Freud (1905) stated that events in our childhood have a great influence on our adult lives, shaping our personality. He thought that parenting is of primary importance to a child's development, and the family as the most important feature of nurture was a common theme throughout twentieth-century psychology (which was dominated by environmentalists theories).

We are given
m = 4 kg
L = 21 cm
D = 12 cm
Thin-walled cylinder
I think what is asked is the moment of inertia of the cylinder about its axis. The formula is
I = MR²
substituting the given values
I = 4 (12/2)²
I = 144 kg cm²
Answer:
Mass = 100 kg
Acceleration due to gravity = 9.8m/s
Height = 10 m
Work done = mgh
= 100 x 9.8 x 10
= 9800 J

Given:
I=8A
t=2second
Potential difference,V=120-100=20volt
Workdone=V×i×t
=20×8×2
=320 joule.
The correct answer is 19.72 °C. The first step is to determine the amount of heat that was lost per gram (30,000 J) / (390 g) = 76.92 J/g. Then to determine the temperature change, divide 76.92 J/g with the given specific heat of milk (76.92 J/g) / (3.9 J/g°C) = 19.72 °C.
