The impedance of transformer coil that has 600 feet is 10+j 22.62 Ω (ohms)
Explanation:
It is given that
a #22 copper wire has resistance= R= 10 Ω
inductance= I=0.06 H
N=60 HZ
X= 2π * N * I
=2 * 3.14 * 60 *0.06
X=22.62 Ω
Impedance is calculated by
Z = R + j * X
=10+ j (22.62 Ω)
Z= 10+ j 22.62 Ω
The impedance of a transformer coil that has 600 feet is Z= 10+ j 22.62 Ω

Hello. You forgot to provide the necessary text for this question to be answered. The text is:
On the risks that genetically modified foods also pose to humans. Many experts warn against genetically modified foods. Ronnie C. of the Organic Consumers Association warns: “We are using a new technology. We will face a problem if we don't look before we jump. "In addition, Dr. Mae Wan, a geneticist and physicist, warns that" genetic engineering is inevitably dangerous ".
Since almost half of the US corn and soybean crops are now genetically modified, we must act now. We do not know the health effects of these foods. So far, it is in everyone's interest to find better ways to feed the world.
Answer:
They support saying that genetically modified food is a very new technology that can be dangerous.
Explanation:
The text points to a possible danger of including foods that have been genetically modified in our food. This is because these foods are very controversial and may not offer benefits to our bodies.
To support this text, the author shows experts who claim that genetically modified foods come from a very new technology and should be further researched so that we are sure that we will not be harmed.
