Astudent uses a magnet to move a 0.025 kg metal ball. the magnet exerts a
force of 5 n, which causes the ball to begin moving. what is the acceleration of
the ball when it begins to move?

The acceleration of the ball is 200 m/s².

Explanation:

Force:

Force is the push or pull on an object with mass that causes it to change velocity or to accelerate.

Force represents as a vector, which means it has both magnitude and direction.

Given:

Mass of metal ball = 0.025 kg

Force           = 5 N

To Find:

Acceleration, = ?

Solution:

Formula:

The acceleration of the ball is 200 m/s².

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.
