A balloon rises at a rate of 2km hr what it velocity?

That's the velocity.


How might speed at which a gas particle moves affects how quickly that gas particle escapes from the balloon?

Flow rate is diameter of hole*velocity, so the higher the velocity the higher the flow rate.


At what rate does the Earth revolve?

The angular velocity of Earth is 15 degrees an hour, 360 degrees over a 24 hour period.


What is rate of acceleration?

The rate of change of velocity. (As velocity is the rate of change of position.)


What is the rate of Chang of velocity?

The rate of change of velocity is acceleration.


What is the definition of rate of change of velocity?

The definition of rate of rate of change of velocity is Velocity is the rate of change of the position of an object, equivalent to a specification of its speed and direction of motion, e.g. 60 km/h to the north. Velocity is an important concept in kinematics, the branch of classical mechanics which describes the motion of bodies.


What is the rate velocity changes?

The rate of change in velocity is known as acceleration.


What is the rate of charge of velocity?

I think you mean the "rate of CHANGE" of velocity. (If you don't, then the question is meaningless.) The rate of change of velocity is called " acceleration ".


The rate at which velocity is changing is?

Acceleration and it is defined as the rate of change of velocity with time.


What is aceleration velocity?

"Acceleration velocity" is a meaningless phrase. "Velocity" is the time rate of change of position. "Acceleration" is the time rate of change of velocity.


Does high velocity affect rate of change of velocity?

No. The rate of change of an object's velocity depends only on the forces acting on it.


Why is acceleration zero with uniform velocity?

Uniform velocity means the velocity is not changing. Acceleration is defined as the rate of change of velocity. If velocity isn't changing, the rate of change is zero.
