Answer: The given statement is False.
Lev Vygotsky gave a socio-cultural theory of cognitive development. According to this theory, socialization or social interaction of individual with people who are more knowledgeable than them plays a significant role in their cognitive development.
He described scaffolding as the support given to child by more knowledgeable others ( like parents or teachers). This means that scaffolding allowed communication between the teacher and the learner.
Thus, the given statement is False.
I think the correct answer from the choices listed above is option D. A mirage is created when light is refracted through layers of hot air just above a surface, causing it to follow a curved path. <span>A </span>mirage<span> is an optical phenomenon that creates the illusion of water and results from the refraction of light through a non-uniform medium.</span>
Kinetic Energy = (1/2) (mass) (speed)²
KE = (1/2) (400 kg) (50 m/s)²
KE = (200 kg) (2500 m²/s²)
KE = 500,000 kg-m²/s²
<em>KE = 500,000 Joules</em>
KE = 1/2 Mega-Joule
Answer: Options not given.
The correct option is one quarter wavelengths.
Here are the options.
a. one wavelength
b. half a wavelength
c. one-quarter wavelength
d. it depends on the wavelength
e. it depends on which mirror is moved
It must be moved by one quarter wavelength
Explanation:
The standard way to use oMichelson apparatus is to first measure the wavelength of the incident light. One of the mirrors is moved nearer or farther away while observing the fringe pattern. one of the mirrors at the end of an arm must be moved by one quarter wavelength in order to shift the pattern by half a fringe,
