A car is running at a constant speed of 50 km/h, which of the following is the feedback element for the driver ?

Clutch
Eyes
Needle of the speedometer
Steering wheel E. None of the above

The correct answer is C. Needle of the speedometer.

The speedometer is a device that measures the speed of a vehicle. It is usually located on the dashboard of the car, and it has a needle that moves up and down to indicate the speed. The needle of the speedometer is the feedback element for the driver because it tells the driver how fast the car is going.

The other options are not feedback elements for the driver. The clutch is a device that connects and disconnects the engine from the transmission. The eyes are used by the driver to see the road and other vehicles. The steering wheel is used by the driver to steer the car. None of these things provide feedback to the driver about the speed of the car.
