Front

This is known as . . .

Back

Medium Motor Block

Answer explanation

The correct answer is 'Medium Motor Block' as it specifically refers to a type of block used in motor control applications, distinguishing it from other options like 'Large Motor' or 'The Claw Block'.

Front

When would you use this block?

Back

When you need to read the Data from the Ultrasonic Sensor

Answer explanation

You would use this block when you need to read data from the Ultrasonic Sensor, which is essential for measuring distances and detecting objects, making it the correct choice.

Front

What sensor is being used in this program?

Back

Ultrasonic Sensor

Answer explanation

The program uses an Ultrasonic Sensor to measure distance by emitting sound waves and detecting their reflection. This makes it the correct choice, as it specifically identifies the type of sensor being utilized.

Front

Which programming code will stop the robot 20 centimeters from an object?

Back

Front

Without the "start" block the program will not be able to move.

Back

True

Answer explanation

The 'start' block is essential for initiating movement in the program. Without it, the program lacks the necessary command to begin, making the statement true.

Back

Gyro Sensor

Answer explanation

A gyro sensor detects angular velocity and orientation, making it suitable for applications like motion tracking. The other options (sound, touch, light sensors) serve different functions, confirming that the correct answer is a gyro sensor.

Front

What is this block called?

Back

Move steering

Answer explanation

The block is called 'Move steering' because it specifically refers to controlling the direction of movement, unlike the other options which do not pertain to steering functionality.
