yay thanks

hi, i have an exam on wave properties in a week. and i found this on the syllabus. i can't remember learning it let alone what a cathode ray oscilloscope is (an electron gun thingymajig?) my textbooks don't explain it well. so if you know how to determine the frequency of sound using a...

i would also like to know how they worked

iv tried them - they make you quite well enhanced (they increased by length by 1 inch, so by 20%! score!) but its rele rele painful! it like throbs loads. anyway let's get back to physics

sorry but i wasnt sure where to post it

:cry: i need help solving problems involving selecting things. like for example find the number of ways in which a team of 3 men and 2 women can be selected from a group of 6 men and 5 women. im doing a retake of a statistics exam i did v badly in btw. i can't find any good websites about...

hello i need help solving problems involving selecting things. like for example find the number of ways in which a team of 3 men and 2 women can be selected from a group of 6 men and 5 women. :bugeye: i know how to do perms and combs but just don't know how to apply them.:eek: help...

oh thanks! i remember hearing about the length but not having actually measured one before, i was lost! :-)

hello i really struggle with this! i can never get the equations right or anything! i can't find any sites that help! i have a practical exam tomorow that could be about it please help thanks

could someone please give me a few pointers? I've tried careers advisors but they just leave me feeling even more confused! i would like to do a combined science degree with more emphasis on physics. so far the only career that has struck me as something id love to do is a school science...

hi, i don't know what career to pursue. i was thinking along the lines of physics and science. i'm new to the forum and am interested in shaft lengths, and replied to the shaft post, but nobody replied. i'm thinking of being a science technician as i like the school atmosphere and being...

what is the average shaft length? I am doing an experimental plan. is it around 7 inches? help much appreciated
