An ogre has a mass of 1000 kg and tries to walk across an 8 m drawbridge (from the castle side). the chain supporting the bridge is attached to the wall 12 m above the bridge and to the bridge at the point 5 m from the castle.
the ogre stands 1 m from the end of the bridge, and the bridge itself is 20 degrees below the horizontal.
if the bridge itself is 2000 kg, what is the tension in the chain?
since acceleration is constant
so the distance moved in constant acceleration will be given as
as we know that
t = 17 s
so distance moved is given by
so distance moved will be 170 m
well a basic explanation is that some elements have enough electrons to be considered stable. these elements do not need to react with other elements to gain more electrons. reactive elements are no where near stable; they respond with other elements in order to become stable. the more unstable, the harsher the reaction is.
'd' is the scalar. it has size but no direction. the other choices have directions too, so those are vectors.
