The measurement error is defined as AX=X-Xo.where Xo is the true value of a physical quantity. X is the measured value of the physical quantity, AX is also known as "absolute error" What is the correct understanding to absolute error? Select one: O a An absolute error indicates the absolute value of the error. Ob Absolute error is the difference between the measured value and the true value. O e Absolute error indicates that the error is always positive. Od. Absolute eror indicates that the magnitude of an error is certain.

The skater pushes on the wall with their hand, this action sends the ice skater moving backwards across the rink at a slow pace. If the skater applied a force on the wall, why did the wall stay still and the skater move? (a) The skater applied too much force on the wall and moved the wall back. It only appears that the skater moved backwards. B The frictional force between the skater and the ice was greater than the applied force of the wall C The skater did not applied enough force on the wall and therefore could not stand still D The wall applied an equal and opposite force to the skater causing the skater to move backward on the ice (b) Use the scenario above If the skater had a mass of…
