Two long, straight, parallel wires separated by a distance of 20 cm carry currents of 30 a and 40 a in opposite directions. what is the magnitude of the resulting magnetic field at a point that is 15 cm from the wire carrying the 30-a current and 25 cm from the other wire?
Answers: 2
=30 A
40 A

Will give brainliest! which statement best describes the similarities between fundamental forces? electromagnetic and strong nuclear forces influence the interaction between charged particles within an atom. gravitational and magnetic forces are both types of charges that occur in nature. nuclear and magnetic forces are both related to mass and weight. strong nuclear force is most like electrical force because they are both related to distance.

This is a form of winter precipitation. it is frozen precipitation falling as ice pellets. snowflakes melt into raindrops as they pass through a thin layer of warmer air. the raindrops then refreeze into particles of ice when they fall into a layer of sub-freezing air near the surface of the earth. this precipitation is called a) hail. b) rain. c) sleet. d) snow.
