Answer:
The maximum frequency of revolution is 3.6 Hz.
Explanation:
Given that,
Mass = 8 kg
Distance = 400 mm
Tension = 800 N
We need to calculate the velocity
Using centripetal force
Where, F= tension
m = mass
v= velocity
r = radius of circle
Put the value into the formula
We need to calculate the maximum frequency of revolution
Using formula of frequency
Put the value into the formula
Hence, The maximum frequency of revolution is 3.6 Hz.
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.
Answer:18.29m/s^2
Explanation:
Centripetal acceleration=(velocity)^2÷radius
Centripetal acceleration=(32^2)/56
Centripetal acceleration=(32×32)/56
Centripetal acceleration=1024/56
Centripetal acceleration=18.29m/s^2
If the award weighs 200 newtons and 200 newtons equals 44.96 pounds of force even though it is of such a force if it hits the ground the energy will either discharge into the air doing nothing but creating a loud sound or it will discharge into the ground altering the ground that it landed on.
Hope this helps :)
