A 10-kg object is pushed across a rough surface. It begins at rest and accelerates to a speed of 4 m/s in a distance of 5m. Which fact(s) support the conclusion that the object experiences an unbalanced force? A) The rough surface has friction. B) The object has a mass of 10-kg. C) The object accelerates across the surface. D) The object has a force applied to it and covers a distance.

C)The object accelerates across the surface.

Explanation:

its going to be mutualism cuz they both benefit from the relationship.

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.
