Several motorboats with the same mass are used in an experiment. The forces of the different motors versus their accelerations are graphed. What is the y-intercept of this graph?
the velocity
the inverse of the mass
zero
the mass***
Ok! thanks
The y-intercept of the graph is the value of the dependent variable (acceleration) when the independent variable (force) is equal to zero. In this case, the mass of the motorboats is the same, so the force acting on each motorboat will be zero when the acceleration is zero. Therefore, the y-intercept of the graph represents the mass of the motorboats. So, the correct answer is "the mass".
To find the y-intercept of the graph that represents the relationship between the forces of the different motors and their accelerations, you need to understand the variables involved.
The y-intercept of a graph represents the value of the dependent variable (acceleration in this case) when the independent variable (force in this case) is zero. This means that when there is no force acting on the motorboats, what value does the acceleration have.
The y-intercept for this graph is zero. This is because when there is no force acting on the motorboats, they will not experience any acceleration - they will not start moving or change their velocity. This is consistent with Newton's First Law of Motion, which states that an object at rest or in motion with a constant velocity will remain in that state until acted upon by an external force.
Therefore, the correct answer is zero.
