your method for part b) seems a bit off

Well... maybe you shouldn't be hanging around large electrical tranmission towers. Its probably due to electric field created outside a wire. Similar to how if a large voltage is passed through a small rubber insulated wire you can still be shocked. The voltage in these sorts of towers is...

Hi I have a good understanding of the refraction of light and the reason it occurs etc. but what is confusing me is the exact reason for the "slowing" and hence bending of light inside a transparent material. What are the exact properties that allow a transparent material to slow a beam...

11.0 m/s^2 is incorrect when considering dilation of gravity. This error is most liekly due to human error in the recording of results e.g. time, distance, height. To improve experimental data experiments should always be repeated at least 3 times.

Does anybody know where I would be able to view a video of a wilson cloud chamber being used? I need to view one for homework. cheers

I'm not sure of the exact answer here but there are a couple of things i can think of. The reactive nature of potassium is dangerous but its more likely somethign to do with the aluminium reacting with the chlorate giving Aluminium oxide because aluminium in passivating and releasing chlorine...

Yeah I get that it only applies for solids. But I thought that in a photon-electron interaction either all the photons momentum or none of the photons momentum is given to the electron in the metal. From the above principle I applied the conservation of momentum and einstein's photoelectric...

So the thresold frequency is dependent on the properties of the valency band, right? Because i was fiddling around with waves and the idea that in the Photoelectric effect that either none or all of the momentum of the photon is transferred to the electron and i came up with a relationship...

In the Photoelectric effect what is the threshold frequency dependent on? This isn't homework I was just pondering. Is it the binding forces between the electron and the nuclues or is it dependent of a property of the photon?

Do you mean heavy metal in the ocean or being released in hydrothermal vents?

Why is gravity so strong in the oceanic region just to the left of England?

I am applying at the Sydney University. I would like to make the advance Science course but if i don't i will do a regular Bachelor of Science.

Thanks for that advice. I will apply for Bachelor of Science major in physics and HOPEFULLY get into the course and be able to study at uni.

I think I know what your talking about. Is it a graph that looks sort of like a zig-zag? If so the velocity at the peak of the balls bounce changes direction therefore the sign infront of the velocity changes. There is no velocity (neglectible) between those two points. Similarly when the...

I am considering a career in science and am particularly interested in physics but I'm unsure whether it is a wise career choice. I reside in Australia and next year I face university and I have plenty of queries about career in science. In Australia a system is used where at the end of final...
