Explanation:
a) The system mass-spring is well described by the following equation of equilibrium:
After some handling in physical and mathematical definition, the following non-homogeneous second-order linear differential equation:
The solution of this equation is:
The velocity function is:
Initial conditions are:
Equations at are:
The spring constant is:
After some algebraic handling, amplitude and phase angle are found:
The position can be described by this function:
b) The period of the motion is:
The amplitude is:
The phase of the motion is:
Answer:
True.
Explanation:
The magnetic axis and rotation axis of both of these planets are misaligned that why it is right to say that the magnetic fields of both Uranus and Neptune are highly tilted relative to their rotation axes and significantly offset from the planet's centers.
