Around loop of wire carries a current of 100 a, has a radius of 10 cm, and its normal (vector) makes an angle of 30∘ with a magnetic field of 0.524 t. 1) what is the torque on the loop? (express your answer to two significant figures.)

An electric current is flowing through the cord below. what will happen to this current if a magnet is brought near the cord? a. the electric current will stop flowing. b. it will exert a force on the voltage. c. the resistance of the wire will decrease. d. it will exert a force on the electric current.

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
