Calculate the density of rock that weights 14.5 kg and has a volume of 141 cm3 . Express your answer in g/cm3 .

102.83 g/cm³

Explanation:

Density = Mass/ Volume

Mass = 14.5kg

Volume = 141cm³

The answer is to be in g/cm³ so, convert 14.5kg to gram

1000g = 1kg

X = 14.5kg.

Now x = 14,500g

So we have mass as 14,500g

Recall that density = mass/volume, now you can plug your parameters

D = 14,500/141

102.83 g/cm³//

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
