Controls or controlled variables are variables that should remain unchanged in the experiment. These variables can have a direct effect on the dependent variable. Take note that controlled variables are NOT what is being tested but can alter results. Three possible controls for this experiment would mainly be features of the ball and the ramp.
Examples and possible answers to your question would be:
1. Mass of the ball
2. Size of the ball
3. The density of the ball
4. Type of ball
5. Length of the ramp
6. Type of ramp
7. The thickness of the ramp

Other controls that you can consider also is the environment. Wind can also affect the ball that is being rolled.</span>
Of course! Why not? Explain why? Um, because girls are capable of doing things.
Okay thank goodness for the reason why I am not trying it out lol I love
According to the condensation theory, the most important factor for the formation of our planets was "the interstellar dust attracting heat away from the protosun".
Condensation is the procedure by which water particles noticeable all around bunch together and shape fluid water. This is regularly observed outwardly of cold glasses. This idea additionally identifies with the solar system.
The condensation theory of the solar system expresses that our solar system, and perhaps all other galaxies, were shaped from a cloud of residue and gas that consolidated into strong issue. Space experts trust that the littlest grains of residue in our cloud applied a draw on the gas about it, 'consolidating' into bigger and bigger bits of issue, similarly as a snowball moving downhill will become bigger and bigger. In the long run, the gravitational draw of these residue atoms was sufficiently solid that they started to pull in each other, developing into greater and greater clusters that had more grounded gravitational pulls. In the long run, these bunches of residue and gas from the cloud frame a star, and potentially planets, space rocks, and comets turning about the star.
C. Planet A orbits its star faster than Planet B.
Explanation:
since Planet A is closer to the star due to its gravitational force, it will orbit its star faster than planet B
hope this helps :)
