Consider a conducting sphere with a radius as of 1 m. what is the rcs of this sphere at an rf of 10 ghz? give the answer in units of both square meters and dbsm. (assume the sphere is "much larger than" the wavelength.) what must be the side length at of a trihedral so that it has the same rcs at 10 ghz? what is the ratio of the size of the sphere compared with that of the trihedral, as/at ?

Aloop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. a loop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. moving the loop outside of the magnetic field region. spin the loop such that its axis does not consistently line up with the magnetic field direction. change the magnitude of the magnetic field. change the diameter of the loop
