How can a boat move at constant velocity if it's propeller provides a steady force to it?
Terminal velocity, where the driving force = drag force from the water
Differentiate between steady flow and pipe unsteady flow?
The velocity is constant in a steady flow pipe while in the unsteady flow the velocity is not constant.
As long as an object travels in a straight line at a steady speed it velocity is what?
That's the definition of constant velocity. Also a good description of zero acceleration.
What is steady velocity?
Steady velocity means keeping the same speed. Like in "between the stations, the train maintained a steady velocity".
If a car drove a around in a circle would that be constant velocity?
No. Velocity is a 'vector', which means it's a measurement that has both magnitude and direction. The magnitude is what we usually call the 'speed'. For an object moving in a circle, it could have constant speed ... the velocity could have constant magnitude ... but there's no way the whole velocity vector could be constant, because the direction is always changing. Constant velocity is very easy to recognize ... the object is moving at a steady speed, in a straight line.

When velocity will be constant what will be the energy?
Kinetic energy will be constant, but total energy (KE+PE) might not be. If the car, say, is climbing a hill at a steady speed, its KE is constant, but the work done by the engine is being used to increase PE.
A glider sailing across the sky at a steady speed and altitude an example of and unbalanced force?
No. A glider that is moving at a constant speed and in a constant direction is at a constant velocity. In other words it is not accelerating. Therefore, all forces on it must be balanced.
Describe the motion of a bus whose acceleration is 0 but whose speed is not 0.?
The bus is in steady motion along a straight line at a constant velocity.
When are the 4 forces of flight equal?
The plane will fly at steady height and speed :)
What is the net force on a car traveling along a straight road at a steady speed of 100?
The term "steady speed" indicates a constant velocity. This implies that there is no net acceleration, and thus no net force. Any net force on a moving object will cause a change in velocity, as per Newton's First and Second Laws.
What is the acceleration of a car with a steady velocity of 100 km per hour for 100 seconds?
If velocity is steady and doesn't change, then there is 0 acceleration.
Why do electrons acquire steady drift velocity?
Electrons acquire steady velocity because the acceleration acquired is lost in collisions with positive ions of the metals.
