What prevents a pulsar from gravitational contractions?

EVERY star - every object in the universe, actually - is in a balance between its internal pressure trying to cause it to expand, and the mutual attraction of its own gravity. Planets of every size, and stars of every size, they all exist in this balance.

A pulsar got this way because the original star exploded and CRUSHED the core of the star into "collapsed matter", where all the protons, neutrons and electrons are merged together, without the massive space that normally separates these particles. Only the enormous gravity of the star could keep it collapsed that way, and it can't collapse any further because of nuclear pressure.

If a lot more mass were added - for example, if two pulsars were to collide and merge - then the added gravity MIGHT cause them to continue to collapse - into a black hole.

Some people ask "How much would a cubic centimeter of neutron star material weigh on Earth?", but the question is meaningless; you cannot take the collapsed matter away from the gravity source that keeps it collapsed, and if you could, it would re-expand into normal matter. Probably explosively.

Which is an example of gravitational potential energy i s a task?

An example of gravitational potential energy is the X-ray energy given off by X-ray pulsars. In this type of pulsar, gas and other matter in the accretion disk around the neutron star is ionized and falls along the magnetic field lines towards the poles of the pulsar. The gravitational potential energy is so high that the spots where the in-falling matter impacts the neutron star are hot enough to emit strong X-ray radiation.


Which is better pulsar 135 or pulsar 150?

First of all, the main distinguishing factor between Pulsar 150 and Pulsar 135 is the cost. Pulsar 150, as the name says, 150cc has more power, pick up and speed when compared to Pulsar 135. But, pulsar 135 has also got the equivalent features of Pulsar 150. (Because of the latest technology) In a nutshell, Pulsar 135 is a lite version of Pulsar 150. And, my opinion, Pulsar 150 is better...

A neutron star that rotates rapidly and emits light?

It's called a pulsar. However - ALL young neutron stars emit the said beam. It's only if that beam is detectable on Earth is it called a pulsar. So a Neutron Star and a Pulsar are the same thing. See related questions. but then again they are different.
