1. Someone puts a brick in a liquid. They use a Newton Meter to measure things. Upthrust makes the brick (and any other object)...

- Weigh less. Upthrust changes the weight.
- Balance with the forces around it.
- Appear to weigh less, but it doesn't really. It's weight stays the same.
- Create unbalanced forces, so the brick (and any other object) sinks.
