A) The calculated resistance needed to generate the current at low speed is; R = 480 ohms
B) Resistance at medium and larger speeds are;
At medium speed; R is less than that at low speed
At larger speed; R is less than that at medium speed.
A) We are given;
Voltage; V = 120 V
Current at lower speed; I = 0.25 A
Formula for resistance here is;
R = V/I
R = 120/0.25
R = 480 ohms
B) This means that if larger currents are required at higher speeds, it means that lower resistance would be required.
Similarly at medium currents the resistance will be lesser than that at lower speed but greater than that at larger speeds.

Answer:
Answer: D
GDP per capita is a measure of a country's economic output that accounts for its number of people.
The unemployment rate is defined as the percentage of unemployed workers in the total labor force.
The infant mortality rate is the number of deaths under one year of age.
Given the above information, a country with a higher GDP would have a more stable economy aiding in growth. A lower unemployment rate would show a surplus of jobs indicating, once again, a steady and growing economy. Lastly, a lower infant mortality rate would show access to advanced medicine and a highly trained medical field. All three of these examples are indicators of a highly developed country.
Explanation:
B. On test day, you will record your responses to the tests on your answer document. After testing is completed, your test coordinator will send your answer document to ACT. Score reports will normally be mailed about 2–8 weeks after they receive your answer document.
