Some cookware has a stainless steel interior (α=17.3×10−6K−1) and a copper bottom (α=17.0×10−6K−1) for better heat distribution.

balu736 [363]

Answer:

0.0014352 inch

Explanation:

$\alpha_s$ = Coefficient of linear expansion of steel = $17.3\times 10^{-6}\ /K$

$\alpha_c$ = Coefficient of linear expansion of copper = $17\times 10^{-6}\ /K$

$d_0$ = Original diameter = 8 in

$\Delta T$ = Change in temperature

Change in diameter of steel

$\Delta d_s=\alpha_sd_0\Delta T\\\Rightarrow \Delta d_s=17.3\times 10^{-6}\times 8\times (620-22)\\\Rightarrow \Delta d_s=0.0827632\ in$

Change in diameter of copper

$\Delta d_c=\alpha_sd_0\Delta T\\\Rightarrow \Delta d_c=17\times 10^{-6}\times 8\times (620-22)\\\Rightarrow \Delta d_c=0.081328\ in$

Difference in diameter is given by

$\Delta d=\Delta d_s-\Delta d_c\\\Rightarrow \Delta d=0.0827632-0.081328\\\Rightarrow d=0.0014352\ in$

The difference in diameter change for the copper and the steel is 0.0014352 inch

Anita is bouncing a tennis ball on the sidewalk. She drops the ball and then watches it bounce back up. At which point does Anit

Wewaii [24]

Answer:

Just as it reaches the top of the bounce.

Explanation:

When an object reaches to the maximum height, its kinetic energy is equal to 0. It can be calculated as follows :

$K=\dfrac{1}{2}mv^2$

Where

m is mass and v is velocity

In this problem, Anita is bouncing a tennis ball on the sidewalk. She drops the ball and then watches it bounce back up.

It means, when it reaches the top of the bounce, Anita's tennis ball have zero kinetic energy. Hence, the correct option is (d).
