Calculate the change in length on a copper (coefficient of linear expansion for copper is 17 * 10-6 / oc) rod that is 25 meters that undergoes a temperature change of 15 o.

0.6375 cm

Explanation:

coefficient of linear expansion of copper, α =

Lo = 25 m

Δ T = 25 degree C

According to the formula of thermal expansion which is linear in nature is given by

Where, ΔL be the change in length

=0.6375 cm

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.

explanation:

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
