Answer: The magnetic flux is 3.4 × 10^-3 Wb
Explanation: Please see the attachments below
To determine the displacement, since we are given the potential energy, we use the equation for potential energy. For a spring, it is one-half the product of the spring constant and the square of the displacement. We do as follows:
PE = kx^2/2
5 Nm = 50N/m (x^2)
x = 0.32 m
Therefore, the displacement would be 0.32 m.
The Earth's spin in its axis each 24 hours
Answer:
I (cylinder) = 1/2 M R^2
I (sphere) = 2/5 M R^2
The equation of motion shows
I * alpha = M g R sin theta = const
An increase in the moment of inertia will result in a smaller acceleration
The cylinder will have the smallest forward velocity because it will arrive at the bottom after the sphere
