Answer:D) Egocentrism
Explanation:
Mr.Tong should be alerted to Piaget's concept of Egocentrism which is under the pre operational stage of Piaget's theory.
Following are the key features of Pre operational stage
- Centration
- Egocentrism
- Play
- Symbolic Representation
- Pretend (or symbolic) Play
- Animism
- Artificialism
- Irreversibility
The feelings and actions of children are usually self-centered. Egocentrism refers to the failure of the child to see a situation from another person Perception.
The self-centered child believes that other people see, hear, and feel exactly the same as the child does, according to Piaget.
Here Also 5 year old daughter does not think about her father and ask question blatantly
The illumination of the book is found to be approximately equal to 15 lx.
Option 1.
Explanation:
Luminous flux is the measure of power of the light emitted from a source and illumination is the property of the light to illuminate a given surface when it falls on the surface. So the measure of the region the light flux illuminates the surface is termed as illumination.
As here the luminous flux is given as 1759 lm and the distance of the object which has to be illuminated is placed 3 m away from the source ,the illumination is found to be directly proportional to the luminous flux and inversely proportional to the square of the distance between them
So, the illumination of the book is found to be approximately equal to 15 lx.
Sometimes if you're a fast worker then more job can be done. if you're slow it will take a lot more time. So I guess depends on situation.
You are calculating the Entropy of the system.
Answer:
The core: this structure of the terrestrial world is made up of sulphur, iron, silicon and it is found at the centre of the terrestrial world.
The mantle: this structure of the terrestrial world is located between the outer core and the crust and consist of mainly silicate rock.
The crust: this is the structure of the terrestrial world that makes up the outermost layer. It consist of granite and basalt.
Differentiation: this is the process by which gravity separates materials according to density, with high-density materials sinking and low-density materials rising.
Lithosphere: this is made up of the hard and rigid outer layer of the terrestrial planet and it's located between the crust and the outermost mantel.
The five terrestrial worlds includes Mercury, Venus, Earth, the Moon, and Mars. The largest which includes the Venus and Earth has the thinnest lithosphere while the smallest ( mercury and moon) have the thickest lithosphere.
