When babies are able to babble "ba ba ba" they are in the Canonical Babbling stage. In this stage, babies are learning to recognize and order the sounds in order to form words. This stage starts around 7-8 months of age and lasts until 10-15 months when the first words emerge.

Here the correct option is option A Government positions were based on skills and merit.

Explanation - Earlier in China recruitment in high offices was done on the basis of recommendations that were given by officials about those post but under Confucianism examination system this method was barred. The talented people had to pass an exam that was really tough to crack for which they had to first give an exam at local level to qualify. No relation or recommendations were further entertained.

Cognitive process in ope-rant conditioning

Explanation:

The cognitive process is the process related to the mental process in which a person involved in the process of gaining knowledge and comprehend the knowledge. In this process many processes are involved such as remembering, knowing, judging and problem-solving.

It encompasses the knowledge and it is higher-level processing in which imagination, language, planning, and perception are involved. Many of the psychologists think that people acquire knowledge through observation and perception.

In this process when a person sees any object, hear any voice will transform that information into signals and that person's brain can take that cue and can act upon that cue. Thus in above statement cognitive process play a role in ope-rant behavior

A basketball is dropped from the edge of a cliff at the same time that second basketball is thrown upward from the ground. When

pentagon [3]

Answer:

The collision occurs at a height of 1/3 of the total height of cliff.

Explanation:

The situation is represented in the attached figure:

For the stone dropped from top of cliff we have

Initial velocity of drop= 0 m/s.

Now the time at which it attains a velocity of 2v is obtained from first equation of kinematics as

$v_{f}=u_{i}+gt\\\\2v=0+gt\\\\\therefore t=\frac{2v}{g}$

Thus the distance it covers in this time can be calculated using third equation of kinematics as

$v_{f}^{2}=v_{i}^{2}+2gh\\\\(2v)^{2}=2gh_{1}\\\\\therefore h_{1}=\frac{2v^{2}}{g}$

For the stone thrown upwards the velocity at collision is give as 'v' thus the velocity at which it is thrown upwards can be calculated by first equation of kinematics as

$v=v_{i}-gt\\\\\therefore v_{i}=v+gt\\\\v_{i}=v+g\times \frac{2v}{g}\\\\\therefore v_{i}=3v$

The height over which it changes it's velocity from '3v' to 'v' can be again obtained from third equation of kinematics as

$v^{2}=(3v)^{2}-2gh_{2}\\\\v^{2}=9v^{2}-2gh_{2}\\\\\therefore h_{2}=\frac{4v^{2}}{g}$

$\therefore h_{2}=2h_{1}$

Thus the collision occurs at at a fraction of 1/3 of height.

Answer:

answer

Explanation:

How did England's experience differ from that of the German states? England did not suffer any wars on the mainland (other than small upraising) once Scotland was taken and became a part of the empire even before its rise to superpower under Elizabeth 1.
