Hannah has information about an object in circular orbit around earth.

mearth = 6.0 × 1024 kg

g = 6.67 × 10–11 startfraction m superscript 3 baseline over kilograms times s superscript 2 baseline endfraction.

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

brain development. a child's brain undergoes an amazing period of development from birth to three—producing more than a million neural connections each second. the development of the brain is influenced by many factors, including a child's relationships, experiences and environment.
