Answer:
3°F, 0°F, -11°F, -16°F, -20°F
Explanation:
The Fahrenheit scale is a temperature scale proposed in 1724 by the physicist Daniel Fahrenheit.
In this scale:
- The freezing point of water is set at 32 degrees
- The boiling point of water is set at 212 degrees
One degree in the Fahrenheit scale is indicated with the symbol 
.
The equivalence between temperature in Celsius degrees and Fahrenheit degrees is as follows:
to convert from Fahrenheit to Celsius
to convert from Celsius to Fahrenheit
The Fahrenheit scale is an increasing monotonic scale, it means that temperature goes from negative values towards positive values without interruption. Therefore, the temperatures listed from warmest to coldest are:
3°F, 0°F, -11°F, -16°F, -20°F
From my research and own thoughts I think D
alpha decay is an emission of ₂⁴He
nucleus. If an element undergoes an alpha decay, the mass of the daughter
nucleus formed is reduced by 4 compared to mass of parent atom and atomic
number is reduced by 2 compared to atomic number of parent atom.
Let's assume that the parent atom is X, atomic number is z and mass number is A. Then the formed daughter nucleus, Y should have atomic number as z-2 and mass number as A-4.
The equation is
(z) (A)X → ₂⁴α + (z-2)(A-4)Y
Example:
₉₄²³⁹Pu → ₂⁴α + ₉₂<span>²³⁵U</span>
Divide 180kg and 90m3 and your density will be 2kg/m3
