In an amusement park ride a girl stands with her back against the inside wall of a circular room The room begins to whirl around After the room reaches a constant speed the floor drops down?

If your wondering why the girl doesn't fall, it's due to gravity and G-force. Basically, since the room is spinning so fast, it produces G-force, which if strong enough will pin the girl to the wall and keep her there, not falling. G-force is also felt on rollercoasters, waltzers and also the space shuttle when it takes off. It's the force that causes resistance when you try and stick your arms out in front of you or lean forward on a rollercoaster.

The reaction shown below reaches equilibrium with the concentrations CO2 equals 0.15 CO equals 0.03 O2 equals 0.05 What is the equilibrium constant for this reaction?
H2(g) + I2(g) 2HI(g)18.6
Can you accelerate and keep the same speed?
Acceleration means any change in either speed or direction of motion.If speed remains constant, there may still be acceleration present if thedirection of the motion is changing.If the rate at which speed and/or direction are changing remains constant,then the acceleration is constant
As water is cooled its density does what until it reaches about 4 C?
As water is cooled its density increases until it reaches about 4 C and then it decreases.
What does force applied to a stationary object give the object?
Newton's First Law of Motion states that objects will remain in their current state of motion (whether stationary or travelling at a constant velocity) unless an outside force acts on them. If he force you are mentioning here causes the net force to become unbalanced, then the force will cause the object to accelerate until the forces are balanced and it reaches either a constant speed, or the opposing force causes it to decelerate and eventually become stationary.
When an air bubble rises in water what happens to its potential energy?
no matter what happens to the bubble, even if it sinks or rises, the mass will remain the same throughout. we all know that as we go deeper into water, the pressure increases with the depth. hence, when the bubble rises, the pressure exerted on it decreases and simultaneously, the volume increases. that is all that happens to the bubble. the mass remains constant unless it bursts. the mass of air in the bubble originally is now dissolved in the water. always remember that the mass of anything is constant as long as it is acted upon the same gravitational force.
What is ion product constant?
Ion product constant is essentially when something reaches equilibrium. Such as in the case of water. When water reaches its ion product constant it becomes both a base and an acid, reaching equilibrium.
When does a planet move fast or slow?
A planet in an elliptical (oval) orbit will move faster as it gets to its closest point to its sun, and slow down as it reaches its furthest point. A planet with a truly circular orbit will have a constant speed.
What happens to the forces of an object when it reaches a constant speed?
An object maintains a constant velocity when the net force acting upon that object is zero. Therefore, a force pushing against the object that exactly opposes the force(s) due to friction (in both magnitude and direction) will result in a net force of zero, and the object will maintain a constant speed.
Does tea cool at a constant rate?
Yes, assuming that the environment in which the tea is "living" stays a constant temperature. Tea will cool at a constant rate, until it reaches the temperature of the environment (but it will not get any colder than this).
What happens to covection currents when a fluid reaches a constant temperature?
As the fluid warms:The currents speed upThen as the temperatures of the fluid equalise (the fluid becomes one temp) the currents slow downWhen the fluid is one temperature the currents stop
What happens when an object reaches terminal velocity?
It stops accelerating, and falls the rest of the way at constant speed.
When A parachutist reaches it terminal speed?
The parachutist will no longer accelerate. They will just glide with constant velocity and enjoy the scenery.
When water is heated the temperature eventually reaches a constant value and forms a plateau on the graph what does the plateau indicate?
The boiling point.
What typically happens to the amount of entropy?
It increases. Once it reaches its maximum value, it remains constant. This is not just "typical", it is unavoidable.
What is the difference between linear and circular queue?
What is the difference between linear and circular queue? In: http://wiki.answers.com/Q/FAQ/2545-37 [Edit categories]The Queue by Default is Linear, it would be termed as Circular if the Last Element of the Queue pointsto the first element of the List
What is terminal motion?
the constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration.
How do you find whether linked list is circular or not?
To determine if a linked list is circular, you can use the Floyd's cycle detection algorithm. This algorithm involves using two pointers moving at different speeds through the list, and if there is a cycle, the two pointers will eventually meet at the same node. If they don't meet and one of the pointers reaches the end of the list, then the list is not circular.
