Answer:
a) uranium
b) deuterium
Explanation:
For the first question, you can actually know this by simple logic. The nucleus of Ucranium, has more energy than a pair of deuterium. Ucranium has a mass number and atomic mass higher than deuterium, therefore, when you do a fission with ucranium in it's nucleous, this would be in energy higher than the deuterium.
However, in terms of mass only, the fissioning of 1 gram of Deuterium will produce more energy than 1 gram of uranium, basically because deuterium is lighter and has a lower molecular weight than ucranium. This means that because of this lower molecular weight, in 1 gram of deuterium will contain more number of atoms than in 1 g of uranium. The interaction with these atoms, will produce more energy than the energy produced by uranium.
Correct answer choice is :
B) They are also called longitudinal waves.
Explanation:
S-waves, secondary waves, or shear waves are a kind of flexible wave also are one of the two principal kinds of elastic body waves, so called because they travel through the body of an object, unlike surface waves. It pushes and pulls the rock it travels through just like sound waves push and pull the air. The second kind of body wave is the S wave or secondary wave, which is the next wave you feel in an earthquake. An S wave is delayed than a P wave and can only move through solid rock, not through any fluid medium.
