Answer:
The new length is 1.20138 m
Explanation:
1- We get the increase in length:
The old length = 1.2 m
The coefficient of expansion of of aluminum is 23 * 10⁻⁶ /K.
The old temperature is 15°C.
The new temperature is 65°C
The increase in length= old length * coefficient of expansion *change in temperature
The increase in length = 1.2 * 23 * 10⁻⁶ * (65-15)
The increase in length = 0.00138 m
2- getting the new length:
new length = old length + increase in length
new length = 1.2 + 0.00138
new length = 1.20138 m

Answer:
c. Central Powers.
b. Allied Forces.
d. Axis Powers.
B. If one bulb burns out, then none of the others will light up.
C. It is difficult to tell which path an electric charge is following in a series circuit
D. Only one bulb can be connected in a series circuit.
If one bulb goes out then all the others won't light up because electricity will be cut off. It's a disadvantage because in a parallel circuit if one bulb burns out all the others will still be on because they won't be affected. I hope I've helped you ☺
