How exactly would Voter ID laws threaten the ability of lower-income earners, seniors, students, minorities, etc. to vote? | [

Not everyone has an ID, and going to get one, even if it's free, can mean taking time off work, or, in the case of the elderly, finding a way to get to an office. It also adds another layer of red tape to the actual voting process. Checking everyone's ID slows dow... | [

When mixing liquids of different temperatures, what will the resulting temperature be? | [
"You're right - it does end up at the exact average. Things get more complicated if there's liquids with different heat capacities involved, such as saline and plain water.
