Raw milk is stored at a dairy farm in a refrigerated cylindrical vat 6.50 feet wide and 12.5 feet high. If the vat contains 3.3 × 10² ft³ of milk, how many kg of milk does the vat contain, given that raw milk has a density of 1030 kg/m3?

11.02 kg kg

Explanation:

From the question,

Density = Mass/Volume

D = m/v Equation 1

Let D = Density of milk in the vat, m = mass of the milk in the vat, v = volume of the milk in the vat.

Make m the subject of the equation

m = D/v Equation 2

Given: D = 1030 kg/m³, v = 3.3×10² ft³ = 330×0.2832 = 93.456 m²

Substitute these values into equation 4

m = 1030/93.456

m = 11.02 kg

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
