Final answer:
The student's apparent weight while traveling upwards is 73N.
Step-by-step explanation:
In this scenario, the student's apparent weight can be calculated using the equation:
Apparent Weight = (Actual Weight) - (Force exerted by the elevator)
Since the elevator is moving upwards at a constant velocity, the net force on the student is zero. Therefore, the force exerted by the elevator upwards is equal to the weight of the student. So, the student's apparent weight while traveling upwards is equal to 73N, which is option a in the given choices.
