How can the ph of a solution be calculated if the poh is known?

a) by taking the negative logarithm of poh
b) by adding the poh to 14
c) by raising 10 to the power of –poh
d) by subtracting the poh from 14

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.

they are made of gases.

they have a spherical shape.

they make energy through fusion.
