About how many millimeters did the brass wire stretch at 60^circ C A 0.9 mm B 1.0 mm C 1.1 mm D 1.3 mm

Question

Answer 1

To determine the correct answer, we need to use the formula for linear expansion:

where:-

is the change in length,-

is the original length,-

is the coefficient of linear expansion for brass,-

is the change in temperature.Given:-

for brass is approximately

,-

.Assuming the original length

is 1 meter (1000 mm) for simplicity:

The closest option to this value is:C 1.1 mm
