Answer:
Explanation:
We just have to calculate what angular displacement a ball with an average angular velocity of 290 rev/min experiments in 0.64s. By definition, angular velocity is the angular displacement divided by the time elapsed:
Since and , we can covert:
Where the terms between parenthesis are equal to 1, so they just change the units. Then for our values we have:

Answer;
- Nuclear fusion
Explanation;
-Hydrogen bombs and stars both produce energy with the nuclear fusion. On other side, the Sun and other stars make heat and light by nuclear reactions.
-The first stage of a hydrogen bomb involves a fission explosion which in turn leads to a nuclear fusion. The extreme heat and pressure from the initial atomic blast force together deuterium and tritium (two light gases made of hydrogen). When they are forced together, some of the hydrogen atoms fuse to one another, creating helium.
-This process of fusion releases even more energy per unit of mass than fission does, and the energy released from the fusion reaction also feeds back into the fission reaction, increasing its output.
