const2013 [10]

The final speed of C is equal to that of B.

The travel time of A is less than that of B.

The final speed of B is equal to that of A.

The travel time of C is greater than that of B.

The final speed of A is equal to that of C.

The travel time of C is greater than that of A.

<h3>What is speed?</h3>

The speed of any moving object is the ratio of the distance covered and the time taken to cover that distance.

Consider the three inclines shown in the figure (attached below). The vertical line is an incline with a 90° angle. All three inclines are frictionless. Three small identical objects are released from the top of the inclines.

When the objects are at the same height, they travel with the same height. The travel time is directly proportional to the incline.

Thus, all the statements are completed.

How is the reaction quotient used to determine whether a system is at equilibrium?
Juli2301 [7.4K]

Answer:

The answer to the question above is explained below

Explanation:

The reaction quotient, Q, is a measure of the relative amounts of reactants and products during a chemical reaction as it can be used to determine in which direction a reaction will proceed at a given point in time. Equilibrium constant is the numerical value of reaction quotient at the end of the reaction, when equilibrium is reached.

If Q = K then the system is already at equilibrium. If Q < Keq, the reaction will move toward the products to reach equilibrium. If Q > Keq, the reaction will move toward the reactants in order to reach equilibrium. Therefore, by comparing Q and K, we can determine the direction of a reaction.

Where Q= reaction quotient and Keq= equilibrium constant for the reaction.

The larger the equilibrium constant, the further the equilibrium lies toward the products. Reaction quotient is a quantity that changes as a reaction system approaches equilibrium.  

We can determine the equilibrium constant  based on equilibrium concentrations. K is the constant of a certain reaction when it is in equilibrium. Equilibrium occurs when there is a constant ratio between the concentration of the reactants and the products.

Which determines the pitch of a sound? A. At the same wavelength, the sound with the most cycles per second will have the highes
kipiarov [429]
This would be known to be determined by its sound wave which would be the amplitude. The pitch of sound would actually be a little differenr in this matter. But know that we know and understand the sound wave of the pitch of sound, we know that this is done by amplitude.

One way to produce a beam of polarized light with intensity I and polarization angle θ would be to pass unpolarized light with i
Karo-lina-s [1.5K]

Polarization of light is achieved by passing the light through a polarizer which causes the light to vibrate in only one direction.

<h3>What is  polarization of light?</h3>

The question is unclear but I will try  to explain what is meant by polarization of light.  We know that light is an electromagetic wave and vibrates in all directions.

The polarization of light enables light to vibrate in a specified direction. This is achieved by passing the light through a polarizer which causes the light to vibrate in only one direction.
