Get an atom

Have you finished it yet? Were upto the torque bit and were supposed to have it finished in 3 weeks. Impossible, but my teacher has assured us that we will get it done and he is a senior marker for Physics and lectures at University level so i would assume he knows what he is talking about.

I have no idea how i missed that part of the question. Thanks so much for your help.

I take your word for it.

0.04 was one of the answers i got but i am so confused.

Thats the answer that i got, But the text book has it at 0.98N up

At the instant shown the plane of the coil is parallel to the direction of the magnetic field. The magnetic field strength is 0.45 T. When the current to the coil is activated it has a magnitude of 1.75 A in the direction ADCB. (a) Calculate the magnitude and direction of the force acting on...

When you put 99 into the atar calculator you get a atar equivalent of 99.3 but when you look it up on the UAC website it saids that maximum mark is 91. My teacher said that many people got band 6 in general maths but that means that most would have had to get 99/100 to get it. Which to me...

240000 = 1000 x 300 + 1/2 x a x (300)^2 240000 = 300000 + 45000a = - 6000 = 45000a a = -6000/45000 a = -0.133m/s/s towards the star ... You're of by a factor of 10. Simple calculation error. My teacher said that would have been a 4 mark question and you would have gotten 3/4

well we only started this top today so it cant be to complicated I am sure the answer that you got if correct. I will definetly keep you informed once i find out the awswer Thanks once again.

That god someone smart thinks its hard now i dont feel as bad for not knowing it. I am totally incompetent. Haha. The teacher i had today (sub) had no idea what she was talking about. Once again, Thanks so much P.s For the question below wouldnt you just use that formula a=u-v/t? as youre...

Heyy. Considering you have taken this topic, Can you help me with one more question? If yes then the question is below, If no then thats all sweet aswell. A rocket moving towards Alpha Centuari at 1000ms^-1 fires its rockets, accelerating backwards at a constant rate for 5 minutes. During this...

I see where i tripped up. Thanks so much..

And is the displacement after 2 seconds 51.6m?

A ball is thrown vertically upwards at 16ms^-1. What is the velocity after 2 seconds (acceleration is 9.8 m/s/s) Can someone please show working. Thanks in advance

Do you accelerate? You dont do your HSC until 2012.

PbO + CO ---> Pb + CO2 I dont quite know how to do this. Can someone give me a hand. Thanks. p.s Show how you did it. Thanks in advance.

According to 'Sam', you need to get 86 in all of them and you will get 91.55. But there are many factors that contribute to that score such as Internal Ranks
