Answer:
elements in the elements now are different end of story
Answer:
a). m/s
b). 1.23 m/s
Explanation:
Given :
Index of refraction for water, = 1.33
Index of refraction of diamond, = 2.42
We know that,
Refractive index of any material is given by,
where c = sped of light in air
v = speed of light in any medium
a). Speed of light in water
m/s
b). Speed of light in diamond
= 1.23 m/s
answer=H+]=10-7
explain=the same way, a solution with a pH of 5 contains 10-5mol/l of hydrogen ions, a solution with a pH of 6 contains 10-6mol/l of hydrogen ions, while the solution with a pH of 7 contains 10-7mol/l of hydrogen ions
The answer to the question is D
