In the figure below, elevator cabs A and B are connected by a short cable and can be pulled upward or lowered by the cable above cab A. Cab A has mass 1680 kg; cab B has mass 1500 kg. A 30 kg box of catnip lies on the floor of cab A. The tension in the cable connecting the cabs is 1.90 ×104 N. What is the magnitude of the normal force on the box from the floor?

A new college friend you’ve met since the semester started has many allergies and intolerances to foods and other substances. They have asked you to share some of what you learn in the OTC class to help them manage their life better. Which of the following could you share with your new friend regarding what is not required to be listed in the inactive ingredients section on the drug facts label?
