Answer:
Explanation:Newton.s law of cooling states that the rate of cooling of an object is proportional to the difference between its own temperatures and temperature of its surroundings. Mathematically,
where is the heat transfer
is heat transfer coefficient
is the heat transfer surface area
is the temperature of the object's surface
is the temperature of the surroundings
Answer:
Explanation:
Density is a characteristic property bodies and materials, and is defined as the relationship between the mass and the volume , as shown below:
(1)
In the case of the neutron star, we know it has the same mass as the Sun:
And its radius is
On the other hand, if we assume this neutron star has a spherical shape, its volume can be calculated by the following formula:
(2)
(3)
(4)
Substituting (4) in (1):
(5)
Finally:
