A sinusoidal, transverse wave that propagates in the positive x-direction can be described with the wave function y of xt is equal to A times cosine of start parenthesis k times x minus omega times t end parenthesis, where k is the wave number, x is the position of a point on the wave, omega is the angular frequency, and t is time. What is another way to express the angular frequency, omega

rad/s

Explanation:

The wave function is:

where :

k = wave number

x = position of a point on the wave

= angular frequency

t = time

What is another way to express the angular frequency (omega)

Angular frequency (omega) can be express as :

rad/s ( i.e one repetition that it takes to repeats itself)

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
