Two long, parallel wires are separated by 2.8 m . each wire has a 30-a current, but the currents are in opposite directions. a. determine the magnitude of the net magnetic field midway between the wires. express your answer to two significant figures and include the appropriate units. b. determine the magnitude of the net magnetic field at a point 1.1 m to the side of one wire and 3.3 mfrom the other wire. the point is in the same plane as the wires. express your answer to two significant figures and include the appropriate units.

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m
