L so the formula is 2d = m λfilm
Where λfilm is the wavelength of the blue light in the film, which equals the wavelength in air/(refractive index of the soap film).
That is λfilm = λair/1.33 = 450/1.33 = 338 nm.
2d = m x 338 where m = the number of the band starting with the first band as m=0; thus for the 50th band m = 49.
2d = 49 x 338
d = 8281 nm or 8.281 x 10-6 m
The answer in the back was wrong as the wavelength of light in air (450nm) was used instead of the wavelength in the water medium (450/1.33).

Chapter 15, p326. Example, parts (c) and (d). The wavelength of 600nm found in part (b) has not been used in parts (C) and (D) - in fact 640nm has been used for some unknown reason (fat fingers?). The correct answer for (c) should be 2.25 x 10-2 m; and the correct answer for (d) should be x = 4.5 mm, thus thickness = 9.0 mm. As well, the formula in the box for (d) has some typos: the numerator on the LHS should read (1-½) x 600 x 10-9. My thanks again to Joshua Noronha (St Laurances). Goodness knows what he'll find in Chapter 16. I can hardly wait. My thanks to Rajika Subasinghe Arachchige (yet again) for correcting my corrections.

Chapter 16, page 364. Table 16.4 has a chainsaw listed with an absolute intensity of 100.5. This should read 10–0.5. My thanks to Benjamin Gray from Brisbane State High School for spotting this mistake. I'll fix it in the next edition for sure. Thanks, Ben. Appreciated.

Chapter 16, p376. The formula at the top of the page should have a vs in the denominator (on the bottom instead of vo. What a stupid mistake. My thanks to ACT Physics student Rajika Subasinghe Arachchige.

Chapter 18, p403. Question 8(c) should be 38° not 38°C (as it is an angle not a temperature). Heartfelt thanks to my eagle-eyed Year 11 student Claudia Bamford who wrote (in the form of a haiku it seems):

I have some excellent news!!
I found a mistake in the textbook.
Written by yourself.

Claudia also said: "I have attached a photo as evidence. Does this mean I get my name on your website???" Yes Claudia, a can of Golder Circle Creaming Soda will be yours soon. I'll make sure it is at 38°C.

Chapter 19, p 421. The text referring to Figure 19.8(c) under the subheading "Characteristics of the image" is wrong. Delete the words "between F and the lens" - this is clearly wrong. Thank you to Ron Grant for his eagle eye.

Chapter 19, p 423. Example calculation part (d): the image should be at -20 cm, not -10 cm. The error is in the last line. My thanks to one of Rowan Barber's physics students at Alexandra Hills TAFE, Redlands. Thanks guys.

Chapter 19 Q15, p426. It should say that the image was found on a screen.  Thanks Ron.

Chapter 19 Q27, p428. The answer in the back is wrong but the worked solution on the web page is correct. Thanks Ron.

Chapter 21 Q26 (d) page 464. The questions also asks for velocity in the direction of the field. The answer would be v = u + at = 0 + 1.67 x 108 x 8.3 x 10-6 = 1386 m/s, downwards. I also worked out the resultant velocity and that came to 1833 m/s at an angle of 49° below the horizontal. My thanks to Cobe LeClerc from Meridan State College for pointing out the omission.

Chapter 22, Q9, p479. In the table where it has 4 V the corresponding current should be 0.025A not 0.25A. Well spotted by Issy Burdon. Thanks Issy - I'd send a Scratch-it but times are tough.

Chapter 26 Q32. The slope of the line of the graph is 1.32 hence B =m/LN = 1.32/(0.1x100) = 0.132 N/A (NOT 1.3 as the book states). Sorry about the error. My thanks to teacher Chris Smith, Head of Learning Area - Science, Sunshine Coast Grammar School, Queensland.

Chapter 27. Questions 18 to 28 have the answers in the back (page 768) as Q19-29. Thank you to Kevin Fullbrook - Gold Coast Institute of TAFE  for pointing that out.

Chapter 28, page  624 - Predicting the type of decay. The two dot points are in conflict with the graph on page 625. The graph is correct. The dot points should read:

  • Beta decay will occur in those nuclides that are BELOW the line of stability.
  • Positron decay will occur in those nuclides that are ABOVE the line of stability. Thanks to Dylan Hudson, Year 12 Launceston College for pointing this out.

  • Chapter 27 p 615: Figure 27.22 is said to be for question 29, but is for question 28. Likewise Figures 27.21 and 27.20 are said to be for questions 25 and 28 respectively, but in fact relate to questions 24 and 27. Thanks to David Wiseman - Year 12 student at Toowoomba State High School - for spotting that.

    Chapter 28, page  625: the reaction at the bottom of the page should have as the product C-13 not C-12. David Wiseman yet again.

    Chapter 28, page  625. Q9a has a wrong answer in the back of the book. It should read Na-22 as in the question. The rest is okay. Thanks to David Wiseman from Toowoomba SHS for spotting that too.

    Chapter 28 p 629, first line under the N-13 decay equation. Should read "nitrogen" not "sodium". I think I had a brain freeze. Mr Pedantic - David Wiseman - from Toowoomba SHS again.

    Chapter 28 p 645: This is not really an error but to keep Mr Pedantic (David Wiseman) happy I will acknowledge that the sentence could be written more clearly. He said that his friend Steven Connell is disturbed with the statement six lines from the bottom that says 'Radiation that deposits one joule of energy per kilogram of tissue is called the absorbed dose.'   David said "However, radiation that deposits one joule per kilogram would have an absorbed dose of one gray. I think the sentence should read something like 'The absorbed dose is the radiation absorbed in joules per kilogram of tissue'". Thanks again David, I will make the change in the next edition. You should get a job with Oxford University Press as a proofreader (it would get you off my back).
     
    Chapter 29, p661. Jayke Anderson from Caboolture State High School pointed out that the equation used for solution part (c), v=fλ, is missing λ in the rearrangement. I would have sent a $2 Scratchie if it wasn't for the Global Financial Crisis.
