The temperatures of one northeastern state range from 105° F in the summer to -25°F in the winter. Express this temperature range in degrees Celsius and in kelvins. *

Farenheit is an interesting unit so the conversions get a bit weird.

To convert from Farenheit to Celcius you follow this formula:

T(°C) = (T(°F) - 32) × 5/9

It is also easier to convert to Celcius to Kelvin shown in this formula:

T(K) = T(°C) + 273.15

To Answer your question:

105° F = 40.5°C

-25° F = -31.7°C

105° F = 313.65K

-25° F = 241.45K

The minimum mass so that material on its surface remains in place during the rapid rotation is  .        

Explanation:

Given that,

Certain neutron stars are believed to be rotating at about 0.70 rev/s.

Radius of the star, r = 119 km

When the star rotates the gravitational force is balanced by the centripetal force as :

So, the minimum mass so that material on its surface remains in place during the rapid rotation is  .
