What else can I help you with?
Can a body have nonzero average speed but have zero average velocity give example?
Yes, a body can have a nonzero average speed but zero average velocity if it moves around a closed path and returns to its starting point. For example, if a car travels around a circular track at a constant speed, its average speed will be nonzero (as distance is covered), but its average velocity over the entire trip will be zero as the displacement is 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.
Can a situation exist in which an object has zero acceleration and nonzero velocity even for an instant?
No, if an object has zero acceleration, its velocity cannot be changing. If the velocity is nonzero, it must either be increasing or decreasing, which requires acceleration.
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.
Can an object have zero velocity and nonzero acceleration?
Yes, an object can have zero velocity and nonzero acceleration. This occurs when the object is changing its direction but not its speed. For example, in circular motion, the object's velocity is constantly changing direction, leading to a nonzero acceleration even when its speed is constant.
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
When average velocity and average speed is equal?
For the instantaneous value of average velocity, average speed and average velocity are equal.
Which encoding type always has a nonzero average amplitude?
Pulse-position modulation (PPM) encoding type always has a nonzero average amplitude. In PPM, the signal's average amplitude is determined by the positioning of the pulses within the signal. This ensures that there is always a nonzero amplitude level in the signal, even during silent periods.
How is velocity different from average speeed?
Velocity is speed and its direction. Average velocity is average speed and its direction.
How does the velocity of an object traveling in a straight line change if a nonzero net force acts in the same direction as the objects velocity?
If a nonzero net force acts in the same direction as the object's velocity, the object's velocity will increase over time. This is because the force accelerates the object in the same direction as its motion, causing it to speed up.
Do you agree with the statement an object with a zero velocity can have an acceleration greater than zero do you agree?
Yes. If it weren't so, an object that isn't moving could never be made to move at all! Of course, once you apply acceleration (which implies a change of velocity), the object's velocity won't stay zero. But for a brief instant, the velocity can be zero while accelerating.
