It is still F=ma, or F=Impulse/time (which reduces to F=ma anyway), key thing is that the time taken for the object to come to rest has increased, so if a =(v-u)/t and t increases, then a decreases and consequently, F also decreases.

Re: YR12 Physics + Chem Tuition - HSC 2018/19 -Parramatta - HSC Marker- 10 Years Teac I now have over 30 students on my waiting list for HSC classes commencing in October, if you would like to be added to the list, please send me a PM or an email :)

Amen. I’ve had plenty of students with natural talent not get Band 6 and plenty of students who do not have that natural talent but have a much stronger work ethic that did get Band 6. I can’t remember the exact quote, but it was basically in every room at one of my old school: “Hard...

I used to like it 15-20 years ago! Well, Korean hip-hop. Jinusean FTW! I used to know all the “words” to Gasoline, lol. No idea what I was saying though

Never too old imo. When I did my B.Sc (Nanotechnology) there was a guy who must have been early-mid 30's doing the same course full time. Also the odd subject that I did with people who were 35+, including one subject I did with 2 people who each already had a PhD and must have been in their...

Uniball jetstream FTW

Dude can count like a mofo. One, two, red, blue. That shits crayyyyyyy

Awwwwww, such nice things said :redface: :smile: At the moment, all of my classes are actually completely filled and I have a waiting list of ~10 students, so you probably won't be coming to me for preliminary, lol. But, if you are keen to give me a try for HSC -- send me an email with...

Based on the comments of students who have come to me from these other institutions, I would feel comfortable recommending Matrix as long as you get one of the good teachers. I can’t recommend either of the others. Btw Drongoski > Du (3x the syllables = 3x the teacher!)

There is no steadfast rule on tolerances in HSC Marking. In a question such at this, it is all about process. So, if you show the correct processes, you would get the marks. Your answer would be fine as long as you showed how you got there. The answer may even be 2.3cm, I’m relying on my memory...

Rly? :haha:

Would you mind screenshotting what message comes up and sending to me? I don’t see any issues on the website side itself, but it would be useful for me to see what is coming up, just in case I have missed something. If you want to know anything about Sigma, send me a PM and I will answer all...

I do remember an answer of 2.2cm. If this is not what you get, post your working and we will see where you went wrong.

Jacaranda, Physics in Focus or Pearson. All seem decent -- Do different things well.

Re: YR12 Physics + Chem Tuition - HSC 2018/19 -Parramatta - HSC Marker- 10 Years Teac All preliminary classes are now completely filled and a waiting list has been started. If you are keen to lock in a position for the HSC 2018 course starting October, hit me up!

Seeing as the plane of the coil is perpendicular to the magnetic field, there will be no torque. T = nBIACos(@), in this case @ = 90 therefore T = 0. The forces on the sides of the coil will not force rotation of the coil (force on the top side is up and bottom side is down), rather they...

Re: YR12 Physics + Chem Tuition - HSC 2018/19 -Parramatta - HSC Marker- 10 Years Teac It doesn't look likely. All of my time is being taken with making awesome resources for the new Physics course! So, Chemistry is going to have to mg.

This is the very last concept in the Motors and Generators topic. No school is up to it at this stage (Unless you do M&G first) and it is a application of Faraday/Lenz Laws in an AC induction motor. If you acquire a solid understanding of Faraday/Lenz when you do it in school — this will...

What a champion! Love this dude.

Just salty you didn’t get on it back in January :tongue: Along with selling hotdogs to an overweight American father at every event he attended, Rayquaza put my kids through college.
