A lamp hangs vertically from a cord in a descending elevator. The elevator has a deceleration of 2.4 m/s2 before coming to a stop. (a) If the tension in the cord is 89 N, what is the mass of 27. Show by a qualitative argument that, because of the rotation of the Earth, a wind in the northern hemisphere blowing from north to south will be deflected to the right. What about a wind that is blowing from south to north? What is the situation in the southern hemisphere? the lamp? (b) What is the tension in the cord when the elevator ascends with an upward acceleration of 2.4 m/s
