Answer:
Work done by battery will be equal to 10.238 J
Explanation:
We have given ideal an ideal battery with ideal voltage V = 24 volt
Constant current
Resistance will be equal to
Time is given t = 3 minutes = 3×60 = 180 sec
We have to find work done by battery
Work done is equal to
So work done by battery will be equal to 10.238 J

Answer:
The angular acceleration of the centrifuge is -231.74 rad/s².
Explanation:
Given that,
Angular speed = 3500 rev/min = 366 rad/s
We need to calculate the angular displacement
Using formula of angular displacement
Put the value into the formula
We need to calculate the angular acceleration
Using equation of motion
Hence, The angular acceleration of the centrifuge is -231.74 rad/s².
Answer:
Vygotsky's sociocultural theory asserts that learning is an essentially social process in which the support of parents, caregivers, peers and the wider society and culture plays a crucial role in the development of higher psychological functions.
