Answer:
1 gallon = 3.8 liters rounded to the nearest tenth.
Explanation:
1 gallon = 3.785 litres.
We have to round this in to nearest tenths, nearest tenth means number of figures after decimal = 1.
Here last digit is 5 so we have to add 1 to previous digit.
So, 3.785 rounded will become 3.79
For 3.79 the last digit is 9 so we have to add 1 to previous digit.
So, 3.79 rounded will become 3.8
3.785 liters rounded to the nearest tenth is 3.8 liters.
1 gallon = 3.8 liters rounded to the nearest tenth.
Explanation:
It is known that formula for energy in the 1st exited state is as follows.
E =
And, for 1st exited state n = 2.
So, E =
= -3.4eV
It is given that energy added E' = 2.86 eV.
So, energy of the electron in nth state is as follows.
E" = E + E'
= -0.54 eV
we know E" =
-0.54 eV =
n' = 5
i.e., the electron exited from n = 1 to n = 5.
Thus, we can conclude that the quantum number n of the state into which the electron moves is from n = 1 to n = 5.
Answer: if the mass is doubled, the force of gravity is doubled, meaning it decreases. If the distance is doubled, the force of gravity is 1/4 as strong as before
Explanation:
I'm guessing <span>10.6% based on the following information:
</span>
Mass soln = <span>density×volume=1.06×875=927.5<span>g
</span></span><span><span>M<span>NaCl/</span></span><span>Msoln</span></span>×100=<span>%M
which means this:
</span>
%M=98.6927.5×100=10.6
