Answer:
It's used to indicate pressure
It decomposes into CH3COO- and H+ when dissolved in water. The H+ ions react with the water molecules to generate H3O+, making the solution acidic. When NaOH is added to water, it separates into Na+ and OH-. The sodiums have little effect on the solution, but the hydroxyls make it more basic.
Answer:
<em>a. all three resistors in parallel</em>
Explanation:
<u>Combination of Resistors</u>
The power supplied by a power source or V volts is:
where R is the equivalent resistance of the whole circuit connected to the power source.
As shown, the power is inversely proportional to R which means that if R is a minimum, P is a maximum.
The problem reduces now to find the combination of resistors that produces the least value of its equivalent. If three resistors are connected in series, the equivalent is the sum of all them
This equation gives R a value that is greater than the greatest of all three resistances.
If they are connected in parallel, the equivalent is given by
This equation produces for R a value that is smaller than the smallest value from the three resistances.
Any other combination of resistors will produce intermediate values between the maximum (series) and the minimum (parallel), thus:
a. all three resistors in parallel
Answer:
5.82x10^-3
Explanation:
If the decimal moves right I think it goes negative in the exponent because the starting number is small...or less than 1
I think
