In the 1980s, Arthur Laffer proposed that the economy was operating around which point?
a. A
b. B
c. C
d. D
e. E
Given the answer to first question, what discretionary fiscal policy tool did Arthur Laffer propose that the United States utilize to increase tax revenues?
a. decrease government spending
b. keep income tax rates at the current level
c. decrease income tax rates
d. increase government spending
e. increase income tax rates
Answer:
c. C
c. decrease income tax rates
Explanation:
Arthur Laffer was a supply‑side economist who was interested in finding the optimal income tax rate that would maximize government tax revenues. This hypothetical tax rate would lead to the economy operating at point E. He is not known for his views on government spending, or demand‑side policies.
Laffer proposed that the U.S. economy in the 1980s was operating at an income tax rate that was too high, but it was not at 100%. Therefore, the answer to the first question is point C. Point C is above the optimal tax rate (point E), but lower than a 100% tax rate (point A).
Given where Laffer thought the economy was operating, he proposed that decreasing tax rates was the solution to increasing tax revenues. Therefore, the answer to the second question is to decrease income tax rates.

A bicycle wheel of known rotational inertia is free to rotate about its central axis. With the wheel initially at rest, a student wraps a string around the wheel and pulls the string with a spring scale, causing the wheel to rotate. The student records the tension in the string and the time for which the string was pulled. Without measuring the wheel’s final angular speed, can the student find the magnitude of the wheel’s final angular momentum, and what is a correct explanation?.
Yes but the student also needs to measure the wheel's radius to calculate the torque exerted on the wheel.
How to calculate final angular momentum?Mathematically, angular momentum is calculated by using any of these formulas:
L = Iω
ΔL = τΔt
Where:
L is the angular momentum.I is the moment of inertia or rotational inertia.ω is the angular speed.τ is the torque.Δt is the change in time.ΔL is the change in angular momentum.Since the torque wasn't provided, the student would have to measure the radius (r) of the wheel and multiply it by the tension (T) in the wheel. Thus, this is given by:
τ = rFsinθ = rT

Example, because I'm not sure I explained correctly: If a president is more left-leaning, they can (and probably will) appoint a left-leaning judge, so that they will judge matters as they or their political party would judge them. Appointing a judge with whom you disagree with isn't a strategic idea, because the president's ideals may be very different from a right-leaning judge. t-leaning, they can (and probably will) appoint a left-leaning judge, so that they will judge matters as they or their political party would judge them.
