Which of these events is an example of resonance? A- a bridge collapses due to the overloading of vehicles using it.
B-A baker kneads dough by pounding it repeatedly
C-The sound of teo guitars changes from loud to soft every second
D- An ambulance siren rises and falls in frequency as it passes by you
E-An opera singer breaks a thin glass with only the use of her high frequency voice

E- An opera singer breaks a thin glass with only the use of her high frequency voice

Explanation:

Resonance is when a person is able to evoke emotions or when a person is deep in character. It is the ability to evoke memories, images and emotions.

Examples of resonance include old pictures which has emotional attachments, feel voice of a singer etc.

Therefore, the event that is an example of resonance is an opera singer breaks a thin glass with only the use of her high frequency voice.

i think they are all correct

explanation:

they seem good

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
