• both magnitude and direction change
• only the direction change
• neither change

Answer 1

Answer:

what is true about the angular momentum of a cylinder rolling down a slope without slipping ? the answer is its magnetude changes but the direction remains constant plz explain how? angular momentum is r x mv . clearly the direction remins same always when cylinder rolls down but the magnitude of velocity changes.
