Changing the revolving mass and keeping the radial force same the Period will alter. According to variations in revolving mass.

A force applied in a radial direction toward or away from the centre is referred to as a radial force. When a massed body or fluid element moves in a circular motion, an equilibrium between the centripetal force acting from the inside and the centrifugal force acting from the outside is created in the radial direction.

F = mv²/r

F = Force required to keep the mass in a circle

m = mass

v = velocity of the mass

r = radius of the circle.

Since, v = 2πr/t

Where t = period

π = pie

Substitute the value of v

We have, F = m(2πr/t)²/r

F = 4π²r²m/t²r

F = 4π²rm/t²

If the path radius and radial force are kept constant then mass is directly proportional to period

m ∝ t

Which means if mass increases period will increase as well.

Simple harmonic motion is performed by an object attached to an ideal spring. You could double the force constant to double the total energy.

Simple harmonic motion is a type of periodic motion in mechanics and physics in which the restoring force on the moving object is directly proportional to the magnitude of the displacement and act in the direction of the object's equilibrium position.

The unit mass to the spring executes a simple harmonic motion in this exercise, and the maximum mechanical energy is

Em = ½ k A²

Where A represents the range of motion

We must increase the amplitude or the spring constant to double the energy.

To double the total energy, we must either increase the amplitude by a factor of 2 or increase the spring constant by a factor of 2.

The changes (magnitude and direction) of the linear momentum of the object .-229.8 Kgm/s

The conservation of momentum states that, within a few problem domains, the quantity of momentum remains regular; momentum is neither created nor destroyed, but best modified through the movement of forces as described by means of Newton's laws of motion.

Calculation:-

Mass of object m₁ = 5 kg

velocity v₁ = 30 cos40° m/s

velocity =  - 30 cos40°m/s

Change in linear momentum = mass (v final - v initial)

                                                  = 5 ( - 30 cos40° -  30 cos40° )

                                                  = 5 ( - 30 × 0.766 -  30 0.766 )

The sudden cessation of energy generation causes the core to collapse and the star's outer layers to collapse onto the core.

What is core collapse?

Core-collapse supernovae are spectacular explosions that occur at the end of a big star's thermonuclear evolution, giving rise to neutron stars and black holes. They are among the most intense occurrences in the universe, play an important role in the synthesis and distribution of chemical elements, drive the development of new stars, and are closely tied to an enigmatic subclass of gamma-ray bursts. As a result, astro-physicists are keen to learn which stars burst as supernovae, what physical mechanisms produce the explosion, and what observable effects result from these cataclysmic events.

When the explosion wave generated in the optically obscured stellar centre eventually reaches the surface layers of the star, the visual supernova outburst begins.

The fire ceases because iron does not work as a fuel. The sudden cessation of energy output leads the core to collapse and the star's outer layers to collapse onto the core. The infalling layers compress so quickly that they 'bounce' off the iron core at near-lightspeed.
