The electric field radiated at large distances in free space by a current-carrying small circular loop of radius a, placed on the xy plane at z 0, is given by cos (t r) for r » a , where eo is a constant, β○ wvaoeo, r is the radial dis- tance in spherical coordinates, and θ is the spherical angle measured from the z axis that is perpendicular to the plane of the loop. de termine the corresponding radiated magnetic field at large distances from the loop (r» a).

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!

it would be c. predictability

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
