      (1/5)
      1. What is the main reason to adjust the drone's speed during a mission?
      easy
      A. To save battery by flying as fast as possible
      B. To change the drone's color
      C. To make the drone hover in place
      D. To fly slower near obstacles for safety

      Solution

      1. Step 1: Understand speed control purpose

        Speed control helps adjust how fast the drone flies to match mission needs.

      2. Step 2: Identify safety reason

        Flying slower near obstacles reduces crash risk and improves control.

      3. Final Answer:

        To fly slower near obstacles for safety -> Option D

      4. Quick Check:

        Safety needs slower speed near obstacles = B [OK]
      Hint: Slower speed near obstacles means safer flight [OK]
      Common Mistakes:
      • Thinking faster speed always saves battery
      • Confusing speed control with hovering
      • Believing speed changes drone color
      2. Which of the following is the correct way to set the drone speed to 5 meters per second in code?
      easy
      A. setSpeed(drone, 5)
      B. drone.speed = '5mps'
      C. drone.setSpeed(5)
      D. drone.speed(5)

      Solution

      1. Step 1: Identify correct method syntax

        The method to set speed is called on the drone object with a number argument.

      2. Step 2: Check each option

        drone.setSpeed(5) uses drone.setSpeed(5) which is correct syntax for setting speed to 5.

      3. Final Answer:

        drone.setSpeed(5) -> Option C

      4. Quick Check:

        Method call with number argument = A [OK]
      Hint: Use object.method(value) to set speed [OK]
      Common Mistakes:
      • Using string instead of number for speed
      • Calling speed as a function instead of method
      • Passing drone as argument instead of calling method on it
      3. What will be the output of this code snippet?
      drone.setSpeed(3)
print(drone.speed)
      medium
      A. None
      B. 3
      C. Error: speed attribute not found
      D. drone.setSpeed(3)

      Solution

      1. Step 1: Understand setSpeed effect

        Calling drone.setSpeed(3) sets the drone's speed attribute to 3.

      2. Step 2: Print drone.speed value

        Printing drone.speed outputs the current speed value, which is 3.

      3. Final Answer:

        3 -> Option B

      4. Quick Check:

        Set speed to 3, print speed = 3 [OK]
      Hint: setSpeed changes speed attribute; print shows it [OK]
      Common Mistakes:
      • Expecting method call to print
      • Assuming speed attribute is missing
      • Confusing method name with attribute
      4. The following code is intended to set the drone speed to 10 m/s but causes an error. What is the problem?
      drone.setspeed(10)
      medium
      A. Method name is case-sensitive; should be setSpeed
      B. Speed value 10 is too high and causes error
      C. Missing parentheses after method name
      D. drone object is not defined

      Solution

      1. Step 1: Check method name spelling

        Method names are case-sensitive; 'setspeed' is incorrect, correct is 'setSpeed'.

      2. Step 2: Confirm other options

        Speed 10 is valid, parentheses are present, and drone object assumed defined.

      3. Final Answer:

        Method name is case-sensitive; should be setSpeed -> Option A

      4. Quick Check:

        Case-sensitive method names cause errors = A [OK]
      Hint: Check exact method name spelling and case [OK]
      Common Mistakes:
      • Ignoring case sensitivity in method names
      • Assuming value too high causes error
      • Forgetting parentheses after method
      5. You want the drone to fly slower near obstacles and faster in open areas during a mission. Which code snippet correctly changes speed based on distance to obstacle?
      distance = drone.getDistance()
if distance < 5:
    drone.setSpeed(2)
else:
    drone.setSpeed(8)
      hard
      A. Correctly sets speed slower near obstacles and faster otherwise
      B. Sets speed faster near obstacles, which is unsafe
      C. Uses wrong comparison operator; should be distance > 5
      D. Does not change speed at all

      Solution

      1. Step 1: Understand distance check

        Code checks if distance to obstacle is less than 5 meters.

      2. Step 2: Analyze speed settings

        If close (distance < 5), speed is set to 2 (slow). Else speed is 8 (fast). This matches safe speed control.

      3. Final Answer:

        Correctly sets speed slower near obstacles and faster otherwise -> Option A

      4. Quick Check:

        Distance check controls speed safely = C [OK]
      Hint: Use if distance < threshold for slower speed [OK]
      Common Mistakes:
      • Reversing comparison operator
      • Setting faster speed near obstacles
      • Not calling setSpeed inside condition
