b) the mass moment of inertia about z axis passing the rotation center O is:

c) The mass moment of inertia about z axis passing the rotation center O is:

Answer:
the force would increase 4 times more
Explanation
more force results more mass or acceleration
Answer:
Because the force is inversely proportional to the square of the distance
Explanation:
The magnitude of the electrostatic force between two charged particles is given by

where
k is the Coulomb's constant
q1, q2 are the magnitudes of the two charges
d is the distance between the two charges
We observe that the magnitude of the force is inversely proportional to the square of the distance.
Therefore, when the distance changes to

The force will double:

Through an earth-based telescope you can see Jupiter more clearly than Mars because Jupiter is much larger than Mars and through the telescope you see the larger objects more clearly.
Hay muchos ejemplos importantes de fuerzas que no funcionan porque actúan perpendiculares al movimiento. Para el movimiento circular, la fuerza centrípeta siempre actúa en ángulo recto con el movimiento. Cambia la dirección del movimiento, pero no funciona en el objeto.
