Answer:

a) Eo = -C/ro + D exp(-ro/p)

1) dEN/dr = C/r² - D exp(-r/p)

2) Eo + C/ro = -Dexp(-ro/p)

C/ro = -Dexp(-ro/p) - Eo

∴ C = -ro(Dexp(-ro/p) + Eo)

3) EN = -(-ro(Dexp(-ro/p) + Eo)/r + Dexp(-r/p)

EN = ro(Dexp(-ro/p) - roEo/r + Dexp(-r/p)

EN + roEo/r = ro(Dexp(-ro/p) + Dexp(-r/p)

roEo/r = D(exp(-ro/p) + exp(-r/p) - EN

∴ Eo= r{D(exp(-ro/p) + exp(-ro/p) - EN}/ro

Think of a bath sponge. What happens when you squeeze it? How could you explain it from the point of view of the state of the ag

harkovskaia [24]

Answer:

What happens when it is squeezed is that its volume increases, the pressure of the material increases.

Explanation:

This is due to the fact that the elastic modulus of the sponge is high and withstands broad forces without deforming its structure, since the force is made within the proportional limit of its particles without modifying or permanently deforming them, that is why when stopping doing pressure or force on it its shape returns to being the original, this also happens due to the phenomenon of resilience
