Natasha measures the masses of three objects and records her results in the table. What should Natasha do next to determine the densities of the objects?
She should measure the circumference of each object
She should measure the temperature of each object.
She should measure the volume of each object.
She should measure the surface area of each object.

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
