A toy boat that is 0.10 m long is used to model the actions of an actual boat that is 30 m long. Which ratio shows the relationship between the sizes of the
model and the actual boat?
O A. 1:3
B. 300:1
O C. 1:300
D. 3:1

Explanation:

Size ratio of actual to model = 30 : 0.10 = 300 : 1. (B)

C.  1:300

Explanation:

given:

A toy boat that is 0.10 m long is used to model the actions of an actual boat

that is 30 m long

find:

which ratio shows the relationship between the sizes of the

model and the actual boat?

model = 0.10 m

actual = 30 m

30 / 0.1 = 300

therefore,

the scale ratio of model to actual = 1:300

C.  1:300

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

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
