Read the excerpt from "Healthy Eating."

But no one can ignore the damage being wrought by all this bad eating. More than one out of three adults in the United States -- 37.5 percent -- are obese, according to the Centers for Disease Control and Prevention. Some of the leading causes of death -- heart disease, stroke and type 2 diabetes -- are directly linked to obesity. And childhood obesity has tripled in the last 30 years. With more than a third of kids between 6 and 19 considered obese, the CDC reports, they are at substantially more risk for developing cardiovascular disease, diabetes, bone and joint conditions, and cancer.

The author's argument that a poor diet can be harmful to a person's health is _____________________.

ineffective, because it lacks clear and reasonable evidence.

ineffective, because it leaves the reader with questions.

effective, because it addresses and refutes a counterclaim.

effective, because it includes facts from a credible source.

Plz help, its an emergency, giving lots of points for it. and srry if its in the wrong subject, not really sure? I just don't understand it at all, it's about atoms and all that stuff.

If an object has a positive charge, are the electrons from another object more likely to be attracted to it or to repel it?

Pick one of the statistics shared that does not fit your current paradigm and share how you think you would feel if it was part of your own reality?

Electric Charge (guided inquiry)
Purpose: To show how matter becomes charged by induction
Materials: comb, sink with working faucet

Predict: Predict what you think will happen to the charges of the comb and water if the comb comes in contact with the water. Record your hypothesis before following the directions below to carry out the lab experiment. The charges would attract. How and why is what I don’t know.
Directions:
1. Turn on a faucet just enough to allow a thin stream of water to flow.
2. Have a student volunteer-run a comb through his/ her hair a few times.
3. Observe. Tell the student to hold the comb near, but not touching, the stream of water.
4. Answer all questions below in complete sentences, using the R.A.C.E. strategy.
Ask and record your findings: What do you observe? Describe. I observed the stream of water bend toward the comb. I gave the comb electric charge by passing a comb through my sister’s hair and that allowed the comb to bend the stream of water.


Ask and record your findings: What does this indicate (show)? Explain. I

Written response please read all and answer in complete sentences will give BRAINLIEST
Observe:
1. To test students’ predictions, have the student volunteer pass the comb through the water.
2. Then have them move the comb so that it is near but not touching the water.
Ask and record your findings: What do you observe? Describe. WILL GIVE BRAINLIEST

Kinetic Energy problems
Formula: KE = ½ mv2

2. What is the Kinetic Energy of a 100 kg object that is moving with a speed of 20 m/s?


3. What is the Kinetic Energy of a 250 kg object that is moving with a speed of 15 m/s?


4. What is the Kinetic Energy of a 15 kg object that is moving with a speed of 30 m/s?


5. What is the Kinetic Energy of a 100 kg object that is moving with a speed of 12.5 m/s?

Please complete this in 3-5 sentences.

Now use the temperature change simulation to carry out your experiment. Record your data, as well as any necessary calculations, in the table. You can modify the table, if necessary, so it matches your experimental procedure.
