What is the average binding energy per nucleon for a u-238 nucleus with a mass defect of 0.184 amu? (1 amu= 1.66 x 10-27 kg; 1 j = 1 kg m2/s2) 2.38 x 10-30 j 2.75 x 10-11 j 1.01 x 10-20 j 1.16 x 10-13 j

add all the number and find the average then subtract the mass defect and then you will get your answer

thats how its supposed to be

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
