Which statement accurately describes an unbalanced force?
Responses
A 2-N force presses down on the cement block at the same time as a 1.5-N force presses up on the cement block.
A 2-N force presses down on the cement block at the same time as a 1.5-N force presses up on the cement block.
Three rows of cement blocks form a foundation for a house, and the house rests on this foundation.
Three rows of cement blocks form a foundation for a house, and the house rests on this foundation.
The force of a house pressing down on its foundation of cement blocks is 3,000 N.
The force of a house pressing down on its foundation of cement blocks is 3,000 N.
Each cement block supports a 2-N force, but when the foundation is built in a staggered pattern, it can support 2,000 N.
