help me pls
The relationship between induced drag and airspeed is, induced drag is
- directly proportional to the square of the airspeed.
- directly proportional to airspeed alone.
- inversely proportional to the square of the speed.
Induced drag results from production of lift. Lift depends on airspeed squared, not 1 over airspeed squared.
Total resistance in a parallel resistor circuit, of R1 and R2 is
- RT = 1/R1 + 1/R2.
- 1/RT = (R1 * R2) ÷ (R1 + R2).
- 1/RT = 1/R1 + 1/R2.
i think the answer here is wrong! the true answer is RT = (R1 x R2) ÷ (R1 + R2)
