Hi Danny, I think the solution to Q7 should have 164ke^2, rather than 158 as the nucleus has changed. Thanks, Dave
E1 MCQs: Nuclear Structure (HL)Good point! I'll specify that the projectile is launched vertically.
A.1 practice: Projectilesquestion 1: the graph only shows height vs. time. The initial speed can't be figured by only looking at the vertical component of the motion.
A.1 practice: ProjectilesHey David, thanks so much for flagging this for us. The questions should be fixed now!
A.1 practice: ProjectilesHi InThinking team, Q8 - the answer is not an option?
A.1 practice: ProjectilesHi InThinking team, Q's 5 and 6 seem to be repeats on this page?
A.1 practice: ProjectilesThanks Zhenqi! I've done a general tidy up of units while here, too :)
A2 interactive: Circular motionQuestion #6 - it should be asking for centripetal force. The question now asks for centripetal acceleration instead.
A2 interactive: Circular motionAh yes, sorry, I see it now!
B5 MCQs: Current and resistance
