Answer:
Proton
Explanation:
Proton is a subatomic particle and determines the identity of an element. each element is identified by its atomic number. In an element, the number of protons in the nuclei of the atoms of the element is same as the atomic number of that element and this number is different for each element. for example, Boron has 5 protons in its nuclei, hence the atomic number of the element is 5.
Lucite has a refractive index of n=1.50. This means that the speed of the light in lucite is decreased according to:
where
is the speed of light in air. Putting the number in the formula, we find that the speed of light in lucite is
The frequency of the light is
, so now we can calculate the wavelength in lucite by using the formula:
<span>Therefore, the correct answer is (2) 393 nm.</span>
Answer:
<em>Answer A. Fission, steam, turbine, electricity, cool water</em>
Explanation:
<u>Nuclear Energy Production
</u>
Nuclear energy is produced by splitting uranium atoms in a process called fission. This generates heat and it's managed to produce steam, which later is used by a turbine generator to generate electricity. The heat must be taken out of the system, so a cooling process, usually involving water is the final step.
Because nuclear power plants don't burn fuel, they are known as clean energy sources.
Answer A. Fission, steam, turbine, electricity, cool water

<span>When temperature is increased,
the rate of dissolving increases. The kinetic energy of the molecules of the
solute and solvent molecules is high thereby increasing their contact. An example
is mixing powdered sugar to the water. When you add water to the sugar, the
dissolving process is slow. However, when you increase the temperature of the
water by boiling it, the sugar dissolves immediately. </span>
