no, they would
i'm a mechanic so i know all about this stuff.
none of the three examples you gave would do very good in a ice
motor oil gets extremely hot during operation and undergoes being thrown around, getting dirty,
syrups are sticky and thick. oil needs to be atleast a little runny to work in a car engine so that it does not clog parts like the camshaft or valves.
hope this !
a frame of reference can be thought of as the state of motion of the observer of some event. for example, if you're sitting on a lawn chair watching a train travel past you you could even watch a glass of water sitting on a table inside the train move this seems like a simple and obvious example, yet when you take a step
you can use a symmetry argument to determine the net electric field at the center of the square.
each one of the square's corners is equidistant from the center. you can then argue that the contribution to the field at the center from each charge is equal in magnitude.
you can also argue that, for any charge placed on the square, its contribution to the field can be matched with and canceled out by the contribution from the charge on the opposite corner (e.g. the contributions from the top-left and bottom-right charges will cancel out).therefore, the magnitude of the net electric field at the center of the square is 0 n/c
