Answer:
6.4 kilometers per hour
Explanation:
Just do the amount of distance she covers divided by how many hours she rides to get the answer. In this case, its 25.6 divided by 4 which equals 6.4
Answer:
there are conversion scales used for doing that
to convert Celsius to Fahrenheit we use the formula,
T(°F) = T(°C) × 9/5 + 32
and to convert Fahrenheit to Celsius we use,
T(°F) = T(°C) × 5/9 + 32

Answer:
2000 kg/m³
Explanation:
Density = (mass[kg])/(volume[m³])
Density of the brick = (.128kg)/(.02•.04•.08) = 2000 kg/m³
An electron shell can hold 2(n^2) electrons (technically) where n is the shell number, i.e. shell 1 can hold 2, shell 2 can hold 8, 3 holds 18 and so on.
The atomic number of Nitrogen is 7, i.e. it has 7 electrons (to match its 7 protons, assuming it isn't an ion).
With the atomic number, you simply start from shell 1 and work out. So we put 2 electrons in shell 1, leaving us with 5 left. Shell 2 can hold 6 so we can fit all 5 in.
In other words, you should have 2 electron shells on the atom, shell 1 with 2 e- and shell 2 with 5 e-.
<span>Nuclear energy is cleaner while generating electricity. Nuclear fission provides energy without releasing greenhouse gases such as carbon dioxide. However, nuclear power plants generate significant amounts of radioactive waste. That is why we should not choose nuclear energy over fossil fuel power plants.</span>
