Problem 5: Apparent Weight in an Elevator
- Apparent weight is greater than actual weight when the elevator is moving up and slowing down.
Problem 6: Static Friction - Assertion and Reason
- Assertion: Static friction is a self-adjusting force. (True)
- Reason: Static friction can vary from zero to a limiting value. (True)
- Relationship: Reason correctly explains the assertion.
