So if the difference between 1st and 2nd rank is 1% and for 2nd and 3rd it's quite large (15-20%), how would the top external HSC mark be distributed to end place? Would 2nd rank get an extremely similar mark to the highest external?
Cheers
What atar and umat percentile would you need to have a good chance at getting an interview for Med if from a rural area (if that even makes a difference).
Thanks
Our year had a Physics assignment given to us about 5 weeks ago (due 3 weeks time today). Due to half yearlies coming up in the next few weeks, I wanted to get it out of the way so I finished it off last week. However, in today's lesson we were told that they had changed the assignment to an in...
Does anyone have any ideas for an experiment that could be used to change one of the variables of the formula F=BILSin(theta) to measure the force. I was thinking of incorporating in a spring balance but am unsure how to set this up.
When Australia borrow money from foreign nations to counter the large debts we have in our current account, which account do these borrowings go into?

A projectile fired at a speed of u and an angle of x to the horizontal, reaches a
maximum height of H. When the same projectile is fired again at the same
angle with a new higher initial speed it reaches a new maximum height of 2H.
What is the new initial velocity in terms of u.
Find the net force acting on the Moon from the Earth and the Sun assuming that they are
at right angles to each other.
Mass of moon = 7.35 x 10^22 kg
Mass of sun = 1.99 x 10^30 kg
Radius of moon-earth = 3.84x10^5 km
radius of moon-sun = 1.5x10^8 km
Answer is 4.77x10^20 N at 24.6 degrees
I am able to solve the questions involving ratios, such as;
Two moons have masses M and 4m and radii R and 4R respectively. Compare their acceleration due to gravity.
How best should I set out my working for these?
Thanks
A rocket of mass 2000 tonnes, produces a constant thrust of 8x10^7N during liftoff by expelling 1500kg of exhaust gas per second.
Calculate the net force acting on an 85kg astronaut 30s after liftoff.
