1) There are always frictional forces, which by themselves would slow the car down.
2) Since we are assuming that the car is moving at a uniform speed, there must be another force to compensate for the friction, and in the opposite direction (pulling the car forward). This force is related to the effort done by the engine.
It would not be a perfect answer if I said yes because you did not assume that if the body was moving in vacumn. If its not, like for example it is moving on an ice block on the surface of the earth then the object still has gravity and the air friction acting on it. Even the molecules of the ice's surface attract the surface of that object it is in contact with. So if I say that the object is in space then it would be a incredibly correct answer to say yes, there are no force acting on the body.
A smooth surface will appear uniform and featureless under a microscope, without any visible bumps or irregularities. The surface will reflect light evenly, creating a flat and consistent appearance in the magnified image.
Antaganism
An object moving at a constant speed in a straight line will have a uniform motion without any change in speed or direction. The motion will appear smooth and consistent, with the object covering equal distances in equal time intervals.
The coefficient of friction between a perfectly smooth body and a very rough body would be close to zero because a smooth body has no surface irregularities to create friction with the rough body. Friction occurs due to the interaction of surface irregularities, so if one surface is perfectly smooth, there would be minimal friction.
It is perfectly smooth.

deft: adjective: moving or acting in a quick, smooth, and skillful way; clever, showing good sense and skill in achieving or acquiring things.
If it is perfectly smooth then only sliding friction.
Because on the molecular level, they are not smooth No surface is perfectly smooth and even if it were, many molecules of the two surfaces would get close enough together to interact.

Toner can be used in the process of making ferrofluid by acting as a surfactant to help disperse the magnetic nanoparticles in the liquid. This helps to stabilize the particles and prevent them from clumping together, creating a smooth and uniform ferrofluid mixture.

For Earth to become a perfect shape, it would need to be perfectly spherical. This would require it to have a uniform distribution of mass and no geographical features like mountains or valleys. Achieving a perfectly spherical shape would mean Earth would have to be completely smooth and free of any irregularities.
