physics

How do relative velocities work near the speed of light. Say u r shooting a bullet that goes at 0.8c from a spaceship that goes at 0.8c, what is the velocity of the bullet relative to an observer on the ground? I know that this equation gives the answer, but could someone pls show how to derive...

Hi, I am a year 10 student, going into year 11 next year, and I have chosen to do Chemistry and Physics. I was wondering what textbook is the best to study for these subjects, so it would be great if I could get some guidance.

Hi I'm wondering if there were any specific phys and chem modules that are harder than others and need extra study or tutoring on (for preliminary modules but opinions on hsc modules as well)! I'm going to be attending tutoring for module 2 of chemistry (quantitative chemistry) but I'm not sure...

Hey, at the moment I'm a yr 10 student in 5.3 maths. I chose my subjects a while ago and I still have no clue what maths I should be taking with physics. I've been told by previous science teachers that I'm capable of doing physics and they recommend doing maths adv to everyone. I ended up...

Hi! I have been doing a few practice papers for physics and have a bunch of questions I am confused about! Does anyone know: 1. What is the best definition for an uncontrolled/controlled chain reaction. I would have said the number of fissions subsequently initiated in comparison to the number...

Hello, i just wanted to know what were the scientific theories and laws of physics that Ole romer based his measurement of the speed of light on. also what equipment did he utilise to make these measurements? any help asap would be greatly appreciated :)

hello, so my question is related to the measurement of the speed of light. 1. Maxwell predicted existence of em waves in 1864. He then went on to calculate the theoretical speed of an em wave. he then said that light is also an em wave. 2. then in 1900's hertz proved that em waves existed by...

I'm studying Physics and Chemistry, and I've tried the questions in the textbooks I use (surfing and in focus) but they all seem to be repetitive and are nothing like the harder questions in the HSC. Does anyone have any other textbook suggestions or resources with hard exam type questions for...

I'm in year 10 and am doing Ext. Maths, Adv. English, Economics, Physics, Chemistry, and engineering studies. I am looking for tutors for these subjects, preferably not personal. Any help would be great.

Hi! I am offering 1-to-1 (and possibly small group) tuition in: -HSC and Year 11 Mathematics (Advanced, Extension 1 and 2) and Physics. Math and Science subjects for younger years. -Other high-school level Math and Physics e.g. A-levels, IB, Olympiads. -University level Math and Physics...

How similar is engineering studies to physics? Would doing them both in years 11 and 12 be a good idea?

I'm going into Year 11 this year at a top selective school and I'm taking the Asian Five (Ext Maths, Adv English, Chemistry, Physics and Economics), plus Geography. My school only lets me choose up to 2 sciences. After speaking to some people who have graduated recently, I've heard that physics...

Hello guys, my name is Atef and I am a graduate with an ATAR of 96.45 and marks of 90 in both physics and 2u maths. I have been teaching for 6+years which means that I'm extremely comfortable with the new syllabus since I've seen all the topics at a higher level in University. What I offer: I...

Hi, I'm going to be going to year 11 next year and I'm getting kinda stressed about my science subjects. My subjects for next year are 3U Maths, advanced English, Chemistry, Biology, Physics and Geography. I am already doing English and Maths tutoring but I'm really scared of how I'm going to...

Hello! I am offering free tutoring for physics, chemistry, math advanced and ext 1 for year 9-11, via discord (preferably) or email. I am just started year 12 this term. I am currently doing physics, chemistry, math ext 2, economics. During my free periods and lunch time I usually help my...

Hello everyone, I know this may sound really stupid but I have a friend who goes to Matrix and she complained that her Physics teacher was not that good (I'm not sure about that because I think all teachers have to be qualified in order to teach, maybe?). I was wondering if there are any other...

If anyone has any of these physics for 2020 with solutions, please dm/pm me, I need to check if I got my answers correct! p.s ik its intellectual property, but if you could just dm/pm me the stuff through, greatly appreciated yoooooookkkkkkkkkkkkkkkkkkkkkkkk

I'm currently not sure what subjects to choose this year for my HSC. I'm certain that I want to take Economics, 3U Math, 3U English but I'm not sure whether to take Phys, Chem or Modern History. I did quite well in a recent Physics test, in comparison with other peers so I don't know if I should...
