A 5 g sample of pure gold has a density of 19.3 g/ml. your friend purchased a gold ring that was made of 25 g of pure gold. what is the density of the ring?

it has one origin of replication, but it proceeds in two directions - d)

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
