Final answer:
The net force of a crate being pulled requires considering all applied forces. To calculate the net force, you need to consider all the forces acting on the crate, including gravity, tension, friction, and any other applied forces. Newton's second law of motion can be used to calculate the net force (Fnet = ma).
Step-by-step explanation:
The net force of a crate being pulled requires considering all applied forces. It is not solely determined by the gravitational force, tension force, or magnetic force alone. To calculate the net force, you need to consider all the forces acting on the crate, including gravity, tension, friction, and any other applied forces.
To calculate the net force of the crate being pulled, you can use Newton's second law of motion, which states that net force equals mass times acceleration (Fnet = ma). By summing up all the relevant forces acting on the crate, you can determine the net force and its effect on the crate's motion.
