A thin copper wire of length l increases its length by 1% when heated from temperature T1 to T2. What is the percentage change in area when a thin copper plate having dimensions 2l×l is heated from T1 to T2?

A thin copper wire of length l increases its length by 1% when heated

1.	A thin copper wire of length l increases its length by 1% when heated from temperature T1 to T2. What is the percentage change in area when a thin copper plate having dimensions 2l×l is heated from T1 to T2?
Answer» A thin copper wire of length $l$ increases its length by 1% when heated from temperature $T_{1}$ to $T_{2}$ . What is the percentage change in area when a thin copper plate having dimensions $2 l \times l$ is heated from $T_{1}$ to $T_{2}$ ?

Two speakers S1 and S2 are derived from the same amplifier and placed at the same distance from x-axis as shown in figure. The speakers vibrate in phase at 680 Hz. A man stands at a point on the x-axis at a very large distance from the origin and starts moving parallel to the y-axis. The speed of sound is 340 m/s. Then, at what angle θ with the x− axis will the intensity of sound drop to a minimum for the first time?
