Iron has a mass of 7.87 g per cubic centimeter of volume, and the mass of an iron atom is 9.27 × 10-26 kg. If you simplify and t
Talja [164]
<span>(a) what is the average volume (in cubic meters) required for each iron atom
For this case, the density of Iron would be </span>7.87g/cm³
<span>
V = 9.27 x 10^-26 kg / </span>7.87g/cm<span>³ ( 1 kg / 1000 g)
</span>V = 1.18 x 10-23 cm³<span>

(b) what is the distance (in meters) between the centers of adjacent atoms?
We assume the atoms as cube, so we use the volume of the cube to calculate the distance of the atoms.

V = </span>1.18 x 10-23 cm<span>³ = s</span>³
s = 2.28 x 10^-8 cm

Kedrick and Kaleb train by pushing a sled that weighs 300 kg at an acceleration of 2m/s^2. What force did they push the sled wit
stiks02 [169]

Answer:

\boxed {\tt 600 \ Newtons}

Explanation:

Force can be found by multiplying the mass and the acceleration.

F=m*a

The mass of the sled is 300 kilograms and the acceleration is 2 meters per second squared.

F= 300 \ kg * 2 \ m/s^2

Multiply.

F= 600 \ kg * m/s^2

1 kilogram-meter per second squared is equal to 1 Newton. Therefore, 600 kilograms-meter per second squared is equal to 600 Newtons.

F= 600 \ N

The force used on the sled is 600 Newtons.
