Answer:
The Coriolis effect is an apparent deflection in the paths of moving objects caused by Earth's faster speed near the equator than near the poles. In the solar system, the greatest expression of this effect occurs in planetary atmospheres. On Earth, for example, the air around us moves freely above the ground.

Answer:
<h2>22.366 kPa</h2>
Explanation:
The final pressure can be found by using the formula for Boyle's law which is
Since we are finding the final pressure
From the question
58.6 kPa = 58600 Pa
We have
We have the final answer as
<h3>22.366 kPa</h3>

<h3>What is a buffer?</h3>
A buffer is a solution that serves to militate against changes in acidity or alkalinity. The buffer is often made of a solution of a strong acid and its salt or a weak base and its salt.
Now we have the that;
Number of moles of base = 250 /1000 * 0.80 = 0.2 moles
Number of moles of salt = 150/1000 * 0.50 = 0.075 moles
Total volume of the solution = 250 + 150 = 400 mL or 0.4 L
Molarity of the base = 0.2 moles/0.4 L = 0.5 M
Molarity of the salt = 0.075 moles/ 0.4 L = 0.1875 M
pKb = - log( 1.8 x 10^-5) = 4.74
pOH = pKb + log [salt/base]
pOH = 4.74 + log (0.1875/ 0.5)
pOH = 4.33
pH = 14 - 4.33
pH = 9.67
The pH of the solution is obtained to be 9.67.
