what has happened to the number of barred spirals, compared to the total number of spirals, over time as the universe has aged?

A wave in which the motion of the particle of the medium is parallel to the direction of the propagation of wave is known as a longitudinal wave.  This is the definition of longitudinal wave.

Longitudinal waves are that kind of wave in which the particle of the medium Travels parallel in the direction of the propagation of the wave.

The longitudinal waves are also known as rear fractional waves and compressional waves because the particle in this wave moves in such a way that sometime they come very close to each other and sometimes they are far from each other.

Some of the examples of longitudinal wave includes the ripple in water, vibration in guitar string etc.

What is gravity force?

Gravity is the force that practically all material objects in the universe experience. From subatomic particles to clusters of galaxies, gravity affects objects of all sizes. The movement of planets around the sun and the free fall of apples from trees are both caused by this force.

A force throughout a medium's length is called tension, and in this context the force is carried particularly by a flexible medium like a rope or cable. Tension is measured in Newton per meter in the SI system. The forces acting on the beam are

chemical dynamism, Chemical bonds within substances contain energy. Exothermic chemical reactions are those that release chemical energy during the process, frequently in the form of heat. Some of the heat energy that is used to drive reactions that need to be heated up for them to continue may be stored as chemical energy in newly created bonds.

What is intensity?

As well as being the same as the energy density times the wave speed, intensity is the amount of energy a wave transports over a surface of a given area in a unit of time. Watts per square meter is the most used unit of measurement. A wave's power and amplitude will determine its intensity.

Here wavelenght (w) = 550 * 10^-9 m

The mass moment of inertia is 11873.0833

Einstein interpreted Mach's revelation to indicate that since gravity was/is the only known long-range force that could produce such effects, inertia would emerge as a "inductive" gravitational effect of cosmic matter in any correctly constructed theory of gravity.

Inertia is greater for lighter objects than for heavier ones. An object's bulk or weight have no bearing on its inertia. Every object has inertia, but only when it is at rest. The inertia of lighter items is lower than that of heavier ones.

width b = 17.0

length d = 29.0

The mass moment of inertia is d* b* b*b / 12

= 29.0 * 17.0 * 17.0 * 17.0 / 12

Velocity is defined as a vector expression representing the change in position over time of an object or particle. ​Acceleration is the rate at which the speed and direction of a moving object vary over time.

In simple harmonic motion, the acceleration is zero at the object's maximum speed. Maximum mass displacement in SHM equates to maximum acceleration. The momentum calculator uses the equation p=mv, or momentum (p) equals mass (m) times velocity (v).
