An astronomer wrote down the following observations regarding an object she recently discovered. Which piece of evidence disqualifies this object from being a planet? The object orbits a white dwarf star. The object also appears to have six moons of its own. Current images show that the object is rectangular in shape, and its mass is about one-fourth that of Earth’s. It has a slow orbital period, orbiting its star every 400 days.

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

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.
