Answer:Stirring.
Explanation:Stirring a solute into a solvent speeds up the rate of dissolving because it helps distribute the solute particles throughout the solvent. For example, when you add sugar to iced tea and then stir the tea, the sugar will dissolve faster.
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
Answer:
(177.94 ± 3.81) cm^2
Explanation:
l + Δl = 21.7 ± 0.2 cm
b + Δb = 8.2 ± 0.1 cm
Area, A = l x b = 21.7 x 8.2 = 177.94 cm^2
Now use error propagation
So, the area with the error limits is written as
A + ΔA = (177.94 ± 3.81) cm^2
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.
For convenience write RC=D and solve the ODE dV/dt=-V/D which gives
<span>V=Ae^(-t/D) by separating the variables. </span>
<span>When t=0, V=10 and this gives A=10, </span>
<span>when t=2, V=1 giving 1=10e^(-2/D) and you can find D by taking lns of </span>
<span>each side. D=RC, so R=D/C </span>
<span>You should get 2.90X10^5 ohms</span>
