Atoddler peddling a tricycle applies a net force of 150n to the pedals. we will assume that 100% of this force is transferred to foward motion. the grandmother of the toddler notice that the toddler on the tricycle is accelerating at a rate of 5m/s. what is the combined mass of the tricycle and toddler?

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

thats how its supposed to be
