Answer:
Or in the other way:
Explanation:
For this case we need to remember that hectare is a measure of area. And we have the following ratios:
We can convert this into
We can convert this into
By dimensional analysis we assume that we can find the ratio in terms of distance like this:
And if we find the ratios in terms of distance we got:
Or in the other way:

I'm in middle school, but I think I know the answer, I am sorry if I am wrong.
It's D
Answer:
the kinetic energy decreases
Explanation:
When a liquid is cooled, the kinetic energy of the particles decreases. The force of attraction between the particles decreases, the space between the particles decreases, and the matter changes its state to solid.
Answer:
Index of Refraction = 1.52
Explanation:
The index of refraction or the refractive index is given as:
Index of Refraction = Sin i/Sin r
where,
i = angle of incidence
r = angle of refraction
In this case of karo syrup, we have the following data:
i = angle of incidence = 30°
r = angle of refraction = 19.24°
Therefore, substituting these values in the equation, we get:
Index of Refraction = Sin 30°/Sin 19.24°
Index of Refraction = 0.5/0.3295
<u>Index of Refraction = 1.52</u>
Hence, the refractive index or the index of refraction of the Karo Syrup is found to be <u>1.52</u><u>.</u>
