A thin square sheet of lead measuring 2.5 inches on each side weighs 525 mg. Find the thickness (in mm) of the sheet, given the density of lead to be 11.342 g/cc. (1 inch = 2.54 cm)

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

the answer is a for sure mark brainliest i had got this right on usatestprep

c) should be the answer.

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.
