(ii) A second drill is used with the extension lead. The power of this drill is 1200 W.
The instructions for using the extension lead include the following information.
When in use the lead may get hot:
DO NOT go over the maximum power
lead wound inside the case: 820 watts
lead fully unwound outside the case: 3100 watts
It would not be safe to use this drill with the extension lead if the lead was left wound
inside the plastic case.
Explain why

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!

i'm on my way to history not a mistory.
