The faster/slower one i think is faster because the colder the air, the closer the particals are, and for #2 it's because the door is condensed, and the atoms are closer, therefore meaning that the sound particals don't spread, like they would in air, they're more compact (meaning they're) easier to hear, or you just have a good listening ear.

A 4 V power source is connected in parallel to four resistors: 1, 2, 2, and 3. Find the total current.

Keith_Richards [23]

Answer:

Explanation:

Equivalent resistance is 1 / ((1/1) + (1/2) + (1/2) + (1/3)) = 3/7 Ω

I = V/R = 4(7/3) = 28/3 = 9.3 A
