absence
of the trait.

the real answer is b. scintillation counter

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

c. heat from the poles back down towards the equator.

ask your friends for what they got then copy it down if you don't have any friends which is fine than google it or pay the teacher
