Which of these is true of a person walking up the steps of a downward-moving escalator a a constant speed?
Here are some things that are true:* The combined speed is also constant * To get the combined speed, you need to subtract one speed from the other (the speed of the escalator, and the speed of the person relative to the escalator) * Acceleration is zero
What is true of a person walking up the steps of a downward moving escalator at a constant speed?
the person is decreasing resultant velocity
Which of these is true of a person walking up the steps of a downward-moving escalator at a constant speed?
There are many things that could possibly be true of a person walking up the steps of a downward-moving escalator at a constant speed. This person could potentially stay in exactly the same place.
What happens when speed increases?
when speed increases, velocity changes.
When the speed of particles in a gas increases what els increases?
As the speed of the particles in gas increases the heat of gas increases as well.
What does the lifting force on an airplane wing do?
increases with speed
How is the induced voltage of separately excited dc generator affected if the speed increases?
as speed increases, induced voltage increases
What happens to a graph of time and distance as speed increases?
The graph of distance vs time increases exponentially as speed increases.
Does the speed of a wave increases as a wavelength increase?
the frequenzy increases, the speed of light is constant
What happens to the speed of sound if the temperature of the medium increases?
Speed of sound increase when temperature increases.
Why the mass of the person increases in space ship?
Mass does not increase in a spaceship. Mass increases infinitesimally according to the speed of the body. This increase does not have any effect until light speed is closely approached. Which is presently impossible with our present technology.
Does wave speed increase as gravity increases?
yes,wave speed will increase as gravity increases.
