Amachine gear consists of 0.10 kg of iron and 0.16 kg of copper.
how much total heat is generated in the part if its temperature increases by 35 c°? (specific heats of iron and copper are 450 and 390 j/kg⋅°c, respectively.)
a. 910 jb. 3 800 jc. 4 000 jd. 4 400 j

b

Explanation:

Given

mass of iron Gear

mass of copper

specific heat of iron

specific heat of copper

heat gain by iron gear

heat gain by iron gear

Total heat

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14
