Answer:
C. Water passes into the salt solution, dehydrating bacterial cells and making them harmless.
Explanation:
The salt solution is hypertonic to the bacterial cells and as such, water molecules will move from the bacterial cells into the salt solution, dehydrating the cells and rendering them harmless.
Option A is also true but it is irrelevant to the question asked. Option B and D are wrong.
The correct option is C.
Answer:
0.4590
Explanation:
How the refractive index of the hexane + toluene mixture varies linearly with mole fraction, it means that the mole fraction is the fraction that each pure index contribute for the mixture index, so, calling <em>xh</em> the mole fraction of hexane and <em>xt</em> the mole fraction of toluene:
1.375xh + 1.497xt = 1.441
And, xh + xt = 1 (because there are only hexane and toluene in the mixture), so xt = 1- xh
1.375xh + 1.497(1-xh) = 1.441
1.375xh + 1.497 - 1.497xh = 1.441
-0.122xh = -0.056
xh = -0.056/(-0.122)
xh = 0.4590
Transverse wave:
⇨- the way the wave is moving
⟶- Medium - the material it is traveling through
冖- Wavelength - the distance from crest to crest
C - Crest - the highest point on a wave
T - trough - the lowest part on a wave
↕️ - Amplitude - the distance from rest to crest
ྊ - (tinfoil)Wave
Description:
In the beginning of the wave the wavelength is short and the frequency is high so is the energy.and the amplitude is low *i believe* And after the mark of T shown on the image the wavelength is long and the frequency is low and so is the energy and the amplitude is high *i believe*.Amplitude and wavelength are both measures of distance.
Longitudinal/Compressional Wave:
KEYS:
⟶-medium - the material it is traveling through
⇨-way the wave is moving
冖-wavelength - the distance from crest to crest
R -Rarefaction - the opposite of compression
C-Compression - particles are closest together
Here, Hydrogen is having the positive ion is placed at the first and oxygen is having negative ion is placed at the second position. Here, Hydrogen is having the positive ion is placed at the first and oxygen is having negative ion is placed at the second position. Therefore, it is written as H2O and not HO2.
