Question

many mobile devices contain a(n) ___ and gyroscope that can sense even the smallest movements.
scanner
lbs
gps
accelerometer

Explanation:

To solve this, we analyze each option:

• Scanner: Used for scanning documents/images, not sensing movement. Eliminate.
• LBS (Location - Based Service): A service, not a hardware component for sensing movement. Eliminate.
• GPS: Used for location tracking (latitude/longitude), not for sensing small movements. Eliminate.
• Accelerometer: A sensor in mobile devices that, along with a gyroscope, detects small movements (like tilting, acceleration). This fits the context.

Answer:

D. accelerometer
