Answer:
The required specific heat is 196.94 joule per kg per °C
Step-by-step explanation:
Given as :
The heat generated = Q = 85.87 J
Mass of substance (m)= 34.8 gram = 0.0348 kg
Change in temperature = T2 - T1 = 34.29°C - 21.76°C = 12.53°C
Let the specific heat = S
Now we know that
Heat = Mass × specific heat × change in temperature
Or, Q = msΔt
Or, 85.87 = (0.0348 kg ) × S × 12.53°C
Or , 85.87 = 0.4360 × S
Or, S = 
∴ S = 196.94 joule per kg per °C
Hence the required specific heat is 196.94 joule per kg per °C Answer
Answer: 
Step-by-step explanation:
The missing figure is attached.
The perimeter of a rectangle is:

Where "l" is the lenght and "w" is the width.
You can identify in the figure that:

Then, knowing the perimeter of the rectangle, you can make the subsitution into the formula:

Now you must simplify and solve for "z"

Finally, substituting the value of "z" into
, you get:
