What does EV3 Ultrasonic Sensor measure?

Sensor detects the ambient noise level

Sensor emits laser and calculate distance based on the time taken for the laser to travel from the sensor and reflect back to the sensor from the nearest object

Sensor emits laser and calculate brightness of the room based on the changes in light intensity of the laser reflected back to the sensor from the nearest object

Sensor emits sound and calculate distance based on the time taken for the sound to travel from the sensor and reflect back to the sensor from the nearest object

None

Student A have programmed the robot to spin in place, but the robot rotates around the right wheel instead. What should the student consider doing to fix the problem?

Check that the cable connected to the right motor is properly connected in the lettered ports then try to run the program again

Try running robot on a different surface

Rotate the robot and try to run the program again

Programming software is faulty, reinstall the software again

None

Which of the following is true about the Colour Sensor?

It cannot detect light intensity

It can detect when there is no color

It can be programmed to detect distance

None

Which sensor is most appropriate for detecting room light intensity?

Colour Sensor

Ultrasonic Sensor

Gyro Sensor

Touch Sensor

None

Which of the program tells the robot to move forward as long as there are no obstacle 5 cm away from the robot?

None

Sensors can be plugged into the EV3 CPU _____

None

Given the following program, under what condition will the robot drive forward?

If the Ultrasonic Sensor detects an obstacle lesser than 15cm away

After the robot drove backwards

If the robot drove backwards

If the Ultrasonic Sensor detects an obstacle 15cm or further in front of the robot

None

Given that the left motor is connect to Port A and right motor is connected to Port C, what will happen when this program runs?

Robot will rotate around the wheel of the right motor

Robot will spin in place

Robot will move forward

Robot will rotate around the wheel of the left motor

None

What does Gyro Sensor measure?

The stability of the robot

The amount the Gyro Sensor has rotated in the direction(s) indicated by the arrows on the sensor

The speed at which the robot is moving

Strength of the magnetic field around the sensor

None

10.

Which of the following is true about the difference between hold position and float?

Hold position stops the motor immediately while float allows the motor to move due to momentum

Hold position allow the motor to move due to momentum while float stops the motor immediately

None
