Project seafarer was an ambitious program to construct an enormous antenna, buried underground on a site about 1 km^2 in area. its purpose was to transmit signals to submarines while they were deeply submerged. ordinarily, electromagnetic radiations do not penetrate very far into conductors such as seawater. assume that the effective wavelength was 3.5 x 10^4 earth radii.
(a) what would be the frequency of the radiations emitted? (units in hz)
(b) what would be the period of the radiations emitted? (units in seconds)

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
