( a ) : Pool B
( b ) The final equilibrium temperature will be about 38°C
Attachment 1 : The second pool ( pool B ) had more heat transferred to it, as you can see that it's temperature rose 10 degrees Celcius comparative to pool A, that rose by 9 degrees Celcius. Though the temperature difference is minumum, pool B did have more heat transferred to it.
Attachment 2 : So as we can see, the specific heat of iron and water is given by the units J / kg C. The mass of each substance is also given by kilograms, so there is no need for conversions here. The heat gained by each substance is equivalent to each other, so to determine the final temperature, consider the change in temperature in the formula q = m c Δ T.
For the iron horseshoe, the change in temperature will be as such : Δ T = - 693, where = Final Temperature. Respectively the change in temperature for the water will be Δ T = - 39, where = Final Temperature. Using this information let us solve for .
q = m c Δ T - where q = heat gained, m = mass of substance, c = specific heat of substance
Δ T = - 693 and Δ T = - 39,
- let's say = x,
The final equilibrium temperature will be about 38°C.
First, we have to subtract 4 from each sides of the problem. We should then simplify 11 - 4 to get 7.
Second, we can now rewrite the inequality without the absolute value. We basically have to split the inequality into two to remove the absolute value bars.
Third, subtract 3 from each side, meaning the whole problem. (-7 - 2 = -9) and (7-2 = 5).
This is a function, There is a one to one correspondence between the input and the output and it would pass the vertical line test.
To do this all we need to do is multiply the base by itself how many times the power says.
(-6)² = (-6) × (-6) = 36
Recall that any negative number times another negative number is positive so that is why this would be positive.
So, (-6)² = 36
Hope I helped ya!!
Now we know that our answer cannot be 7 or greater which means that t must be in between -9 and 5.
Since t cannot be greater than 5, the first answer doesn't make sense. The same with the second answer which leaves only the third answer.
The answer is -5 or -9
