Simplify this expression 8m/14(m+n)

Alright, so...



Like before, multiply 14 to m+n.



Both the top and bottom will be divided by two, since they cannot cancel out any of the letters (you have to have both m/n in all 3 of the numbers/letters)

So,

Your

Explanation:

thermoelecric emf is proportional to temperature difference of the couple .

E = a T , E is emf due to temperature difference of T .

given T = 100 and emf = 50 mV .

50 = a x 100

a = .5 mV / degree Celsius

E = .5 T

when emf = 34.4 mV , T = ?

Put these values in the equation below

E = .5 T

34.4 = .5 T

T = 68.8 degree Celsius.

So temperature of warm liquid = 68.8 °C.
