thx so much.

thx heaps

I have a physics practical task really soon, and we are going to have to draw a graph. Alright. A few questions. 1) Does your axis have to start at zero, or can you start it on whatever number you want? 2) How do you draw a line of best fit. 3) Where do you stop the line of best fit, do you...

Pm me too.

That is weird indeed.. I don't know. In a case like this: the wire is always perpendicular to the magnetic field, so theta = 90 degrees.....and sin90 = 1. So in this case F = BIL is all you would need. However, in your case, I would think that you would need to times by sin(30).. Sorry...

What did josh say?

An AC induction motor relies on the principle that a moving magnetic field induces a current in the rotor with a direction that, according to Lenz’s law, causes the rotor to spin in the same direction as the magnetic field. THere is the motor effect and Faraday's law.......

re: HSC Physics Marathon Archive Is the average distance given the same as 'r' in Kepler's law of equation?

re: HSC Physics Marathon Archive OR... the muon one. (muons are tiny particles that are 'created' when cosmic rays hit our upper atmosphere.) They then travel towards the ground at close to speed of light. Muons are unstable and have a short lifetime (2.2x10 to the -6) when stationary. If we...

re: HSC Physics Marathon Archive 2 precise clocks. One was kept on ground, one was put on a plane that flew around the world. The two clocks were initially synchronised, but were out of synch after experiment. This shows time passes different in different time frames.

re: HSC Physics Marathon Archive is the average distance in the question the same as 'r' in Kepler's Law equation

re: HSC Physics Marathon Archive The planet Neptune orbits the sun at an average distance of 4.5 x 1012 m with a period of 5.2 x 109 s. The sun has a mass of 2.0 x 1030 kg. Show that Neptune’s orbit obeys Kepler’s Law of Periods.

re: HSC Physics Marathon Archive Ah...thx. Just had a memory lapse which mass was m zero. and forgot mass of proton was on data sheet.

re: HSC Physics Marathon Archive How do i use mass dilation equation?

re: HSC Physics Marathon Archive A particle accelerator is capable of accelerating a proton to a speed of 0.99c. Calculate the mass of this proton as measured from the reference frame of the collider.

what do these mean: u, v, ux, vx, uy, vy i know: u = Initial velocity v = final velocity ux = Initial horizontal velocity vx = Final Horizontal velocity uy = Initial vertical velocity vy = Final vertical velocity But What does this even mean..... I have an exam on monday, so any help ASAP...
