Which of the following situations is impossible? Andwhy?

Pleaseelabourate on each onein detail and explain for each example why it could orcouldn't be possible. Also, please draw simple diagrams(example ----> <----- or <----- -----> etc) for eachsituation. This will help in determining in 'impossible situations'exactly why exactly they are "impossible". Am looking for adetailed, concept-oriented response.

Before beginning, pleaseexplain what velocity and acceleration are plushow and why they aredifferent from one another. Also explain what zero velocity and constant, non zero velocity is.Furthermore, what is zeroacceleration and what is constant, non-zeroacceleration?

a) An object has velocity directed east and accelerationdirected east.

b) c) An object has velocity directed east and accelerationdirected west.

c) An object has a constant non-zero velocity and changingacceleration.

d) An object has a constant non-zero acceleration and changingvelocity.

e) An object has zero velocity but non-zero acceleration.

P.S If a object stops moving at a point. Then must itsacceleraion be zero at that point? Why? or why not?

Which of the statements regarding this situation are true? Selectall that apply.

1-When one charged sphere is placed inside another the net electricfield outside the larger sphere is always larger than the field dueto the larger sphere alone.

2-If there is a positive point charge present at the center, thefield in all regions is either zero or directed away from thecenter.

3-When one charged sphere is placed inside another the net electricfield outside the larger sphere is always non-zero.

4-It is possible to have no electric field inside the outer sphereand a non-zero electric field outside the outer sphere.

5-If the outer sphere is present the electric field between itsinner radius and its outer radius (inside its solid wall, in otherwords) is always zero.

6-It is not possible to have a non-zero electric field inside theinner sphere and outside the outer sphere, but no electric fieldbetween the inner and outer spheres.

7-For a conducting sphere with a net charge Q, the electric fieldinside the sphere is zero and the electric field outside the sphereis the same as the field from a point charge of charge Q placed atthe center of the sphere.

8-As you move steadily out from the origin in this simulation theelectric field changes smoothly. The field can never jump suddenlyfrom one value to another.

9-If the outer sphere is present the way charge is distributed onthe outer sphere depends only on its charge, and not on the chargeof the point charge and the inner sphere.

Q8.9 In a completely inelastic collision between two objects, where the objects stick together after the collision, is it possible for the final kinetic energy of the system to be zero? If so, give an example in which this would occur. If the final kinetic energy is zero, what must the initial momentum of the system be? Is the initial kinetic energy of the system zero? Explain.
