Answer:
The correct option is A.
Explanation:
Following the equation of continuum, AV remains constant.
Case a
(3A)(V0) = AV1 + AV1 + AV1
3AV0 = 3AV1
V1 = V0
Case b
(A)(V0) = (A/3)V2 + (A/3)V2 + (A/3)V2 + (A/3)V2
AV0 = 4V2/3
V2 = 3/4V0
Case c
(A/2)(V0) = AV3 + AV3 + AV3
AV0/2 = 3AV3
V3 = V0/6
Case d
(3A)(V0) = 2AV4 + 2AV4
3AV0 = 4AV4
V4 = 3V0/4
Comparing all the flow speeds, V1 is the largest.
Thus, the correct option is A.

<h2>Answer: Because they rotate really fast.
</h2>
First, it is necessary to clarify what is a pulsar (pulsating star) and what is a neutron star:
<u>A pulsar</u> is a neutron star that emits very intense electromagnetic radiation at short and periodic intervals due to its intense magnetic field that induces this emission.
<u>A neutron star</u>, is the name given to the remains of a supernova. In itself it is the result of the gravitational collapse of a massive supergiant star after exhausting the fuel in its core.
Neutron stars have a small size for their very high density and they rotate at a huge speed.
<h2>So, the way to know that a pulsar is a neutron star is because of its <u>high rotating speed.
</u></h2>
Nevertheless, it is important to note that all pulsars are neutron stars, but not all neutron stars are pulsars.
The answer is A.
p=m/v
p= 240/60
p= 4 g/cm^3
