Answer:
Explanation:
I'll upload my work shortly as an attachment, but here is my process in words:
- In our first situation we have two capacitors in parallel, which means the charge distribution on both of them is the same. With that, we can find a ratio between the values of Capacitors A and B.
- In our second situation , we add a capacitor parallel to A (I called it C). Because A and C are in parallel, we know that they must have the same potential difference; which should come to be 10V since 90V of the total 100V is on B. Also, the equivalent charge distribution across A and C must be equal to that of the charge distribution at B, because A&C are in series with B. So I added the charges on A&C and set that equal to the charge on B.
- Next, I used the ratio from the first situation to substitute Capacitor A out of the equation. This allows us to solve for B's capacitance. (Note: You could have also substituted B for A and solved for A first if you wanted to.)
- Finally, I used B's capacitance to plug back into the ratio from the first situation to find A's capacitance. And they wanted the answer in micro-Farads, so I went ahead and converted each answer to micro.
1). Take a sample of the substance. The sample should be the largest
possible that will allow it to be be easily handled and the following steps
to be performed with it.
(The density doesn't depend on the size of the sample, and every sample
of the same substance has the same density. But using a larger sample
can improve the accuracy of the measurements you make, and therefore
improve the accuracy of the density you derive for the substance.)
2). Ask or measure the mass of the sample.
3). Ask or measure the volume of the sample.
4). Divide the mass by the volume. Their quotient is the density
of the substance.
Answer:
Specific heat capacity of silver metal = 0.08184 J/kg°C
Explanation:
Given:
Mass of silver metal = 32 kg
Change in thermal energy = 55 J
Change in temperature = 21°C
Find:
Specific heat capacity of silver metal
Computation:
Using Specific heat capacity formula
C = ΔE / mΔT
where;
C = Specific heat capacity
ΔE = Change in thermal energy
m = Mass
ΔT = Change in temperature
C = (55) / (32)(21)
Specific heat capacity of silver metal = 55 / 672
Specific heat capacity of silver metal = 0.08184 J/kg°C
