Question

question 7 of 25 a dump truck contains a load of soil. which action will leave the dump trucks inertia unchanged? a. add more soil. b. increase the force applied by the engine. c. dump out some of the soil. d. add gas to its fuel tank.

Explanation:

Inertia is related to mass. Adding or removing soil changes the mass and thus inertia. Adding gas to the fuel - tank changes the mass of the truck - fuel system. Increasing the engine force does not change the mass of the truck - soil system directly and does not affect inertia.

Answer:

B. Increase the force applied by the engine.
