Answer:
v = 54.2 m / s
Explanation:
Let's use energy conservation for this problem.
Starting point Higher
Em₀ = U = m g h
Final point. Lower
= K = ½ m v²
Em₀ = Em_{f}
m g h = ½ m v²
v² = 2gh
v = √ 2gh
Let's calculate
v = √ (2 9.8 150)
v = 54.2 m / s
Dont mind the top part, hope this helped
<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.
Answer:
All the hairs on the child's head must gain the same type of charge. Like charges repel so the strands of hair experience a force that pushes them away from each other.
