John Kepler made significant contributions to optics and geometries. Options 2,4 and 5 are the statement that shows the contribution of Johannes Kepler.
What are the contributions of Johannes Kepler?Johannes Kepler was indeed an astronomer and mathematician who finds the planet's elliptical orbits around the sun.
He identifies three basic rules of planetary motion. He also made significant contributions to optics and geometries.
Following are the contributions of Johannes Kepler;
2. He solved Ptolemy’s model by proving elliptical orbits.
4. He determined that planets move faster when closer to the Sun.
5. He discovered the laws of planetary motion.
Hence options 2,4 and 5 are the statement that shows the contribution of Johannes Kepler.

The blue mass in the image is 10kg.
The red mass in the image is 10kg.
The blue mass is currently 4 meters away from the red mass.
If we change each mass to 20kg, what will happen to the gravitational force each mass puts on the other?? You have to pick a answer through A,B,C! The force of gravity will increase as the masses increase.
The force of gravity will not change as the masses increase.
The force of gravity will decrease as the masses increase.
What is most likely to occur during a chemical reaction
Answer/Explanation:
In a chemical reaction, the atoms and molecules produced by the reaction are called products. ... No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
This question involves the concepts of a chemical reaction, conservation of mass, chemical bonds.
During a chemical reaction, the phenomenon that is most likely to occur from the given phenomena is "Mass is conserved".
Whenever a chemical reaction occurs old bonds between the elements are broken and new bonds are formed amongst different elements. Hence, the properties of the original substances are changed due to the formation of new bonds, and new molecules as a result.
Original molecules or substances are lost due to formation of the new ones.
No new atoms are created or destroyed in a chemical reaction. The atoms just rearrange themselves to form new molecules or substances only.
Since no atoms are created or destroyed during a chemical reaction. Hence the law of conservation of mass is applicable to a chemical reaction. This means the mass is conserved during a chemical reaction.

Amy's average speed is twice Chris's average speed.
Chris's average speed is twice Amy's average speed.
Amy's average speed is equal to Chris's average speed.
Chris's average speed is three times Amy's average speed.
Answer:
Amy's average speed is equal to Chris's average speed
Answer:
im pretty sure its 'a'
Explanation:
Amy took 1 more point than Chris and reached their destination in 2 Hrs. when Chris took less and reached the destination in 3 Hrs.

Venn diagrams are used for comparing and contrasting different topics. The overlapping sections show characteristics that the topics have in common, and the sections that are unique to each topic show the characteristics apply to only that topic.
Overlapping circles are labeled solid on top, liquid at right, gas at left, with the intersection of all three labeled state of matter.
Which Venn diagram accurately describes what characteristics of solids, liquids, and gasses could be added to this diagram?
Overlapping circles are labeled definite shape most dense at top, mid-level density at right, definite volume least dense at left, with the intersection labeled state of matter.
Overlapping circles are labeled definite shape most dense at top, mid-level density at right, least dense at left, with the intersection of all three labeled state of matter. The intersection of the top and right circles is labeled definite volume.
