Can the car accelerate if the speedometer of a car indicates a constant speed?

no. see the definition of acceleration. it can remain a constant speed while the velocity changes.
*Edit* Actually, the answer is yes. The algebraic formula for acceleration is displacement over time but you are only thinking in terms of linear motion, or in the case of this scenario, a straight road. But when the car follows the road as it snakes or rounds a bend its acceleration is changing even if its speed is not.
A more specific definition of acceleration is the change in velocity over the change in time. Velocity is a measurement of speed but with a direction and when an object goes into a circular motion path (or any motion path that isn't linear) its velocity is continually changing and a change in velocity means a change in acceleration.
Plainly put, if the car turns a corner with a constant speed, the magnitude is constant but the acceleration vector is not.

Does a car accelerate when it goes around a corner at a constant speed?
yes an acceleration is a change in speed and when you go around a corner you change your speed.
CAN AN Object accelerate and be moving at a constant speed?
Yes, it's direction may be constantly changing which would mean it is still accelerating.
What does horizonal line on a speed timev graph indicate?
A horizontal line on a speed vs time graph indicates constant speed.
Is it true that a straight diagonal line on a distance versus time graph indicates a constant speed?
Yes. The slope, or rate, is constant. The rate being represented is speed. If the slope is a negative constant, the object is losing distance (going towards) from the orgin at at a constant speed.
Why does a constant speed have a slope of 0 on a graph of speed v time?
Because a slope of zero indicates that the y-value (speed) isn't changing.
An instrument which indicates the speed of a motor vehicles is?
It is a speedometer.
Indicates speed vehicles?
Speedometer
What does a speedometer do in a car?
It indicates the speed of the car.
What indicates the speed of vehicle?
That would be called the speedometer.
What is the indicates speed of vehicle?
That would be called the speedometer.
How can a car accelerate if its speed is constant?
It can Accelerate by changing it direction as acceleration eing a vector is dependant on the direction so by changing its direction one can accelrate it keeping the speed constant.
Does an object accelerate if it moves in a straight line at constant speed?
no
Does a car accelerate rounding a curve at a constant speed?
Yes
Does a straight line on a motion graph indicates constant speed?
Yes. A straight line indicates constant speed =dy/dt= kt.
Does light accelerate?
No. As long as it stays in the same material, its speed is constant.
How can an object accelerate if it is moving at a constant speed?
by adding more force
Can the car accelerate if the speedometer of a car indicates a constant speed of 40km per hour?
Acceleration is the derivative of velocity, meaning a change in velocity. Velocity is a vector, comprised of magnitude and direction, that is speed and where you are heading. Thus, turning, changing lanes, flipping the car while on cruise control, etc, would all comprise a change in velocity (specifically the direction) and thus is an accelaration.
