The formula for kinetic energy is
KE = (1/2) (mass) (speed)² .
How you measure the object's mass and speed is up to you.
You'd need different methods for different objects, and in some
cases, you'd need quite a bit of ingenuity.
Because it's placed in the lasagna, the thermal energy is transferred by conduction. Remember, convection is transfer of heat through fluids (liquids and gases), and radiation is just transfer of heat through air.
It must be a mixture, because the ingredients can be separated. You can precipitate sugar from water, there's no chemical reaction involved. I actually made lemonade pops once and the lemon juice and sugar comes out of solution as the water freezes.
Answer:
1. Nuclear fusion does not generate radioactive nuclear wastes as nuclear fission does.
2. Nuclear fusion cannot lead to disastrous powerplant explosions as nuclear fission does.
3. More energy is generated during nuclear fusion than in nuclear fission.
Explanation:
Nuclear fusion involves the combination of lighter atoms such as hydrogen to form a heavier nucleus, in the process producing a tremendous amount of energy.
Nuclear fission on the other hand involves splitting a heavy nucleus into two lighter nuclei, releasing energy in the process.
- Nuclear fusion can be more reliable than nuclear fission in energy generation due to the following reasons:
- There are no radioactive waste products obtained as a result of nuclear fusion, unlike nuclear fission. This is because the elements involved in Nuclear fusion are relatively radioactively stable elements.
- The risk of nuclear powerplant explosion due to out of control chain reactions is reduced in nuclear fusion because the reaction can only occur in perfect conditions under high pressure and temperatures <em>(e.g the sun)</em>. When any of these conditions is removed due to a fault, the reaction automatically stops.
- More energy is generated during nuclear fusion than in nuclear fission.
<span>So we wonder how can we compare yellow and orange light. Light is a small art of electromagnetic spectrum which is a continuum of all electromagnetic waves arranged by wavelenght and frequency. So on the EM spectrum orange has greaterr wavelangth than yellow but smaller frequency because wavelength and frequency are connected by the equation: c=f*lambda, where lambda is the wavelength and c is the speed of light and f is the frequency. We see that the higher the frequency the smaller the wavelength and vice versa.</span>
