A piece of wood of mass 300 g has a volume of 400 cm3
Find the density of the wood.

0.75 g/cm³

Explanation:

FORMULA

Density=mass/volume

Given: mass is 300 g, volume is 400 cm³

Density=mass/volume

Density=300/400

Density=3/4

Density=0.75 g/cm³

Hope this helps!! :)

Please let me know if you have any question

Density = 0.75 g/cm³

Explanation:

we know the formula of Density,

Density = Mass / Volume

So,

Density = 300 g /400 cm³

Density = 0.75 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.
