Answer:

The preoperational stage is the second stage in Piaget's theory of cognitive development. This stage begins around age two and lasts until approximately age seven. During this period, children are thinking at a symbolic level but are not yet using cognitive operations.

What is the advantage of applying learning approaches to the study of personality?

OlgaM077 [116]

The advantage of applying learning approaches to the study of personality is how individuals alter their behavior as a result of rewards, disciplines and other experiences in life, a method known as learning. Classic behaviorists center firmly on obvious behavior and therefore the ways in which it will be littered with rewards and punishments.

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

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