Answer:
How high the plants grow in the different soils.
Explanation:
The dependent variable is what happens as a result of what the experimenter changes.
The experimenter could measure how high the plants grow when placed in soil with different pH values.
I think the correct answer from the choices listed above is the first option. The best example that demonstrates the relationship between temperature and pressure would be that <span>bubbles forming in dough when it is heated. Hope this answers the question.</span>
This is commonly true, but not always.
V = f 入 (velocity = frequency x wavelength)
<span>If we have the speed ( for wave in vacuum </span><span>i.e. 3 x 10^8 m/s) </span>
<span>Then the frequency of x-ray is </span>
<span>(3 x 10^8) ÷(1.15 x 10^-10) = 2.61 x 10^18 </span>
Answer:
15.37 atm
Explanation:
According to Dalton's law of partial pressure, the total pressure of a mixture of gases in the tank is a sum of the individual pressures of all the gases. Hence;
PT = P1 + P2 + P3 -----------
So;
Ptotal = Phelium + Poxygen
Poxygen = 4.63 atm
Ptotal = 20.0 atm
Phelium = 20.0 atm - 4.63 atm
Phelium = 15.37 atm
