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)
If the tip of an electrical overshoe is torn
- it may be cut back.
- it may be classified as acceptable damage.
- it must not be cut back.
can someone explain this, i dont get what the question means by "cut back"
The blood/alcohol limit is
- 40 milligrams of alcohol per 100 millilitres of blood as the single universal limit applying equally to commercial aircrew, air traffic controllers and all maintenance engineers.
- 20 milligrams of alcohol per 100 millilitres of blood as the single uniform limit for commercial aircrew, air traffic controllers and licensed aircraft maintenance engineers alike.
- 20 milligrams of alcohol per 100 millilitres of blood for commercial aircrew, air traffic controllers and 80 milligrams of alcohol per 100 millilitres of blood for maintenance engineers.
at my knowlegde second answer is correct? is it?
