Three point charges are arranged in an equilateral triangle. the bottom left charge is located at the origin (0.000 m, 0.000 m) and has a charge of +3.00 µc, the bottom right charge is 20.0 cm away at (0.200 m, 0.000 m) and has a charge of −2.00 µc, and the top charge is located at (0.100 m, 0.173 m) and has a charge of +4.00 µc. find the electric field vector (magnitude and direction! ) at the origin, and then use it to calculate the force on the +3.00 µc charge located there.'

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50

asthenosphere and convection

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
