The solid material that is left behind in the distillation process is called the residue.
Distillation is the separation technique that involves the separation of two liquids with different boiling points.
The residue is the solid.part of a mixture after all other components of the mixture has been removed.
During the distillation process, after the heating of the mixture, the more volatile liquid changes to vapour.
The vapour is cooled by passing it through a condenser and collected in a liquid form known as distillate. while residue is left behind in a flask.
Therefore, the solid material that is left behind in the distillation process is called the residue.

Answer:
The solid, called the residue, will be left behind in the filter paper while the liquid, called the filtrate, will pass through the filter paper.
Explanation:
1. A teacher challenges.students to study moon phases to determine if what they have learned from the textbook is accurate. How might a student investigate claims made in a textbook that moo. phases occur in a 28-day cycle?
A. observe the phase of the moon each night until a full moon can be seen.
B. Compare the textbook phases to the actual moon phases seen in the night sky each night in 28 days periods over a three month time frame.
C. Compare diagrams of moon phases from the textbook to diagrams of moon phases on-line
D. Observe the moon phases seen in the night sky as often as possible over a six month period.
2. What causes the apperance of the moon change overtime?
A. The orbit of the Earth around the Moon and its distance from the sun.
B.The Moons position relative to the sun and earth as it revolves around sun.
C. the rotation of the moon on its axis
D. The distance of the moon to the sun

Answer:c
Explanation:
force of gravitation between two different masses is given by
here in first case we will have
Newton
another case we have
Newton
another case we have
Newton
so the force will be maximum in last case when two 2 kg mass is placed at 1 m distance and minimum force is in second case when 1kg and 2kg mass is placed at 2 m distance
Answer:
1 . rays should passs through correct center or points(i.e. optic center or focus)
2.your line representing rays should be straight and u should tell the nature of image
Explanation:
The net force of an object moving with constant speed in a circular motion is in tangential direction​.
Uniform circular motion is a type of motion of a particle around a circle at a constant speed. The magnitude of the speed of the particle is constant.While the direction is changing continuously.
Kinetic energy, acceleration, and displacement of the following is constant for an object in uniform circular motion.
Hence,the net force of an object moving with constant speed in a circular motion is in tangential direction​.
