If the average velocity o nonzero for some time interval does this mean that the instantaneous velocity is never zero during this interval?

Not at all. Consider this example: -- I start out at 8:00 in the morning. -- I head east, drive 5 miles in 15 minutes, and park my car at 8:15. -- I go into my office, close the door, and spend the next 9-1/2 hours on Wiki.Answers. -- I leave the office exhausted at 5:45 in the evening. -- I head east again, drive another 5 miles in the next 15 minutes, and stop at a bar at 6:00. ==================================================== I left home 10 hours ago, and I am now 10 miles east of my home, enjoying a tall cold one. My average velocity for the 10 hours is 1 mile per hour east. The average is non-zero, even though I was at my desk playing computer games from 8:15 until 5:45. At any instant during 95% of the day, my instantaneous velocity was zero.

Can you have zero displacement and nonzero velocity?
i will give u an illustration, consider an object projected (thrown)with some initial vertical velocity from the ground such that it traces a open downward parabolicpath, in that path the vertical displacement of the body from the point of projection to the point where it strikes the ground is equal to zero,but it have some velocity.
What happens to an object in motion when it experiences a nonzero net force?
its velocity will change by accelerating in the direction of the force
Which encoding type always has a nonzero average amplitude?
polar
Can object have zero acceleration and nonzero velocity at the same time.give example?
Yes, for example, a car moving at constant speed.
Why can velocity be negative but nonzero speed is always positive?
speed is a scalar quantity with magnitude only but no direction; velocity is a vector with both magnitude (speed) AND direction, which could be positive or negative
Can you have a nonzero average velocity?
Yes. As long as the inital and end positions are different, you will have a nonzero average velocity.

Can a body have nonzero average speed but have zero average velocity give example?
An object moving in a circular path at constant speed will have a non-zero average speed and zero average velocity since velocity is a vector parameter,
What object has velocity?
Any object which moves has velocity.Velocity is a vector quantity which includes direction so the object's velocity will change at every point in time if there is a nonzero acceleration.An object going around in circles uniformly will have a zero average velocity when measured as displacement over a time interval if the time interval is a multiple of the period of revolution. Speed is similar to velocity but is a scalar quantity independent of direction; you can think of it as distance covered traveling per unit of time; that is what your speedometer measures.

How does vector calculus apply in fluid mechanics?
The velocity at each point in the fluid is a vector. If the fluid is compressible, the divergence of the velocity vector is nonzero in general. In a vortex the curl is nonzero.
Can a body have zero velocity with nonzero accelaration?
Yes, but only for an instant.
What is the time limited signal?
A time limited signal is one that is nonzero only for a finite length time interval.
Is it possible that a body has zero speed and nonzero velocity?
No because velocity defined as speed in a given direction so if speed is 0 then velocity must also be 0
What happens to an object in motion when it experiences a nonzero net force?
its velocity will change by accelerating in the direction of the force
Which encoding type always has a nonzero average amplitude?
polar
Can an object have zero velocity and nonzero acceleration?
Yes. An object moving at constant velocity has zero acceleration. The constant velocity van be any constant including zero velocity. Mathematics acceleration a=dv/dt = 0. Solving this gives v = constant.
