The total moment of inertia about an axis is : for a ring of mass m and radius straight r attached to a thin rod.
<h3>
Determine the Total moment of Inertia about an axis </h3>
<u>Given data:</u>
mass of ring --> m
radius of ring --> r
mass of rod --> M
Length of rod ---> L ( 2 * radius )
Total Moment of Inertia about an axis = Irod + Iring
where : Irod = moment of inertia of rod, Iring = moment of inertia of ring
Irod = ML² / 3
Iring = 2mr² / 5
moment of inertia around an axis by Iring = I
where ; I = 2mr² / 5 + ML² according to parallel axis theorem
Hence the Total moment of Inertia about an axis is :
Itotal = 2mr²/5 + ML² + ML² / 3
=

Answer:
A
Explanation:
The figure shows the electric field produced by a spherical charge distribution - this is a radial field, whose strength decreases as the inverse of the square of the distance from the centre of the charge:
More precisely, the strength of the field at a distance r from the centre of the sphere is
where k is the Coulomb's constant and Q is the charge on the sphere.
From the equation, we see that the field strength decreases as we move away from the sphere: therefore, the strength is maximum for the point closest to the sphere, which is point A.
This can also be seen from the density of field lines: in fact, the closer the field lines, the stronger the field. Point A is the point where the lines have highest density, therefore it is also the point where the field is strongest.

Playing hockey, driving a car, and even simply taking a walk are all everyday examples of Newton's laws of motion.
Answer:
The answer is cooperation
Explanation:
Cooperation means too work together to the same end

The direction of the centripetal acceleration is towards Saturn
Explanation:
When an object moves in a circular motion, there must be a force that "pulls" the object towards the centre of the circle, keeping it in a circular motion. This force is called centripetal force.
As a consequence, due to the relationship between force and acceleration (Newton's second law), there is also an acceleration that points towards the centre: this acceleration is called centripetal acceleration.
The magnitude of the centripetal acceleration is given by:
where
m is the mass of the object
v is its speed
r is the radius of the circle
Therefore in this situation, the centripetal acceleration points towards the centre of the circle: therefore, towards Saturn, which occupies the centre of the circular trajectory.
