Answer:
The density of the swimmer is 0.0342 lbm/in3.
This value makes sense as the density of the body is very similar to the water.
Explanation:
If the swimmers is floating, the weight of the swimmer must be equal to the upward buoyant force.
We can express the weight force as the product of density and volume of the swimmer.
Then
![\rho_{swimmer}*V_{swimmer}=\rho_{water}*V_{water_displaced}\\\\\rho_{swimmer}*V_{swimmer}=\rho_{water}*0.95**V_{swimmer}\\\\\rho_{swimmer}=0.95*\rho_{water}\\\\\rho_{swimmer}=0.95*0.036 lbm/in3\\\\\rho_{swimmer}=0.0342lbm/in3](https://tex.z-dn.net/?f=%5Crho_%7Bswimmer%7D%2AV_%7Bswimmer%7D%3D%5Crho_%7Bwater%7D%2AV_%7Bwater_displaced%7D%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3E%5Crho_%7Bswimmer%7D%2AV_%7Bswimmer%7D%3D%5Crho_%7Bwater%7D%2A0.95%2A%2AV_%7Bswimmer%7D%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3E%5Crho_%7Bswimmer%7D%3D0.95%2A%5Crho_%7Bwater%7D%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3E%5Crho_%7Bswimmer%7D%3D0.95%2A0.036%20lbm%2Fin3%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3E%5Crho_%7Bswimmer%7D%3D0.0342lbm%2Fin3)
It makes sense as the density of the body is very similar to the water.
Answer:
+2
Explanation:
Since O &F Are more electronegative than N,
F=-1
2F=-2
O=-2
also the compound is neutral,
then 2N+2F+O=0
2N-2-2=0
2N=+4
N=+2
For a and b, you need to divide it by Avogadro’s number to find the answer.
a. (6.022x10^23)/6.022x10^23 = 1 mole of Ne
b. (3.011x10^23)/6.022x10^23 = 0.5 moles of Mg
For c and d, you’ll use the mass provided divided by the molar mass to find the number of moles.
Pb molar mass = 207.2 g/mol
c. (3.25x10^5)/207.2 = 1.57x10^3 moles of Pb
For d, I can’t tell if is Cu, C or something else but you can follow the steps above to solve the problem.
They are different and unique from the other statea of matter.
plasma is different from a gas, because it is made up of groups of positively and nagatively charged particles. In neon gas, the electrons are all bound to the nucleus
Lactic and alcholic happens when there is no oxygen.
So, how did it happen?
Recall that in glycolysis of cellular respiration, there is a glucose (6 Carbons) molecule. That glucose molecule is going to be broken down into two pyruvates (3 Carbons). There is no oxygen (also know as anaerobic respiration) so pyruvate is going to be converted into lactate or alcoholic fermentation depending on it's accessibility.
