suppose that your pressure gauge for determining the blood pressure of a patient measured absolute pressure p instead of gauge pressure. how would you write the normal value of systolic blood pressure, 120 mmhg, in such a case?

iron would move it is magnetic there is a mag field around the current in the wire

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
