A typical neutron star has a mass of about 1. 5msun and a radius of 10 kilometers
Triss [41]

How thick a layer would Earth form as it wraps around the neutron star’s surface is: 6.67 10⁻³ m.

<h3>Density of the Neutron star</h3>

Density

ρ = m / V

Where:

ρ= density

m = mass of the planet 5.98 10²⁴ km

V =volume of the spherical layer

Volume of a sphere

Volume = 4/3 π r³

Mass = 1.5 = 1.5 1,991 10³⁰

Mass= 2.99 10³⁰ kg

Density:

ρ = 2.99 10³⁰ / [4/3 π (10 10³)³]

ρ is = 7.13 10 17 kg / m³

V = 5.98 10²⁴ / 7.13 10¹⁷

V = 8,387 10⁶ m³

Thickness of the layer

V = 4π r² e

e = V / 4π r

e = 8,387 10⁶ / [4π (10 10³)²]

e = 6.67 10⁻³ m

Inconclusion how thick a layer would Earth form as it wraps around the neutron star’s surface is: 6.67 10⁻³ m.

Ray purchases a paperweight and wants to cover it in paper. He creates the picture below to show the net of the figure. Ray only
sergey [27]

The square inches of paper Ray needs are equal to the area of the sides he wants to cover.

<h3>What is the area?</h3>

The area of an object refers to the surface or space occupied by the object.

<h3>Why is the area important?</h3>

In this situation calculating the area is essential because by doing this, Ray can know how much paper he needs.

<h3>How to calculate the area?</h3>

Different formulas can be used to calculate the area depending on the shape of the object.

  • Rectangle: Side x side
  • Triangle: 1/2 base x height
  • Circle: πr2

This means to know the exact answer, Ray needs to calculate the area of the sides he wants to cover and this is equal to the paper he needs to buy.

Note: This question is incomplete because the picture was not attached. Due to this, I answered it based on general knowledge.
