The nuclear binding energy of one nitrogen-14 atom is (BLANK) x 10A J. Round to 3

d1i1m1o1n [39]

mass defect = mass of constituents - mass of atom

N has 7p and 9n

proton mass ~ 1.00728 amu

neutron mass ~ 1.00866 amu

electron mass ~ 0.000549 amu

Nitrogen mass ~ 14.003074 amu

mass defect = (7*1.00728)-(7*1.00866)-(7*0.000549) - 14.003074

= 0.11235amu

convert to energy, the binding energy = 1.68x10^-11 J

alexdok [17]

Answer:

Explanation:

Satellite acts as a relay station for earth sources. A transmission station sends the information to the satellite, which in turn retransmits to the receiving stations. The original signal being transmitted from the earth station to the satellite is called uplink of 6 GHz The retransmitted signal from the satellite to the receiving station is called downlink of 4 GH frequency. The transponder is the transmitter-receiver combination in a transponder.
