Answer:
Explanation:
A free-body diagram is a sketch of an object of interest with all the surrounding objects stripped away and all of the forces acting on the body shown. The drawing of a free-body diagram is an important step in the solving of mechanics problems since it helps to visualize all the forces acting on a single object. The net external force acting on the object must be obtained in order to apply Newton's Second Law to the motion of the object.
A free-body diagram or isolated-body diagram is useful in problems involving equilibrium of forces.
Free-body diagrams are useful for setting up standard mechanics problems.
Answer:
Explanation:
A point charge of +2q centered in a conductive spherical shell of inner diameter a and outer diameter b will induce - 2q charge on the inner surface and +2q charge on the outer surface of the shell. Since 8q charge has been added to the shell , this charge will reside on the outer surface of the shell. so total charge on the outer surface will be 10q. At a point less than a , the electric field will be due to +2q charge situated at the centre . The electric field will be as follows
E = k .2q / r² for r < a
= 8kq/ a²
electric field at a point r = a>b
total charge lying inside is +2q - 2q = 0 . So in the thickness of the shell , electric field will be zero as total charge inside is nil.
For a point at r > b total charge inside is 2q-2q+10q = 10q , so electric field at r which is lying outside the shell .
E = k 10 q / r² for r > b

Explanation:
Physical development refers to the growth, physical and biological changes that happens in the humans body between birth and till they get to adolescence stage. There is development in brain, senses, they way they talk, physical appearance e.r.c.
Examples of these include, as humans grow, there is an increase in the way they interact with other people.
Babies tend to interact and learn new words even as their sense organs are been developed.
Cognitive development refers to how children develop in knowledge, skills, they way they think, their disposition and problem solving ability. These help children to think and understand their environment better.
Psychosocial development entails psychological and social development and it refers to how human personality is developed, acquiring social attitudes and skills from young age to adult. It entails how humans interact with their environment.
Moral development entails changes that occur in humans from childhood to adulthood by possesing the the skills and ability to know what is right and what is wrong i.e an understanding of morals behavior.
