QUESTION 1In the process of nuclear fusion,
a. two or more nuclei fuse or stick together to form a heavier nucleus whose combined mass is slightly greater than the original nucleus
b. two or more nuclei fuse or stick together to form a heavier nucleus whose combined mass is slightly less than the original nucleus
c. a heavy nucleus breaks apart into a number of smaller nuclei whose combined mass is less than the original nucleus
d. two or more nuclei fuse or stick together to form a heavier nucleus that has exactly the same mass as the original nucleus
QUESTION 2 In our solar system, Jovian planets are
a. large, made mostly of gases and liquids with low densities, and found far from the Sun
b. large, made of pure gases with low densities, and found far from the Sun
c. small, made of pure rock with high densities, and found close to the Sun
d. small, made mostly of rock and iron with high densities, and found close to the Sun
Explanation / Answer
Second option is correct that is nucleus fusion is the process in which two nuclei fuse or stick together to from a heavier nucleus whose combined mass is slightly less than the original nucleus because the loss of mass is used to produce the energy. And hence option “b” is correct. Jovian planets are composed of gases as well as ice and they also have gas so condensed that they become liquid and they are present far from the sun and hence option “a” is correct.
