If a person is walking up the steps of a downward moving escalator at a constant speed, they will feel as if they are walking on a stationary surface. The person's upward motion will cancel out the downward motion of the escalator, resulting in no net movement relative to the escalator itself.

Which of these is true of a person walking up the steps of a downward-moving escalator at a constant speed?

If a person is walking up the steps of a downward-moving escalator at a constant speed, then their speed relative to the ground will be the sum of their walking speed and the speed of the escalator. This means they will ascend the steps slower compared to if the escalator was stationary or moving upwards.


Which of thesse is true of a person walking up the steps of a downward moving escalater at a constant speed?

The person is walking faster than the escalator is moving downward in order to reach constant speed.


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 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 down ward moving escalator at a constant speed?

If a person walks up the steps of a downward moving escalator at a constant speed, they will be able to ascend the escalator slower than if it were stationary. Their relative speed to the escalator will be decreased, allowing them to maintain a steady pace upwards.


How does the escalator help us?

The escalator moves so that either people can relax from walking and just stand there or they can walk but faster.

A shopping bag is hanging straight down from your hand as you walk across a horizontal floor at a constant velocity does this force do any work while you are riding up an escalator at constant velocit?

While you are walking across a horizontal floor at a constant velocity, the force your hand exerts on the bag does no work. However, when you ascend an escalator, the force does perform work on the bag. Why? To do work is to change the energy of an object. In this case we have either kinetic energy, or gravitational potential energy. The first case we are walking on a horizontal floor, there is no change in height, thus no change in potential energy. We are also moving at a constant speed, thus no change in kinetic energy. If we sped up, or slowed down, then we would do work. In the second case, we are ascending an escelator, and changing the height. This changes the gravitational potential energy, and thus does work.


Why is equilibrium said to be dynamic in a closed system?

The system is in "equilibrium" because the rates of the reactions (or in this case simply changes of state) in both directions are equal, and the amounts of liquid and vapour are constant. The "dynamic" part describes the fact that the reactions/changes of state are indeed happening even though no change is observed from the outside. It's like walking up an escalator which is moving downwards - to someone watching it doesn't look like you're moving, but in fact you are working to stay in the same place.
