Answer:
ANSWER KEY Relationship of Magnets CER
Claim (Write one sentence stating the cause and effect relationship of magnets.)
In magnets, like poles repel, whereas opposite poles attract.
Evidence (Provide scientific data to support your claim. The evidence should include how attraction and repulsion is demonstrated by the matchbox cars and the position of the poles of the magnets.)
When the North Pole of the magnet (orange) and the South Pole of the magnet (green) came close to one another they attracted and when the North Pole of the magnet (orange) and the North Pole of the magnet (orange) came close to one another, they repelled. The South Pole against the South Pole repelled as well. Therefore confirming that opposite poles attract and like poles repel. We were able to record data to show the distance that each car traveled by using either attraction or repulsion. Four out of five cars give evidence that the repulsion, created by opposing poles, had the stronger force.
Reasoning (Explain why your evidence supports your claim. Describe how the poles of the magnet determine whether magnets attract or repel and how your evidence allowed you to see the force of the attraction or repulsion.)
Magnets have an invisible force around them, called the magnetic field, which has North and South Poles. The opposite poles attract and like poles repel. We saw this through completing the activity by seeing and measuring the distance that was traveled by each car using attraction and repulsion.
The answer is C because thats what the answer is so good luck in the class
Answer:
Heat or thermal energy!!!
Explanation: When heat is added the particles speed up at rapid rates causing the state of the object to change nd in order to melt it must be heated.
Answer:
Object 2 has the larger drag coefficient
Explanation:
The drag force, D, is given by the equation:
Object 1 has twice the diameter of object 2.
If 
Area of object 2, 
Area of object 1:
Since all other parameters are still the same except the drag coefficient:
For object 1:
For object 2:
Since the drag force for the two objects are the same:
Obviously from the equation above, c₂ is larger than c₁, this means that object 2 has the larger drag coefficient
