Trisha measured the volume of a cube using a
ruler. The length, width and
height all measured 8 cm.
The mass of the cube was
128 9. what is the density of
the cube? help

0.25

Explanation:

density = mass / volume

data given :

mass=128 g

volume of a cube = L *L *L (L is length)

=8*8*8

=512 cm³

density = 128/512

=0.25 g/cm³

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
