Respuesta :

Answer:

Explanation:

The force of the lake bottom on the boat = force the boat exerts on the bottom

force the boat exerts on the bottom  = weight of the boat - buoyant force on the boat

so  

The force of the lake bottom on the boat  = weight of the boat - buoyant force on the boat

So

The force of the lake bottom on the boat will be less than its weight .
