Question

Which of the following is NOT correct concerning the properties of pulsars:

a. Were first thought to be evidence of extra-terrestrial life (LGM-1)

b. Rapid rotation due to conservation of angular momentum

c. Remnant of a supernova explosion

d. Very dense young star about the size of a terrestrial planet

e. Source of intense beams of energy

Answer 1

The properties of pulsars include rapid rotation due to conservation of angular momentum, being remnants of a supernova explosion, and sources of intense beams of energy. However, they are not very dense young stars about the size of a terrestrial planet.

Step-by-step explanation:

The correct answer is d. Very dense young star about the size of a terrestrial planet.

Pulsars are rapidly spinning neutron stars that emit beams of radiation. They are remnants of a supernova explosion and are incredibly dense, but they are not about the size of a terrestrial planet. Their rapid rotation is a result of the conservation of angular momentum.
