Answer:
Uranium
Explanation:
The nuclear power plants on Earth work based on the principle of nuclear fission.
Nuclear fission occurs when a heavy unstable nucleus splits into lighter nuclei: in this process, the total mass of the final product is smaller than the mass of the initial heavy nucleus, so part of the mass is converted into energy according to Einstein's equation:

where E is the energy released when an amount of mass m is converted (c is the speed of light).
Generally, the "fuel" (the initial heavy unstable element) used in nuclear power plants is uranium. A nucleus of uranium is bombarded with slow neutrons, which cause the process of nuclear fission to start: the nucleus of uranium split into lighter nuclei, releasing also additional neutrons, which are used to start further nuclear reactions.
Answer:
Every summer we go and work at a summer camp. My whole family loves it, and it's something that always brings us closer.
Explanation:
<h3><u>Answer;</u></h3>
Each will reflect at an angle equal to its angle of incidence.
<h3><u>Explanation;</u></h3>
- <em><u>When light hits a surface or a boundary it bounces of the surface a phenomenon called reflection, which is a property of waves. Reflection occurs such that the incidence angle is equal to the angle of reflection.</u></em>
- Reflection of light depends on whether the surface is smooth or rough. When the light hits a smooth surface it bounces off the surface and all the rays of light moves in the same direction, this type of reflection is called specular reflection.
- On the other hand , when right rays hits a rough surface the rays bounces off the surface and the rays move in different directions, a type of reflection called diffuse reflection.
Here we will the speed of seagull which is v = 9 m/s
this is the speed of seagull when there is no effect of wind on it
now in part a)
if effect of wind is in opposite direction then it travels 6 km in 20 min
so the average speed is given by the ratio of total distance and total time


now since effect of wind is in opposite direction then we can say



Part b)
now if bird travels in the same direction of wind then we will have


now we can find the time to go back



Part c)
Total time of round trip when wind is present


now when there is no wind total time is given by


So due to wind time will be more
