Starting from newton's second law, explain how a collision that is free from external forces conserves momentum. in other words, explain how the momentum of the system remains constant with time. newton's second law states that the acceleration of each object, which is proportional to each object's change in momentum, is proportional to the sum of the forces on the object. in the absence of external forces,

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e

Use the profile illustrated for problem (1). assume that the layer of silty sand fill (sm) is placed over the entire site. estimate the thickness of the fill (h - in feet) that will cause the effective vertical stress at the center of the clay layer to increase by 517.5 pounds per square foot.
