Study the vector diagram. Three vectors are drawn tail to tip method in the x y plane. Vector labeled T starts at the origin and is drawn in the northeast direction. The second vector is labeled U and drawn in the south south east direction. The third is labeled V and drawn in the north northeast direction. X and Y components are drawn for each vector along the x and y axis.

Which formula can be used to find the x-component of the resultant vector?

Tx - Ux - Vx
Tx + Ux + Vx
Tx = Tcosθ
Tx = Tsinθ

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.

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
