Answer:

1,960 kPa

Step-by-step explanation:

The pressure difference between two places with different height can be calculated by using Bernoulli's principle. The principle can be used to find moving fluid, but since the water inside well is static we can remove the part with velocity. You also need to know the density of water, which is 1000 kg/m3. Assuming gravity unit is 9.8 m/s^{2}, the calculation will be:  

P1+ ρgh1 = P2 + ρgh2

P2 -  P1= ρgh2 -ρgh1

P2 - P1= (1000 kg/m3) * (9.8 m/s^{2},) * 200m - (1000 kg/m3) * (9.8m/s^{2},) * 0m

P2 - P1= 1,960,000 kg/ms^{2} = 1,960 kPa

200m deep well has 1,960 kPa higher pressure

Answer:

C. 17/20, rational

Step-by-step explanation:

.25 + 3/5

The least common denominator is 20 so

.25=1/4=5/20

3/5=12/20; therefore,

5/20 + 12/20=17/20.

17/20 is a fraction so is rational.
