Question

(iv) (m2- 10 m + 25) (m – 5): m = -2 verify the results​

Answer 1

Step-by-step explanation:

An aluminum plate has a length of 0.12 m and a width of 0.10 m at 25°C. The plate is uniformly heated to 225 °C. If the linear expansion coefficient for aluminum is 2.3 x 10-5/C what is the change in the area of the plate as a result of the increase in temperature? A) 1.2 x 104m2 B) 6.1 x 10-4 m2 C) 3.2 x 10-m D) 4.9 x 10-6 m2 E) 7.8 x 10-6 m2
