    B Newton’s second law as one complete law

    There are only 3 components if the force/acceleration vector ISN'T along the same line as the reference axis. Why would anyone do that unless there are other forces/vectors/axes involved ?

    What was the first computer used for IC testing in the 1970s?

    It was the controller for a GenRad (1795?) functional tester. We also used DataGeneral Nova and PDP11/23 computers for system test.

    B Exploring the Concept of Energy Shape: Is Energy Limited by Matter?

    Is there any such thing as pure energy, or could Matter BE energy of a particular form ?

    I Calculating Force Needed to Pull Bungee Taught

    If it is held at anything other than vertical, it will get closer and closer to a straight line, but never achieve it.

    I Do you have an example of a truly random phenomenon?

    Crumpling a sheet of paper. It is HUGELY complicated/impossible to mathematically model.

    B When a bullet is fired from the back of train

    From your perspective, the bullet would follow it's normal parabolic (?) trajectory, just without air resistance.

    What to do with 1 year+ expired bleach?

    Use it as normal. It may not work as well as fresh stuff, but it probably will.

    Can a continous wave laser be converted to a more powerful pulsed laser?

    In my limited experience, pulse power can be a lot higher, but average power considerably lower.

    Securing Power from a 120VAC Generator: H3 and H8 Taps

    There are readily available 240 -> 120V transformers available for using power tools on building sites. They are generally "autotransformers" in that the secondary is simply half way through the primary i.e. centre tap, no isolation. You CAN use any twin-primary transformer by just connecting...

    I said "they don't act like SIMPLE resistors. They ALL have a temperature constant, they ALL have inductance and capacitance
