A matchbox (5cm * 3.8cm * 1.3cm) with the material of a neutron star would weigh about ten billion tons on Earth. Estimate the density of such a star
To determine the density, we will use the formula ρ = / It is necessary to find out the volume of the matchbox V = 5 · 3.8 · 1.3 = 24.7 (cm3) translate the volume into m3: 24.7 cm3 = 24.7 · 10-9m3 Determine the density ρ = 1010 ^ 9kg / 24.710-9m 3 = 0.410 ^ 18 kg / m3
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
