According to Jean Piaget, unrealistic idealism often occurs in adolescence as a result of egocentrism. Egocentrism is defined as the inability to understand or comprehend any point of view other than their own. Piaget claimed that adolescents are egocentric and are only seeing the world only from their personal point of view.
Answer:
The correct option is energy levels
Explanation:
Rutherford's model of an atom suggests that an atom has a tiny positively charged central mass (now called the nucleus) which is surrounded by electrons (negatively charged) in a <em>cloud</em>-like manner.
Bohr's model went a bit further than the Rutherford's model in describing an atom by suggesting that the electrons which surrounds in the nucleus travel in <u>fixed circular orbits</u>. This description by <em>Bohr was able to describe the energy levels of orbitals which assumes that smallest orbitals have the lowest energy while the largest orbitals have the highest energy</em>.
Answer B is the correct answer
We know that kinetic energy , where m is the mass of object and v is the velocity of object.
In this case only velocity is the variable, mass remains constant.
So point having higher velocity has higher kinetic energy.
When it leaves the racket, the ball will be having a certain height, but just before it reaches the ground it will not having any height. So maximum velocity of ball is at that time when it reaches just above the ground.
So option B is the correct answer.
Answer:
Maximum magnetic field will be 0.288 T
Explanation:
We he given number of turns in solenoid N = 23800
Length of the solenoid l = 1 m
So number of turns per unit length in the solenoid
Maximum current in solenoid i = 100 A
Magnetic field due to solenoid is equal to
As the current is maximum so magnetic field will be also maximum
So maximum magnetic field will be 0.288 T
To determine the distance that you would travel by.
Simply convert 15 minutes to seconds which would be 900 seconds.
Then solve for distance, which would be
D = r • t
D = 12 m/s • 900 s
D =10 800 m.
This is the distance that you had ran for.
