The acceleration of the car is 0 m/s^2 because it is moving at a steady velocity, meaning there is no change in its speed over time. Acceleration is the rate of change of velocity, which is not occurring in this scenario.
If the car doesn't change direction during that 100 seconds, then it's zero. If the car's direction changes, then the acceleration isn't zero, but the question doesn't give any information from which to evaluate it.
It velocity is constantly increasing, v=vo + at.
The relationship between velocity and acceleration affects how an object moves. When acceleration is positive, velocity increases, causing the object to speed up. When acceleration is negative, velocity decreases, causing the object to slow down. If acceleration is zero, velocity remains constant, and the object moves at a steady speed.
An object moving with uniform acceleration has a uniform change in velocity over time, and its velocity-time graph will be a straight line with either a positive or negative slope. An object moving with no acceleration has constant velocity, and its velocity-time graph will be a straight, horizontal line with zero slope. Refer to the related link for illustrations.
Changing velocity affects acceleration because acceleration is defined as the rate of change of velocity. If an object's velocity increases, its acceleration is positive. If the velocity decreases, the acceleration is negative. The magnitude of the acceleration depends on how quickly the velocity changes.
Acceleration = 0 because the car is moving at a STEADY velocity. It is neither speeding up, nor slowing down.
If the car doesn't change direction during that 100 seconds, then it's zero. If the car's direction changes, then the acceleration isn't zero, but the question doesn't give any information from which to evaluate it.

Acceleration is the time rate of change of velocity. If velocity is constant, then acceleration is zero. Note: "100 km per h for 10 seconds" is a constant speed, but not necessarily a constant velocity, since we're told nothing about the direction. If the car moves in a perfectly straight line during those 10 seconds, then its velocity is constant. If it makes a curve, then its velocity is not constant even though its speed is, and there is acceleration.
There is only acceleration if the car's velocity changes. If it moves at a constant velocity, then there is no acceleration.

An object moving with no acceleration has constant velocity, and its velocity-time graph will be a straight, horizontal line with zero slope. Refer to the related link for illustrations.
The velocity increases at a constant rate.
Changing velocity affects acceleration because acceleration is defined as the rate of change of velocity. If an object's velocity increases, its acceleration is positive. If the velocity decreases, the acceleration is negative. The magnitude of the acceleration depends on how quickly the velocity changes.
The velocity of an object moving in a circular path will change because the direction of the velocity vector is constantly changing. This change in velocity indicates that there is acceleration present, known as centripetal acceleration, which always points towards the center of the circular path.
When velocity changes, that means that the object either moves faster, or moves slower, or moves in a different direction. Any of these changes is called "acceleration". A force is necessary to cause it.
When velocity changes, the speed and/or direction of an object's motion is altered. This can result in acceleration or deceleration, depending on the direction of the change in velocity. If the velocity increases, the object is accelerating; if the velocity decreases, the object is decelerating.
