Question

read the passage - new apartment - and answer the question below: 1e. the pair are able to move the couch across the smooth wood floor. however, when they got to the carpet, they had a more difficult time moving the couch. which statement best describes why this is true? a the force from the floor on the couch is higher on the carpet than on the wood floor. b. the coefficients of friction are higher for carpet than for wood floors. c. the coefficients of frictions are higher for wood floors than for carpet. d. the force of gravity changes as the surface changes.

Explanation:

Step1: Recall friction concept

Friction opposes motion. Higher - friction surfaces make it harder to move objects.

Step2: Compare surfaces

Carpet has a rougher texture than smooth wood floor, so it has a higher coefficient of friction.

Step3: Analyze options

A is wrong as it's about friction not just floor - on - couch force. C is incorrect as wood has lower friction. D is wrong as gravity doesn't change with surface type. B is correct as higher friction coefficients on carpet make moving the couch harder.

Answer:

B. The coefficients of friction are higher for carpet than for wood floors.
