    What Are the Key Concepts and Applications of Magnetism?

    Whoa calm it down, seroiusly wat is your problem? I am asking the question becuase i do not understand the answers? and i thought the thing from yesterday was telling me that my questions didnt make sense and i had to reword them, like you can either help or not but don't run me down on what...

    What Are the Key Concepts and Applications of Magnetism?

    I just have some questions about this stuff... How can the nature of a material determine if it can be made into a magnet? Whats the field around a straight conducter look like? Whats the direction of the magnetic field of a soleniod? Whats the action of a relay? How are the...

    How Does Magnetism Influence the Functionality of Telephones?

    Ok can anyone tell me how the nature of a material determine if it can be made into a magnet? Can anyone illistrate any ne of these to me - the field around a straight conductor - the magnetic field direction of a soleniod -the action of a relay how was the telephone developed...

    Intro to moving charges in a particle

    ohh i have another question... how is direct current different from alternating curent? Why do you thinkk the alternating current system was chosen in Canada?

    Intro to moving charges in a particle

    Can anyone describe to me what happens to electrons when one material is charged negatively by rybbing it on a second material, what must be different about the materials for this to work? And why does vinigear act as such a better electrolyte then water in a wet cell type? Why is a...

    How is Thermal Energy Converted in a Ballistic Pendulum?

    ohhh right i was doing 80 centimatres was 0.08 metres hahahaha whooops simple math too ok how about b and c?? anyone can help me out?

    How is Thermal Energy Converted in a Ballistic Pendulum?

    ohh ok so the mass for the initial is just 0.015 kg ok soo there is not hieght so that's adding no potential energy so i got 0.015(840)^2/2 ok so that's 5300J while my Em will be 18.80J so that's thermal energy of like 5288 j?

    How is Thermal Energy Converted in a Ballistic Pendulum?

    ok i get around 8500J for my begginign energy and about 20J for my ending energy does that make sense that 8480J would be thermal energy?

    How is Thermal Energy Converted in a Ballistic Pendulum?

    ohhh right my speeed would be zero because at the max hieght there is no speed

    How is Thermal Energy Converted in a Ballistic Pendulum?

    also wat is my speed in the Em as the bag rises? would i use 840 again as i did when the bag was stationary?
