An engineer writes a program to estimate the power output of a wind turbine.
wind_speed = float(input("Enter wind speed in m/s: "))
is_storm = input("Is a storm warning active? (Y/N): ")
efficiency = 0.85
if is_storm == "Y":
efficiency = 0.10
power_output = wind_speed * wind_speed * wind_speed * efficiency
print("Expected power output: ", power_output, " kW")
Identify two variables used in this program.
