Final answer:
When five people compete as one team in a tug-of-war contest, their combined effort level is likely to be stronger than if each individual competes alone.
Step-by-step explanation:
When five people compete as one team in a tug-of-war contest, their combined effort level is likely to be stronger than if each individual competes alone. The force exerted by each person adds up, resulting in a greater overall force applied to the rope. For example, if each person exerts a force of 100 N, the total force exerted by the team would be 500 N. In physics, forces can be added together to determine the total force in a system. So, with more people on a team, the combined force will be greater.
