Answer:
Diamond
Explanation:
As light moves from a less dense medium to a denser medium it slows down.
This is because the wave length of the light reduces. The denser the medium the less the wavelength. Diamond is the most dense solid among the provided choices thus light travelling through it has the least wavelength.
Answer: 5.48
Explanation:
pH is the negative logarithm of hydrogen ion concentration in a solution.
Mathematically, pH = - log(H+)
where H+ represent the concentration of hydrogen ion
So, to get the pH of the solution with [H +] = 3.25×10-6 M:
Apply, pH = -log(H+)
pH = - log (3.25×10-6 M)
pH = - ( -5.48)
(Note that the minus signs will cancel out each other)
Therefore pH = 5.48
Now we know that the pH of the solution with hydrogen ion concentration of 3.25×10-6 M is 5.48 (i.e slightly acidic)
Thus, we can finally say 5.48 is the pH of the solution within a solution with pH = 4.50
Answer:
In a long channel MOSFET, the width of the pinch-off region is assumed small relative to the length of the channel. Thus, neither the length nor the voltage across the inversion layer change beyond the pinch-off, resulting in a drain current independent of drain bias. Consequently, the drain current saturates.

The answer can be explained when you burn something cleanly (with a very hot item) or not. With a candle lots of Carbon dioxide is producted but when using a bunson burner hardly any CO2 is produced.
Answer:
answer is 2.04*10^4 kPa
Explanation:
Dalton's Law of Partial Pressures.
it is because that when the volume and the temperature of a gaseous mixture are kept constant, the total pressure of the mixture is equal to the sum of the partial pressures of its gaseous components .
