It doesn't matter what the car's mass is, or for that matter, what speed you're talking about.
If the total forces opposing its motion are 800 N, then you need to supply 800 N in the direction
of motion in order to maintain a constant speed.
It can, but it won't always. In other words, if the speed is constant, the velocity may, or may not, be constant as well.
Never, since "vertical" means directly opposing the local gravity field.
Newton's 1st Law of Motion states that an object will maintain its speed when there is no net force acting on it. The question refers to free space and constant velocity -- the net force has to be zero. =========================
Multiplication of wavelength and frequency is equal to velocity of the wave.It is a constant in a medium.So wavelength and frequency is indirectly propotinal.One should increase if other decrease to maintain the constant velocity.
In that case, the velocity is said to be constant.

A changing velocity can maintain constant speed if the motion is circular. The constant change in direction is a change in velocity, even if the speed is constant.
constant velocity is when you maintain speed and direction, this usually is in a straight line, and constant speed means that your speed is always constant at all times.

If it wasn't for forces acting opposing to the direction of motion, an object would continue to move in a given direction at constant speed (constant velocity) indefinitely without the need of a force exerting on it.<br><br>However due to "real world" forces such as friction or air resistance, a force equal and opposite to these opposing forces needs to be applied to an object to keep it moving at constant velocity.<br><br>These are all governed by Newton's Laws of Motion.<br>
As we know that Kepler's laws of planetary motion state that aerial velocity of a planet remains constant i.e dA/dt = constant , Where A is the area swept by the planet around sun. so to maintain the aerial velocity constant,planet has variable velocity.
This is a very broad question since there are many different types of homeostasis. It is possible to maintain a constant temperature, or a constant location, or a constant pH, or a constant velocity, or a constant luminosity, etc. etc. Without knowing what parameter you are concerned about, there is no point in describing a method of obtaining homeostasis.

Yes. Zero velocity is a velocity; if it is always zero then it is a constant velocity.
In that case, the velocity is said to be constant.
If your velocity is constant, then your acceleration is zero.
