Hey, to the fuckhead above. I'm new to this HSC system with all this align, moderate and uai calulation crap so try being helpful instead of a sarcastic fuck.

Hey, do you guys reckon I could get 85+? Maths 2U - Rank: 9/88 Band 6 English Std - Rank: 2/35 B6 Physics - Rank 5/41 B6 Economics - Rank 4/36 B6 Modern His - Rank 3/25 B6 Also, could my friend get 80+ (same subs as me)? Maths 2U - Rank: 44/88 B3 English Std - Rank: 3/35 B6 Physics - Rank...

Yep, thats what I thought. Appreciate your help guys =)

Hey, thanks for the reply. If voltage rises and resistance is the same, does that mean the current will rise? since each charge gains more potential energy.

Hey, I've recently been having trouble with connecting the dots between power, current, voltage, coulombs and energy. Been going through the textbooks but I need a deeper look into these units. So far I understand that an Amp is the measure of coulombs and that voltage is the force that...

Depends on the kind of plane, if your talking about a Cessna, then no problem. I assume that a VERY strong magnet will cause some disruptions on an airliner but it should still beable to land. I doubt the Fly by Wire systems will be affected as the wires and such are shielded against such...

OOH I see now. Thanks alot for your answers and suggestions.

The answers say that in d and e, the spaceship will contract.

Hey, can you guys help with this question. A spaceship is moving from Uranus (left) to Neptune (right) at high speed. Draw simple sketches describing how the following are visibly distorted:- a)Neptune relative to the spaceship. b)Uranus relative to the spaceship. c)Neptune relative to Uranus...

I think you read the question wrong. It says to move the object 80000k from the centre of the planet, so its not 20000km to 80000km, its 0km to 80000km.

Another one if anyone is there.. from `06 HSC, question 18 An object is stationary in space and located at a distance 10 000 km from the centre of a certain planet. It is found that 1.0 MJ of work needs to be done to move the object to a stationary point 20 000 km from the centre of the planet...

Yep, got it right. Thanks for the input guys.:sun:

Could someone help with this question from the 2006 HSC, question 16. (I reworded this as it needed a diagram to explain the question) A projectile leaves the ground at a horizontal velocity of 45m/s and a vertical velocity of 40m/s. a)State the horizontal component of the projectile’s...

Oh right, those were absolute values. I thought they were just brackets haha.

For D, how come its |GPE1-GPE2| instead of |GPE2-GPE1|??

Could someone please help with this 2007 Physics HSC multiple choice question. 3. The gravitational potential energy of a given mass is known at both Earth’s surface and at a fixed distance above Earth. What CANNOT be determined by comparing these two values of gravitational potential energy...

So if this is a 3U maths question, do you think it would be HSC Physics material? ie, used in the HSC's? :P

ah, thats what I was thinking, just needed someone to back me up :D

How does a force gauge work? I know Force equals mass times acceleration. When I try to exert a steady force on the gauge (no acceleration), it still gives me a reading of however many kgs of force I exerted. How is this?

Awesome, I got it right :D Thanks for your input guys.
