Although the evidence is weak, there has been concern in recent years over possible health effects from the magnetic fields generated by transmission lines. a typical high-voltage transmission line is 20 m off the ground and carries a current of 200 a . part a estimate the magnetic field strength on the ground underneath such a line. express your answer in microtesla. b b = nothing μt submitrequest answer part b what percentage of the earth’s magnetic field does this represent? (assume that magnetic field strength at the surface of the earth is 5× 10 −5 t ) express your answer in percent. b tl b earth b t l b e a r t h = nothing % submitrequest answer provide feedback next

Will give brainliest! which statement best describes the difference between strong nuclear forces and weak nuclear forces? weak nuclear forces are involved when certain types of atoms break down. strong nuclear forces are responsible for holding atoms' nucleus together. weak nuclear forces hold bonds between atoms together. strong nuclear forces hold together the nucleus of an atom. strong nuclear bonds prevent atoms from falling apart. weak nuclear bonds prevent compounds from falling apart. strong nuclear forces are involved in breaking electrons from their shells. weak nuclear forces hold protons in the nucleus.
