What is the minimum stream velocity needed to maintain transport of pebble that is 1 centimeter in diameter?
50
Is six miles per hour per second north an example of velocity?
We're not completely sure what you mean by "per hour per second". Going just by what we see in the question, it's an acceleration, not a velocity. "Six miles per hour north" would be a velocity.
What is a change in velocity in given period of time?
Change in velocity = Velocity at the end of the period minus velocity at the start of the period.
How many 0.5 tiles are needed to completely cover a 4 foot wall?
Assuming it's a 4x4 wall, 64 tiles
When average velocity and average speed is equal?
For the instantaneous value of average velocity, average speed and average velocity are equal.
Does NOT describe a change in velocity?
Strawberry flavour certainly does not describe a change in velocity!
What must you have in a problem to adequately describe velocity?
Describe three situations in which a force changes the velocity of an object?
What may happen to a rocket which rises from the earth never attains escape velocity?
A rocket that doesn't reach "escape velocity" will be overcome by gravity and will be pulled back down to Earth. Also, rockets which go into orbit have not reached escape velocity. Escape velocity is what is needed to completely leave earth's gravity well.
What is a word to describe velocity?
speed
What is necessary to accurately and completely describe the motion of an object?
To completely describe the motion of an object you will need to know (1) the object's position in space and time, (2) the objects velocity, including the direction of travel, and (3) the object's acceleration, including the direction of acceleration. However, the Heisenburg Uncertainty principle states that the more accurately you measure object's position, the less information you will have about its velocity, and vica versa. The more accurately you measure an object's velocity, the less information you will have about its position.
What describes velocity?
two things that describe velocity is distance and time.
How do you describe acceleration in physical science?
it has velocity
What does acceleration describe?
Rate of change in velocity.
Does mph describe speed or velocity?
by itself it is speed; if associated with a direction it is velocity
How two things do you need to know to describe the velocity of an object?
Velocity includes speed and direction.
Which describe how velocity Change with time?
average speed.
Describe the to ways in which velocity can change?
speed and direction
