Chemistry

The frequency of a wave, represented by the letter f, is the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency. The SI unit of cycles per second is called hertz or Hz. Hz can be expressed as a reciprocal second (s-1 or 1/s).

The number of waves that pass a point in 1 second

Pressure is caused by collisions of gas molecules with surfaces or other gas molecules.

It is a universal constant used for all gases.

To utilize the wing space for the fuel,

Changing the temperature will change Keq. (apex.)

they often form hydroxide ions

The wright brothers figured out how to outfit the plane with wings that flapped, similar to birds' wings. - Apex- Chemistry Semester 2.

More drag is created because the molecules cannot "hear" the airplane coming.

The Le Chtelier's principle states one thing. It is the dynamic equilibrium which is disturbed by changing the conditions and the position of equilibrium moves that makes a change.

The airplane may succumb to the power of gravity as lift decreases at higher altitudes.

When pilots get closer to the speed of sound it gets harder for the plane to fly. It could also depend on the how the pilot flees.

This is called molality.

Kc is the equilibrium constant of a chemical reaction; Kp is the equilibrium constant of a chemical reaction at constant pressure.

This causes alot of heat that the airplane must be shielded from

Generates more lifting force

Drag

Friction

Lift

design extra reinforcements in the buildings windows so that they can withstand the vibrations from sonic booms

Begin to succumb to the power of gravity because of the decrease in lift

released through the back of the engine to propel it and the airplane foward

sodium hydroxide

The answer is "Ions in water" on Apex
