Three forces in a plane act on an object. A force of 25 pounds is exerted 70° above the positive x-axis. The second force is 50 pounds is exerted above the x-axis, such that the angle between the force
and the 25-pound force is 65º. The final force of 43 pounds is applied below the x-axis at a 30° angle with the
axis.
Draw a diagram, and then find both the magnitude and direction of the resultant force. Round all decimals to
the nearest hundredth, when necessary.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

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
