(d) Suppose two students are memorizing a list according to the same model dL dt = 0.5(1 − L) where L represents the fraction of
the list that is memorized at any time t. According to the uniqueness theorem, will the student who starts out knowing none of the list ever catch up to the student who knows one-third of the list? Explain.

Answer:
The minimum value of wall thickness t=3.63 mm.
Explanation:
Given:
D=200 mm
P=4 MPa
t= Wall thickness
maximum shear stress=27.5 MPa
We know that
hoop stress
Longitudinal stress
So maximum shear tress in plane
Now by putting the value
So t=3.36 mm
The minimum value of wall thickness t=3.63 mm.
Answer:
(b) 7.2 mJ
Explanation:
ENERGY STORED IN CAPACITOR: the energy is stored in capacitor in electric field
which can be calculated by expressions
E= c
=
=7200× J
= 7.2× J
=7.2 mJ
