Ametal rod is 25.000 cm long at 25.0 degrees celsius. when heated to 102.0
degrees celsius, it is 25.054 cm long. what is the coefficient of linear expansion
for this metal?

The coefficient of linear expansion \°C

Explanation:

Given initial temperature °C

And final temperature °C

Initial length

Final length

We have to find the coefficient of linear expansion

The coefficient of linear expansion is defined as the change in length per unit original length divide by the change in temperature.

So, \°C

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.

the right answer is 0.3 meters per second
