Question

Lynn uses a spring scale to pull a block toward the right across the lab table. The scale reads eight N. Which force should Lynn conclude is also eight N?

a) Gravitational force
b) Frictional force
c) Tension force
d) Normal force

Answer 1

The force that Lynn should conclude is also eight N, as measured by the spring scale, is the frictional force, as it balances the tension force exerted by Lynn.

Step-by-step explanation:

Lynn uses a spring scale to pull a block to the right across a lab table and the scale reads eight N. The force Lynn should conclude is also eight N is the frictional force. This is because the spring scale measures the tension force, which is the force required to overcome friction and move the block at a constant velocity. In this scenario, if the block is moving at a constant velocity, then the net force is zero, indicating that the pulling force (tension) provided by the scale is equal to the frictional force resisting the motion.
